There are 40 children watching a magic show. 24 of the children are boys, and 16 of the children are girls. The magician needs to select 4 children to help him with his show. What is the probability that all 4 helpers will be girls
Answers
Answer:
1.99%. (2% rounded)
Step-by-step explanation:
The total number of ways to select 4 children out of 40 is given by the combination formula:
C(40,4) = 40! / (4! * (40-4)!) = 91,390
The number of ways to select 4 girls out of 16 is given by the combination formula as well:
C(16,4) = 16! / (4! * (16-4)!) = 1,820
Therefore, the probability of selecting 4 girls out of the group of 40 children is:
P(4 girls) = C(16,4) / C(40,4) = 1,820 / 91,390 ≈ 0.0199 or 1.99%
So the probability that all 4 helpers will be girls is approximately 1.99%

Use technology to find points and then graph the function y=^2(square root)x-1 - 2
What are the points of this equation?
Answers
The graph for the function y = ∛(x-1)-2 is attached below.
To find points and graph the function y = ∛(x-1)-2, we can follow these steps:
Choose some x-values to evaluate the function. Let's select a range of x-values to get a sense of the overall shape of the graph. Substitute each x-value into the function to find the corresponding y-values. Plug in each x-value into the equation y = ∛(x-1)-2 and calculate the resulting y-value.Let's calculate the points for the function y = ∛(x-1)-2 using the selected x-values:
x = -5: y = ∛(-5-1)-2 ≈ ∛(-6)-2 ≈ -2.72
x = -4: y = ∛(-4-1)-2 ≈ ∛(-5)-2 ≈ -2.58
x = -3: y = ∛(-3-1)-2 ≈ ∛(-4)-2 ≈ -2.44
x = -2: y = ∛(-2-1)-2 ≈ ∛(-3)-2 ≈ -2.29
x = -1: y = ∛(-1-1)-2 ≈ ∛(-2)-2 ≈ -2.15
x = 0: y = ∛(0-1)-2 ≈ ∛(-1)-2 ≈ -2.00
x = 1: y = ∛(1-1)-2 ≈ ∛(0)-2 ≈ -2.00
x = 2: y = ∛(2-1)-2 ≈ ∛(1)-2 ≈ -1.85
x = 3: y = ∛(3-1)-2 ≈ ∛(2)-2 ≈ -1.71
x = 4: y = ∛(4-1)-2 ≈ ∛(3)-2 ≈ -1.57
x = 5: y = ∛(5-1)-2 ≈ ∛(4)-2 ≈ -1.43

Step-by-step explanation:
all rows, diagonals, and columns= 48
correct me if im wrong
Answer:
a=23
b=7
c=15
d=9
Step-by-step explanation:
first, we can see that the sum of a row, column, or diagonal is 48, because we can add the diagonal consisting of numbers 8, 16, and 24.
Next, we can find a:
8+17+a=48
a= 23
Then find b:
17+b+24=48
b=7
now find the middle column:
23+16+d=48, remember that a is 23
d=9
finally, we can find c:
8+25+c=48
or
9+24+c=48
both give c=15 as the answer
Chan is throwing a ball from the ground at an initial velocity of 22.1 meters per seconds. He threw the ball so high that on it's way down it got stuck in a tree 10 meters high. How long was the ball in the air before it got stuck in the tree?
a.4 sec
b.4.51 sec
c.24.9 meters
d.2.25 sec
Answers
The ball's height y at time t is
y = (22.1 m/s) t - 1/2 gt ²
where g = 9.80 m/s² is the magnitude of the acceleration due to gravity.
Solve for t when y = 10 m:
10 m = (22.1 m/s) t - 1/2 gt ²
→ t = 0.510 s or t = 4.00 s
The first time refers to when the ball first reaches 10 m on its way up, so t = 4.00 s and the answer is A.
For the third week of April, Patricia Thomas worked 53 hours. Patricia earns $11.90 an hour. Her employer pays overtime for all hours worked in excess of 40
hours per week and pays 1.5 times the hourly rate for overtime hours.
Calculate the following for the third week of April (round your responses to the nearest cent if necessary):
1. Regular pay amount
2. Overtime pay
3. Gross pay
Answers
Given statement solution is :- For the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.
To calculate Patricia's pay for the third week of April, we'll need to determine her regular pay, overtime pay, and gross pay.
Regular Pay:
Patricia worked 53 hours, but only 40 hours are considered regular hours. Therefore, the regular pay is calculated as follows:
Regular Pay = Regular Hours x Hourly Rate
Regular Pay = 40 hours x $11.90/hour
Regular Pay = $476
Overtime Pay:
Since Patricia worked 53 hours in total and 40 of those are regular hours, the remaining 13 hours are considered overtime hours. Overtime pay is calculated by multiplying the overtime hours by 1.5 times the hourly rate.
Overtime Pay = Overtime Hours x (Hourly Rate x 1.5)
Overtime Pay = 13 hours x ($11.90/hour x 1.5)
Overtime Pay = 13 hours x $17.85/hour
Overtime Pay = $231.45
Gross Pay:
Gross Pay is the sum of Regular Pay and Overtime Pay.
Gross Pay = Regular Pay + Overtime Pay
Gross Pay = $476 + $231.45
Gross Pay = $707.45
Therefore, for the third week of April, Patricia's:
Regular pay amount is $476.
Overtime pay is $231.45.
Gross pay is $707.45.

