literally anybody help me please!! all you have to do is find the slope and y intercept for the equation on the picture. PLEASE HELP ME ASAP!!
Answers
The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b). The y-coordinate is the value of b in the slope-intercept form. The Slope is - ⅖.
What is the Slope and Y-intercept of a Line?Y-intercept = (0, 4), where b = 4
Given the linear equation in standard form, 2x + 5y = 20, where A = 2, B = 5, and C = 20:
Start by transforming the standard equation into its slope-intercept form, y = mx + b, where m = slope, and b = y-intercept.
Subtract 2x from both sides:
2x -2x + 5y = - 2x + 20
5y = -2x + 20
Divide both sides by 5 to isolate y:
y = - ⅖x + 4 ⇒ This is the slope-intercept form where the slope, m = -⅖, and the y-intercept, b = 4. The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates of (0, b). The y-coordinate is the value of b in the slope-intercept form. Therefore, the y-intercept is (0, 4).

Answers
Answer:
MN = 25
Step-by-step explanation:
If LN=45, then the addition of both quantities will be 45.
LN = 3x + 2 + x + 19
3x + 2 + x + 19 = 45
4x + 21 = 45
4x = 45 - 21 = 24
x = 6
Now that we found the value of "x", we can find the lenght of MN
MN = x + 19
MN = 6 + 19
MN = 25
Hope it was helpful ;)
Answer: MN = 25
Step-by-step explanation:
Since the length is already given we just add the equations equal to it.
45 = 3x + 2 + x + 19 Combine like terms
45 = 4x + 21 Subtract 21 from both sides
24 = 4x Divide by 4
x = 6
Now we plug x into the equation needed.
X + 19
6 + 19 = 25
a circle in the coordinate plane passes through points (-3,-2) and (1,4). what is the smallest possible area of that circle?
Answers
The smallest possible area of the circle with the points (-3,-2) and (1,4) is 13π.
Given, the endpoints of the circle are given:
(-3,-2) = (x₁,y₁)
(1,4) = (x₂,y₂)
The circle with the smallest possible area that passes through the points (-3, -2) and (1, 4) is a circle with a diameter whose endpoints are these two points.
we are asked to determine the area of the circle = ?
first calculate the distance between the points:
distance = √(x₁-x₂)²+(y₁-y₂)²
d = √(-3-1)²+(-2-4)²
d = √(-4)² + (-6)²
d = √16+36
d = √52
d = 2√13
Thus, the radius has a length of r = √13,
and the area of the circle is A = π x (√13)²
= 13π.
Hence we get the area of the circle as 13π..

Four friends took a road trip that lasted 50 hours round trip. Denny drove five times as long as Connor, while Pat and Seth drove the same amount of time. Connor drove half as long as Pat. How long did Denny drive?
Answers
Answer:
Denny drove for 25 hours
Step-by-step explanation:
Here, we want to calculate the amount of time Denny drove
Let the time Connor drove be c
Denny drove 5 times as this which is 5 * c = 5c
Conor drove half as long as Pat
So this means that Pat drove 2 times Conor = 2c
Seth is same as Pat which is also 2c
Adding all gives 50
c + 5c + 2c + 2c = 50
10c = 50
c = 50/10
c = 5 hours
Denny = 5 * c
= 5 * 5 = 25 hours

Describe Right Angled Triangle?A right-angled triangle is a triangle that has one angle measuring 90 degrees, which is known as the right angle. The sides adjacent to the right angle are known as the legs of the triangle, while the side opposite the right angle is known as the hypotenuse.
The Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs, is one of the fundamental theorems of mathematics and is used extensively in various fields.
Let's call the width of the shelf "x". According to the given diagram, we have a right triangle where the base is x, the perpendicular is 10 inches, and the angle between the hypotenuse and the perpendicular is 45 degrees.
Using trigonometric ratios, we know that:
tan(45) = perpendicular/hypotenuse
tan(45) = 10/x
Since tan(45) is equal to 1, we can simplify the equation to:
1 = 10/x
Solving for x, we get:
x = 10

