A physical education class has 21 boys and 9 girls. Each day, the teacher randomly selects a team captain. Assume that no student is absent. What is the probability that the team captain is a girl two days in a row?The probability of choosing a captain that is a girl two days in a row is
9
%.

Answers

The probability of choosing a captain that is a girl two days in a row is 9%

How to determine the probability?

The given parameters are:

Boys = 21

Girls = 9

The total number of students is

Total = 21 + 9

Total = 30

This means that the probability of selecting a girl is:

P(Girl) = 9/30

For two days, the required probability is

P = 9/30 * 9/30

Evaluate

P = 9%

Hence, the probability of choosing a captain that is a girl two days in a row is 9%

Answer:

2022: 33.19

2023: 35.18

2024: 37.29

Explanation:

The given equation to find the ticket price is

$y=0.5(1.06)^x$

Where x is the number of years after 1950.

So, to find the price for 2022, 2023 and 2024, we need to replace x by 72, 73 and 74 respectively because

2022 - 1950 = 72

2023 - 1950 = 73

2024 - 1950 = 74

Then, the price for each year is

$\begin{gathered} 2022\colon y=0.5(1.06)^(72) \n y=0.5(66.37) \n y=33.19 \n 2023\colon y=0.5(1.06)^(73) \n y=0.5(70.36) \n y=35.18 \n 2024\colon y=0.5(1.06)^(74) \n y=0.5(74.58) \n y=37.29 \end{gathered}$

Which of the following statements is not true? A. If the probability of an event occurring is 1.5, then it is certain that event will occur. B. If the probability of an event occurring is 0, then it is impossible for that event to occur.

Answers

Answer:

Therefore, we conclude that the statement in (A) is incorrect.

Step-by-step explanation:

We have the following sentences:

A) If the probability of an event occurring is 1.5, then it is certain that event will occur.

B) If the probability of an event occurring is 0, then it is impossible for that event to occur.

We know that the range of probability of an event occurring is in the segment [0, 1]. In statement under (A), we have the probability that is equal to 1.5.

Therefore, we conclude that the statement in (A) is incorrect.

Answer:

z = -ln│5eᵗ + C│

Step-by-step explanation:

dz/dt + 5eᵗ⁺ᶻ = 0

dz/dt = -5eᵗ⁺ᶻ

dz/dt = -5eᵗeᶻ

-e⁻ᶻ dz = 5eᵗ dt

e⁻ᶻ = 5eᵗ + C

-z = ln│5eᵗ + C│

z = -ln│5eᵗ + C│

The side length of a square is 5 feet. A. What is the perimeter of the square? B. What is the area of the square?

Answers

Answer:

A. 20 B. 25

Step-by-step explanation:

A. Perimeter equals the all the side lengths added together, so 5+5+5+5=20

B. Area equals (for a square) two side lengths multiplied by one another, so 5x5=25

A study is being conducted to compare the average training time for two groups of airport security personnel: those who work for the federal government and those employed by private security companies. From a random sample of 12 government-employed security personnel, average training time was 72 hours, with a sample standard deviation of 8 hours. In a random sample of 16 privately employed security personnel, training time was 65.4 hours, with a sample standard deviation of 12.3 hours. Assume that training time for each group is normally distributed. Use the following notations:μ1: The mean training time for the population of airport security personnelemployed by the federal government.μ2: The mean training time for the population of airport security personnelemployed by private security companies.The goal of the statistical analysis is to determine whether the sample data support the hypothesis that average training time for government-employed security personnel is higher than those employed by private security companies.1.
