A card is selected to from a standard deck of 52 card what are the odds of selecting a red 9
The odds of selecting a red 9 is 1/26.
Probability of an event E is represented by P(E) can be defined as (the number of favorable outcomes) / (Total number of outcomes).
Given the total number of cards in a standard deck = 52
there can be only two red9 as one 9 from heart and one red from diamond.
So the number of outcome for red 9 =2
the probability of odds of selecting red 9 is \(\frac{2}{52}\) which can be further simplified into \(\frac{1}{26}\).
Therefore , The odds of selecting a red 9 is 1/26.

Write the equation for a parabola with a focus at (-7,-5) and a directrix at x = -4
Answer:
y² + 10y + 6x + 58 = 0
Step-by-step explanation:
Focus of the parabola has been given as (-7, -5) and directrix as x = -4
Let a point on the parabola is (x, y).
By the definition of a parabola, "distance of a point on parabola is equidistant from focus and directrix".
Distance from focus of the given point = \(\sqrt{(x+7)^2+(y+5)^2}\)
Distance of the point from directrix = \(\sqrt{(x+4)^2}\)
Therefore, equation of the parabola will be,
\(\sqrt{(x+7)^2+(y+5)^2}=\sqrt{(x+4)^2}\)
\((x+7)^2+(y+5)^2=(x+4)^2\)
x² + 14x + 49 + y² + 10y + 25 = x² + 8x + 16
y² + 14x + 10y + 74 = 8x + 16
y² + 10y + 6x + 58 = 0

you order a cell phone case and 2 screen protectors online for a total of $18.95. your friend orders 2 cell phone cases and 5 screen protectors at the same unit prices for a total of $41.40. what is the cost of each cell phone case? each screen protector?
Answer:
Step-by-step explanation:
The cost of each cell phone case is $7.15, and the cost of each screen protector is $2.25.
To solve this problem, we can create a system of equations.
Let x represent the cost of one cell phone case and y represent the cost of one screen protector.
Then, we can write the following equations:
1x + 2y = 18.95 (equation 1)
2x + 5y = 41.40 (equation 2)
We can solve for x and y by multiplying equation 1 by 2 and subtracting it from equation
2.2x + 5y = 41.40(2 x 1x + 2 x 2y = 2 x 18.95)2x + 5y = 41.4002x + 4y = 37.90
Subtracting equation 1 from equation 2 gives us:
2x + 5y = 41.400- (0.2x + 0.4y = 3.790)
1.8x + 4.6y = 37.61
Now we can solve for y.
1.8x + 4.6y = 37.61
=> 46y = 46.29
=> y = 1.05
Then we can solve for x using equation
1.1x + 2y = 18.95
=> 1x + 2(1.05) = 18.95
=> x = 7.15

Which of the following symbols is used for a column alias containing spaces?
A. ''
B. ||
C. " "
D. //
The correct symbol used for a column alias containing spaces is C. " " (quotation marks).
In SQL, when we want to assign a column alias containing spaces, we enclose the alias within double quotation marks. This is done to differentiate the alias from other SQL keywords or to handle cases where the alias includes special characters, spaces, or is case-sensitive.
For example, consider the following SQL query:
SELECT column_name AS "Column Alias"
FROM table_name;
In this query, we are selecting a column named "column_name" from the table "table_name" and assigning it the alias "Column Alias" containing spaces. By enclosing the alias within double quotation marks, we indicate to the database that it should treat the entire string as a single identifier or alias.
Using other symbols such as '', ||, or // will not achieve the desired result of creating an alias with spaces. These symbols have different meanings in SQL.
'' (two single quotation marks) typically represents an empty string or a string literal in SQL.
|| (double vertical bars) is the concatenation operator in some SQL dialects, used to combine strings or values.
// (double forward slashes) is commonly used for comments in various programming languages and does not have any special meaning for column aliases in SQL.