You measure 31 randomly selected textbooks' weights, and find they have a mean weight of 64 ounces. Assume the population standard deviation is 10 ounces. Based on this, construct a 95% confidence interval for the true population mean textbook weight.
Give your answers as decimals, to two places.
Answers
The 95% confidence interval for the true population mean textbook weight is (61.68, 66.32) ounces.
To construct a confidence interval, we can use the formula:
Confidence Interval = sample mean ± (critical value) * (standard deviation / √sample size)
In this case, the sample mean weight is 64 ounces, and the population standard deviation is 10 ounces. Since the sample size is 31, we need to determine the critical value for a 95% confidence level.
The critical value can be found using a standard normal distribution table or a statistical calculator. For a 95% confidence level, the critical value is approximately 1.96.
Plugging the values into the formula, we have:
Confidence Interval = 64 ± (1.96) * (10 / √31)
Calculating the expression inside the parentheses:
10 / √31 ≈ 1.79
Multiplying 1.96 by 1.79:
1.96 * 1.79 ≈ 3.51
Finally, we can construct the confidence interval:
64 - 3.51 ≈ 61.68
64 + 3.51 ≈ 66.32
Therefore, the 95% confidence interval for the true population mean textbook weight is approximately (61.68, 66.32) ounces.

A building is constructed on top of a cliff that is 300 meters high. A person standing on level ground below the cliff observes that the angle of elevation to the top of the building is 72° and the angle of elevation to the top of the cliff is 63°.
a. How far away is the person from the base of the cliff?
b. What is the building’s height?
Answers
The distance from the person to the base of the cliff is 269.78 meters.
The height of the building from the base of the cliff is 829.37 meters
The situation forms right angle triangle.
The building is constructed on top the cliff that is 300 meters high.
Right angle triangle:Right angle triangle has one of its sides as 90 degrees. Therefore, the sides can be found using trigonometric ratios.
The height of the building from the cliff is 300m. let's find the hypotenuse side of the angle of elevation formed to the cliff.
Using sin rule,
300 / sin (72 - 63) = y / sin (180 - 162)
300 / sin 9 = y / sin 18
300 sin 18 = y sin 9
y = 300 sin 18 / sin 9
y = 92.7050983125 / 0.156
y = 594.230769231
Therefore, how far the person to the base of the cliff can be calculated as follows;
cos 63 = adjacent / hypotenuse
cos 63 = x / 594.2307
x = 594.2307 cos 63
x = 269.775092454
x = 269.78 meters
Therefore, the distance from the person to the base of the cliff is 269.78 meters.
height of the cliff / 269.78 = tan 63
height of cliff = 269.78 tan 63
height of cliff = 529.37493165
height of cliff = 529.37
The height of the building = 300 + 529.37 = 829.37493165 = 829.37 meters

You find a slice of American cheese under a shelf in the garage. If the cheese has a shelf life of e t days, how old is the cheese you found if the slice was only 13.6% of the original size? 0.0386 after wa shelf life of e size?
Answers
The cheese slice you found in your garage is approximately 46.36 days old, based on the given decay rate and the percentage of its original size.
Let's start by denoting the initial size of the cheese slice as S, and the remaining size found as R. Given that the cheese slice is 13.6% of its original size, we can represent this as:
R = 0.136 * S
Now, let's consider the decay rate of the cheese, which is given as 0.0386. Assuming that the cheese decay follows exponential decay, we can write the formula for the decay as:
R = S * (1 - decay_rate) ^ t
Where 't' is the age of the cheese in days. We can now substitute the value of R in the decay formula:
0.136 * S = S * (1 - 0.0386) ^ t
Since we're interested in finding 't', we can simplify the equation by dividing both sides by S:
0.136 = (1 - 0.0386) ^ t
Now, to solve for 't', we can take the natural logarithm of both sides:
ln(0.136) = ln((1 - 0.0386) ^ t)
Using the logarithmic property, we get:
ln(0.136) = t * ln(1 - 0.0386)
Finally, divide both sides by ln(1 - 0.0386) to find 't':
t = ln(0.136) / ln(1 - 0.0386)
Using a calculator, we find that t ≈ 46.36 days.