Exercise 4.3. Determine the exact probability of drawing a 10 from a shuffled pinochle deck. (In a pinochle deck, there are 48 cards. There are six values: 9, 10, Jack, Queen, King, Ace. There are two copies of each value in each of the standard four suits: hearts, diamonds, clubs, spades.)
Answers
Answer:
\(\frac{1}{6}\) probability of drawing a 10 from a shuffled pinochle deck.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Total of 48 cards.
Of those, there are 2*4 = 8 cards that are 10. So
\(p = \frac{8}{48} = \frac{1}{6}\)
\(\frac{1}{6}\) probability of drawing a 10 from a shuffled pinochle deck.
During a single day at the radio station WMZH, the probability that a particular song is played is 1/6. What is the probability that this song will be played on exactly 6 days out of 7 days? Round your answer to the nearest thousandth.
Answers
Around 0.000125 or 0.0125% of the time, the song will be played exactly six out of seven days.
Every day represents a trial in this binomial probability issue, and there are only two potential results:
either the music is played (a success), or it is not (failure). We're looking for the likelihood that exactly 6 out of 7 trials will be successful.
The likelihood of success (performing the song) is 1/6, while the likelihood of failure (not playing the song) is 1 - 1/6 = 5/6, on any given day.
We can use the binomial probability formula to find the probability of exactly 6 successes in 7 trials:
P(6 successes) = (7 choose 6) * (1/6)⁶ * (5/6)¹
where (7 choose 6) is the number of ways to choose 6 days out of 7 to play the song, and is calculated as:
(7 choose 6) = 7! / (6! * 1!) = 7
Plugging in the values, we get:
P(6 successes) = 7 * (1/6)⁶ * (5/6)¹
P(6 successes) ≈0.00012502
Therefore, the probability that the song will be played on exactly 6 days out of 7 is approximately 0.000125 or 0.0125%.

Let us explain the meaning of rational number
A rational number is any number you can put it as a fraction
Ex: 2, 3.5, 15/4, ..........
It can not be an approximated number like 1.23435...... which means can not be exact number
Let us look to the choices to see which number can not be a rational number
2 + 2 = 4 it is rational number
5 + 2.7 = 7.7 it is rational number
\(\frac{2}{3}+\frac{1}{3}=1\)it is also a rational number
what about 10 + 0.998987.....?
Since 0.998987..... is not an exact number it is an approximated number
So 10 + 0.998987.... is not a rational number

4(1-x)<16 solve and graph
Answers
Answer: (x > -3).
Step-by-step explanation:
To solve the inequality 4(1 - x) < 16, we will simplify and solve for x:
4(1 - x) < 16
Distribute the 4:
4 - 4x < 16
Subtract 4 from both sides:
-4x < 12
Divide both sides by -4. Note that when dividing by a negative number, the inequality sign flips:
x > -3
The solution to the inequality is x > -3. This means that x must be greater than -3 for the inequality to hold true.
To graph the solution on a number line, we mark a shaded region to the right of -3, indicating that all values greater than -3 satisfy the inequality:
The open circle at -3 indicates that -3 is not included in the solution since the inequality is strict (x > -3).

Obesity is seen as a growing health problem in many countries, including the United States. To determine whether or not there has been an increase in obesity in men over the past ten years, medical records for 50 randomly sampled men from the year 2000 and for 75 randomly sampled men from the year 2010 were analyzed. Out of the 50 men from 2000, 10 were assigned as obese according to their height and weight while 30 out of the 75 men from 2010 were assigned as obese. Calculate the z-test statistic for this hypothesis test. Round your final answer to 2 decimal places
Answers
Answer:
The z-test statistic for this hypothesis test is \(z = 4.33\)
Step-by-step explanation:
Proportion in 2000:
10 of the 50 men were obese, so:
\(p = \frac{10}{50} = 0.2\)
Test if it has increased:
At the null hypothesis, we test if the prevalence of obesity has not increased, that is, the proportion is of 0.2 or less, so:
\(H_0: p \leq 0.2\)
At the alternative hypothesis, we test if this prevalence has increased, that is, the proportion is above 0.2. So
\(H_1: p > 0.2\)
The test statistic is:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
In which X is the sample mean, \(\mu\) is the value tested at the null hypothesis, \(\sigma\) is the standard deviation and n is the size of the sample.
0.2 is tested at the null hypothesis:
This means that \(\mu = 0.2, \sigma = \sqrt{0.2(1-0.2)} = 0.4\)
30 out of the 75 men from 2010 were assigned as obese.
This means that \(n = 75, X = \frac{30}{75} = 0.4\)
Value of the z-test statistic:
\(z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
\(z = \frac{0.4 - 0.2}{\frac{0.4}{\sqrt{75}}}\)
\(z = 4.33\)
The z-test statistic for this hypothesis test is \(z = 4.33\)

Which has a greater effect on the volume-changing the radius by a given amount or changing the height by the same amount? Why?
Answers
Answer: Changing the radius of an object by a given amount has a greater effect on the volume than changing the height by the same amount. The volume of a cylinder is given by the formula V = πr²h, where V is the volume, r is the radius, and h is the height. If we change the radius by a given amount, say x, the new radius would be r+x. Hence, the new volume would be V' = π(r+x)²h = π(r²+2rx+x²)h = V + 2πrxh + πx²h. We can see that the volume change equals 2πrxh + πx²h. The first term is proportional to both the radius and the height, whereas the second term is proportional to the square of the radius and the height. Assuming that the height change is also x, the new volume would be V'' = πr²(h+x) = V + πr²x. We can see that the volume change is proportional to the radius squared and the change in height. Therefore, changing the radius by a given amount has a greater effect on the volume than changing the height by the same amount.