25th of February is on a Thursday, what day of week would it be on every four years
In each subsequent leap year, February 25th will be on the next day of the week.
To determine the day of the week for February 25th in leap years, we can use the fact that every leap year is divisible by 4. This means that the date will shift by one day of the week each leap year.
Since February 25th falls on a Thursday, we can start counting the number of leap years from that year and determine the day of the week for subsequent leap years.
Here is the pattern:
In the first leap year (4 years after the starting year), February 25th will be on a Friday.
In the second leap year (8 years after the starting year), February 25th will be on a Saturday.
In the third leap year (12 years after the starting year), February 25th will be on a Sunday.
In the fourth leap year (16 years after the starting year), February 25th will be on a Monday.
In the fifth leap year (20 years after the starting year), February 25th will be on a Tuesday.
In the sixth leap year (24 years after the starting year), February 25th will be on a Wednesday.
In the seventh leap year (28 years after the starting year), February 25th will be on a Thursday.
In the eighth leap year (32 years after the starting year), February 25th will be on a Friday.
And so on.
From this pattern, we can see that every four years, the day of the week for February 25th will advance by one day. This is because each leap year adds an extra day to the calendar, shifting all subsequent dates by one day.
Therefore, for example, if February 25th falls on a Thursday in a non-leap year, it will be on a Friday in the next leap year, Saturday in the following leap year, and so on.
In summary, the day of the week for February 25th will advance by one day in each subsequent leap year.

The diameter of ball bearing are ditributed normally. The mean diameter i 81 millimeter and the variance i 16. Find the probability that the diameter of a elected bearing i greater than 85 millimeter. Round your anwer to four decimal place
the probability that the diameter of a elected bearing is greater than 85 millimeter P(diameter > 85) = P(z > (85-81)/4) = P(z > 1) = 0.1587
The diameter of ball bearings is normally distributed, with a mean of 81 millimeters and a variance of 16.
To calculate the probability that a selected bearing has a diameter greater than 85 millimeters, we first calculate the z-score for 85 millimeters.
We subtract 81 from 85 to get 4, and divide by 4 to get 1 for the z-score.
We the look up the probability for a value of 1 in the z-table, which is 0.1587.
This is the probability that a selected bearing has a diameter greater than 85 millimeters, rounded to four decimal places.

(b) When k = 3/4, area of the new triangle = 56.25 square inches.
Given that,
A triangle has area 100 square inches.
It's dilated by a factor of k = 0.25.
When the triangle is dilated by a scale factor of k, then, each of the base and height is dilated by the scale factor of k.
So new area of the triangle after the dilation with the original triangle having base = b and height = h is,
Area of new triangle = 1/2 (kb)(kh) = k² (1/2 bh) = k² × Area of original triangle
Here original area = 100 square inches.
k = 0.25
New area = (0.25)² 100 = 6.25 square inches
So the correct statement is that of Lin.
Mai may found the new area by just multiplying the scale factor with 100, instead of taking the square of the scale factor. That is why she got 25 square inches as the new area.
2) (a) When k = 9,
Area of the new triangle = 9² (100) = 8100 square inches

Swift, lets say we have a table view of 10 rows and i want to
change the rows of 9 & 10 to rowheights 0 to hide it from the
view. rewrite this logic to hide the last two rows in the table
view
To hide the last two rows in a table view in Swift and set their row heights to 0, you can modify the table view's delegate method `heightForRowAt` for the respective rows.
In Swift, you can achieve this by implementing the UITableViewDelegate protocol's method `heightForRowAt`. Inside this method, you can check if the indexPath corresponds to the last two rows (in this case, rows 9 and 10). If it does, you can return a row height of 0 to hide them from the view. Here's an example of how you can write this logic:
```swift
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
let numberOfRows = tableView.numberOfRows(inSection: indexPath.section)
if indexPath.row == numberOfRows - 2 || indexPath.row == numberOfRows - 1 {
return 0
}
return UITableView.automaticDimension
}
```
In the above code, `tableView(_:heightForRowAt:)` is the delegate method that returns the height of each row. We use the `numberOfRows(inSection:)` method to get the total number of rows in the table view's section. If the current `indexPath.row` is equal to `numberOfRows - 2` or `numberOfRows - 1`, we return a height of 0 to hide those rows. Otherwise, we return `UITableView.automaticDimension` to maintain the default row height for other rows.
By implementing this logic in the `heightForRowAt` method, the last two rows in the table view will be effectively hidden from the view by setting their row heights to 0.