Two interior angles of a triangle each measure 34 degrees.What is the measure of the third interior triangle?
Answers
In a triangle with two interior angles that are both 34 degrees, the third interior angle is 112 degrees.
The measure of the third interior angle of a triangle can be found by subtracting the sum of the two given angles from 180 degrees.
In this case, if two interior angles of a triangle each measure 34 degrees, the measure of the third interior angle can be calculated as follows:
Finding the sum of the two given angles.
34 + 34 = 68 degrees
Subtracting the sum from 180 degrees.
180 - 68 = 112 degrees
Therefore, the measure of the third interior angle of the triangle is 112 degrees.
In conclusion, the third interior angle of a triangle has a measure of 112 degrees when the first two interior angles of the triangle each measure 34 degrees.
This can be determined by subtracting the sum of the given angles from 180 degrees, as the sum of the interior angles of a triangle is always 180 degrees.

The domain is (-∝, ∝) and the range is y > 0
How to determine the domain and the rangeFrom the question, we have the following parameters that can be used in our computation:
y = 2^x
The domain of the function is the set of all real numbers
This is so because there is no restriction on the input values
The range of the function is the set of positive real numbers
Since any positive number can be obtained by raising 2 to a power, and the function is never negative or zero.
We can write the range as y > 0.

find the support and confidence of this transaction
A = I2, B = I3
Let 1 = {1,, I, I...... 1.} be a set of items, where I, denotes an item ID. Consider the transaction database D, defined in the table below: Transaction ID List of Items in the Transaction T₂ I, I,
Answers
For confidence interval: support of the association rule A to B is 0.5 and the confidence of the association rule A to B is 0.5.
For Support and confidence of the association rule A - B
To determine the support and the confidence of the association rule A → B, where A = {1, }, B = {1}, we use the formulas given below:
Support(A → B) = frequency of (A, B) / N
Confidence(A → B) = frequency of (A, B) / frequency of A
where N is the number of transactions in the database.
To find the frequency of (A, B) and the frequency of A.
Thus Frequency of (A, B) = 1
Since there is only one transaction in the database where both A and B occur, the frequency of (A, B) is 1.
Frequency of A = 2
The itemset {1, } occurs in two transactions T₁ and T₂.
Hence, the frequency of A is 2.

Solve for x in the equation x squared minus 12 x 36 = 90.
Answers
Answer:
x = ±3√58
Step-by-step explanation:
Given
x² - (12 x 36) = 90Solving
x² - 432 = 90x² = 522x² = 9 x 58x = ±3√58Answer:
\(x =\) ± \(22.85\)
Step-by-step explanation:
Step 1: Multiply 12 * 36
\(x^2 - (12 * 36) = 90\)
\(x^2 - 432 = 90\)
Step 2: Add 432 to both sides
\(x^2 - 432 + 432 = 90 + 432\)
\(x^2 = 522\)
Step 3: Square root both sides
\(\sqrt{x^2} = \sqrt{522}\)
\(x =\) ± \(22.85\)
Answer: \(x =\) ± \(22.85\)
a researcher found that out of 100 boys, 56 had dogs in their household, while only 43 out of 100 girls did. she plans to compute a confidence interval for the difference in proportions. compute the standard error to use in this formula.
Answers
The standard error to be used in the formula of a confidence interval for the difference in proportions is 0.07.
The estimated standard deviation of a statistical sample population is known as the standard error (SE) of a statistic.
By utilising standard deviation, the standard error is a statistical concept that assesses how well a sample distribution represents a population. In statistics, the difference between a sample mean and the population's actual mean is known as the standard error of the mean.
The standard error's primary function is to indicate how divergent the population mean will be from the sample mean. Because it aids in determining how well the standard data reflect the entire population, the standard error is significant. We may readily draw reliable conclusions by calculating the standard error in order to determine how representative our sample is of our population.
56 out of 100 boys = P1 = 0.56
43 out of 100 girls = P2 = 0.43
The formula for standard is given by,
\(S.E=\sqrt{\frac{P_1(1-P_1)}{n1} +\frac{P_2(1-P_2)}{n2} } \\=\sqrt{\frac{0.56(1-0.56)}{100} +\frac{0.43(1-0.43)}{100} } \\\\= \sqrt{\frac{0.2464}{100} +\frac{0.2451}{100} } \\\\=\sqrt{0.004915} \\=0.07\)
Therefore, the standard error is 0.07.