\(\begin{gathered} A=\mleft\lbrace2,5\mright\rbrace \\ B=\mleft\lbrace1,2,3,4,5\mright\rbrace \end{gathered}\)The union of the two sets is the combined set of all numbers that are in the two sets.
Therefore, we have that:
\(A\cup B=\mleft\lbrace1,2,3,4,5\mright\rbrace\)That is the answer.
a bag contains 16 coins each with a different date. the number of possible combinations of three coins from the bag is
The number of possible combinations of three coins from the bag of 16 coins with different dates can be calculated using the formula for combinations, which is nCr = n! / r!(n-r)!, where n is the total number of objects, r is the number of objects to be chosen, and ! denotes factorial (the product of all positive integers up to the given number).
In this case, we have n = 16 (the total number of coins in the bag) and r = 3 (the number of coins to be chosen for each combination). Using the formula for combinations, we can calculate the number of possible combinations as follows:
nCr = 16! / 3!(16-3)!
nCr = (16 x 15 x 14) / (3 x 2 x 1)
nCr = 560
Therefore, 560 possible combinations of three coins can be chosen from the bag of 16 coins with different dates. These combinations could represent different historical events, significant dates, or other symbolic meanings depending on the dates inscribed on the coins. The calculation of combinations is an important concept in combinatorics and probability theory, and it has many real-world applications in fields such as statistics, economics, and computer science.

The alternating series test can be used to show convergence of the alternating series I, II, and III given in the options and the correct answer to this question is Option A. I only.
The alternating series test is a method used to determine the convergence or divergence of alternating series. According to the alternating series test, an alternating series converges if the absolute value of its terms decreases monotonically to zero. In other words, if the absolute value of the terms in an alternating series eventually becomes smaller and smaller until it is less than or equal to a certain positive number, then the series converges.
In series, I, the absolute value of the terms decreases monotonically to zero since the terms eventually become smaller and smaller. Therefore, series I converge by the alternating series test.In series II, the absolute value of the terms does not decrease monotonically to zero, since the terms eventually increase in magnitude. Therefore, the alternating series test cannot be used to show the convergence or divergence of series II.In series III, the absolute value of the terms decreases monotonically to zero since the terms eventually become smaller and smaller. Therefore, series III converges by the alternating series test.In conclusion, the alternating series test can be used to show the convergence of series I and III, but not for series II.

The approximate probability that the total amount of tips exceeds 720 dollars is 0.9332 or 93.32%.
To find the probability that the total amount of tips exceeds 720 dollars, we need to use the Central Limit Theorem. Given that the mean of individual tips is 7.5 dollars, and the standard deviation is 2 dollars, we can calculate the mean and standard deviation for the total amount of 100 tips.
1. Calculate the mean of 100 tips: Mean_total = Mean_tip * Number_of_tips = 7.5 * 100 = 750 dollars.
2. Calculate the standard deviation of 100 tips: SD_total = SD_tip * sqrt(Number_of_tips) = 2 * sqrt(100) = 20 dollars.
3. Calculate the z-score: z = (X - Mean_total) / SD_total = (720 - 750) / 20 = -1.5.

Therefore, all possible results are (0,1,0,0),(1,0,1,0),(1,0,0,1),(0,1,1,1)
Would this be correct?
The correct set of possible results would be (0, 1, 0, 0), (1, 2, 1, 0) and (1, 2, 0, 1).
Your approach seems to be correct, but there seems to be a minor mistake in your final list of possible solutions. Let's go through the steps to clarify.
Given the initial conditions z=t=0, you obtained a partial solution (0,1,0,0).
Next, you solved the homogeneous equations for z=1 and t=0, which resulted in a solution (1,1,1,0).
Similarly, solving the homogeneous equations for z=0 and t=1 gives another solution (1,1,0,1).
To find the general solution, you combine the partial solution with the solutions obtained in the previous step, using parameters a and b.
(0,1,0,0) + a(1,1,1,0) + b(1,1,0,1)
Expanding this expression, you get:
(0+a+b, 1+a+b, 0+a, 0+b)
Simplifying, you obtain the following set of solutions:
(0, 1, 0, 0)
(1, 2, 1, 0)
(1, 2, 0, 1)
Therefore, the correct set of possible results would be:
(0, 1, 0, 0)
(1, 2, 1, 0)
(1, 2, 0, 1)
Note that (0, 1, 1, 1) is not a valid solution in this case, as it does not satisfy the initial condition z = 0.

Use Theorem 2.1.1 to verify the logical equivalences in 50–54. Supply a reason for each step.
∼(p ∨ ∼q) ∨ (∼p ∧ ∼q) ≡ ∼p
Reference:
Theorem 2.1.1 states that "If p, q, and r are logical expressions, then p ∨ (q ∧ r) ≡ (p ∨ q) ∧ (p ∨ r). To verify the equivalence ∼(p ∨ ∼q) ∨ (∼p ∧ ∼q) ≡ ∼p, we will break it down into smaller parts and use Theorem 2.1.1 to rearrange them. First, note that ∼(p ∨ ∼q) ≡ (∼p ∧ q).
Then we can rewrite the left-hand side as (∼p ∧ q) ∨ (∼p ∧ ∼q). Applying Theorem 2.1.1 to the right-hand side yields ∼p ∨ (q ∧ ∼q). Since q ∧ ∼q is always false, the right-hand side simplifies to just ∼p.
Therefore, we have shown that ∼(p ∨ ∼q) ∨ (∼p ∧ ∼q) ≡ ∼p.
Step 1: Use the distributive property to rewrite p ∧ (q ∨ r) as (p ∧ q) ∨ (p ∧ r):(p ∧ q) ∨ (p ∧ r) ≡ (p ∧ q) ∨ (p ∧ r)
Reason: Distributive property
Step 2: The left-hand side and right-hand side are the same, so the statement is logically equivalent. p ∧ (q ∨ r) ≡ (p ∧ q) ∨ (p ∧ r)
Reason: Theorem 2.1.151. p ∨ (q ∧ r) ≡ (p ∨ q) ∧ (p ∨ r)
Step 1: Use the distributive property to rewrite p ∨ (q ∧ r) as (p ∨ q) ∧ (p ∨ r):(p ∨ q) ∧ (p ∨ r) ≡ (p ∨ q) ∧ (p ∨ r)
Reason: Distributive property

Answer: The relationship between radius and diameter in the context above is that the diameter of the bucket is twice the radius. In other words, the radius is half of the diameter.
The radius of a circle is the distance from the center of the circle to any point on its circumference. It is represented by the letter 'r' in formulas and calculations.
To determine the maximum height of the water in the bucket, we need to find the radius first. Since the diameter of the bucket is given as 31.2 cm, we can calculate the radius as follows:
Radius = Diameter / 2Radius = 31.2 cm / 2Radius = 15.6 cm
Using the formula for the volume of a cylinder, we can calculate the maximum height (h) of the water:
Volume = π x (radius)^2 x height20,000 cm³ = 3.142 x (15.6 cm)^2 x height
Solving for height:
height = 20,000 cm³ / (3.142 x (15.6 cm)^2)height ≈ 20,000 cm³ / (3.142 x 243.36 cm²)height ≈ 20,000 cm³ / 765.44 cm²height ≈ 26.1 cmTherefore, the maximum height of the water in the bucket is approximately 26.1 cm.
3.4. (a) To calculate the unused area of the rectangular floor, we need to subtract the total area covered by the buckets from the total area of the rectangle. Since the buckets are cylindrical, the area they cover is the sum of the areas of their circular tops.
Area of a circle = π x (radius)^2
Area covered by one bucket = π x (15.6 cm)^2Area covered by one bucket ≈ 764.32 cm²
Total area covered by 20 buckets (assuming 20 buckets fit on the pallet) = 20 x 764.32 cm²
Total area covered by 20 buckets ≈ 15,286.4 cm²
Total area of the rectangular floor = length x widthTotal area of the rectangular floor = 120 cm x 100 cmTotal area of the rectangular floor = 12,000 cm²
Unused area = Total area of the rectangular floor - Total area covered by 20 buckets
Unused area = 12,000 cm² - 15,286.4 cm²Unused area ≈ -3,286.4 cm²
Since the unused area is negative, it suggests that the buckets do not fit on the pallet as shown in the diagram. There seems to be an overlap or discrepancy in the given information.
(b) Without a diagram provided, it is not possible to determine length C as mentioned in the question. Please provide a diagram or further information for an accurate calculation.
Unfortunately, I cannot calculate the percentage by which the length of the pallet should be changed without the required information or diagram.
