The carousel at a local theme park has a diameter of 32 feet. each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute. what is the maximum distance riders travel in one full ride? round to the nearest hundredth.
Answer:
1297.37 feet.
Step-by-step explanation:
Given:
The carousel at a local theme park has a diameter of 32 feet.
Each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute.
Question asked:
What is the maximum distance riders travel in one full ride? Round to the nearest hundredth.
Solution:
First of all we will find the radius of the carousel:-
Diameter = 32 feet
Radius, r = [tex]\frac{Diameter}{2} =\frac{32}{2} =16\ feet[/tex]
Now, we will find distance covered by the carousel in one ride that means its circumference;
[tex]Circumference\ of \ the \ circle=2\pi r[/tex]
[tex]=2\times\frac{22}{7} \times16\\ \\ =\frac{704}{7} \\ \\ =100.571\ feet[/tex]
In 1 minute, number of revolution taken by carousel = 4.3
As each ride last for 3 minutes:-
In 3 minutes, number of revolution taken by carousel = 3 [tex]\times[/tex] 4.3 = 12.9
In 1 revolution, distance covered by carousel = 100.571 feet
In 12.9 revolution, distance covered by carousel = 100.571 [tex]\times[/tex] 12.9
= 1297.365 feet
Thus, the maximum distance riders travel in one full ride is 1297.37 feet.

A division of a company has over 200 employees, 40% of which are male. Each month, the company randomly
selects 8 of these employees to have lunch with the CEO.
What are the mean and standard deviation of the number of males selected each month?
You may round your answers to the nearest tenth.
mean:?
males
standard deviation:?
males
Answer:
mean: 3.2 standard deviation: 1.4
Step-by-step explanation:
its correct
The mean number of males selected each month is 3.2, and the standard deviation is approximately 1.4 males.
Explanation:The student's question is about finding the mean and standard deviation of the number of males selected each month to have lunch with the CEO in a division of a company. Given that 40% of the employees are male, we can determine the mean number of males selected for the lunch by multiplying the percentage of males by the number of employees selected each month, this is known as the expected value, E(X) = np. Since 40% of over 200 employees are male, we assume we have at least 80 males (0.40 x 200) in the division. If 8 employees are selected at random, the mean number of males expected, μ, would be 40% of 8, or 3.2 males.
To find the standard deviation, σ, we use the formula for the standard deviation of a binomial distribution, which is σ = sqrt(np(1-p)), where p is the probability of choosing a male (0.40) and n is the total number selected (8). In this case, the standard deviation is σ = sqrt((8)(0.40)(0.60)) and rounding to the nearest tenth gives us σ ≈ 1.4.
HELP ASAP!!! A bag contains 5 red raffle tickets, 7 blue raffle tickets and 2 green raffle tickets. Jackie will randomly select a raffle ticket from the bag 3 times. She will replace it each time. What is the probability that she selects a green ticket on her first two selections and a red ticket on her third selection?
Answer:
5/168
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome.
According to the question, if the bag contains 5 red raffle tickets, 7 blue raffle tickets and 2 green raffle tickets, the total number of ticket is given as:
5+7+2 = 14tickets
The total outcome = 14.
If Jackie selects a green ticket on her first two selections, the probability of selecting a green twice from the bag and replacing it will be 2/14×2/14 = 4/48.
Note that the total number of ticket remains complete each time she selects since the ticket was always REPLACED.
If Jackie picks a red on her third selection, the probability of picking a red will be 5/14.
The probability that she selects a green ticket on her first two selections and a red ticket on her third selection will then be:
= 4/48 × 5/14
= 1/12×5/14
= 5/168
Answer:
5/686
Step-by-step explanation:
Red raffle tickets=5
Blue raffle tickets=7
Green raffle tickets= 2
Total raffle tickets=14
Three tickets were selected randomly with replacement
Probability of selecting Green tickets on her first two selections and red tickets on her third selection =propability of selecting Green raffle tickets twice and red raffle tickets once
=2/14×2/14×5/14
=1/7×1/7×5/14
=1/49×5/14
=5/686
Note: There are two green tickets and since it is selected with replacement, the total green tickets and the total raffle tickets doesn't change.

What is the most frequent number of children in a household in Cam's neighborhood?
Answer:
0
Step-by-step explanation:
The answer is 0. It shows up the most on the list. Also I know the awful Khan Academy brought you here.
The most frequent number of children in household is given by the mode and M = 0
What is Mode?The mode in statistics refers to a number in a set of numbers that appears the most often. Place all numbers in a given set in order; this can be from lowest to highest or highest to lowest, and then count how many times each number appears in the set. There are two types of modes
Multimodal and Bimodal
Given data ,
To find the most frequent number of children in a household in Cam's neighborhood, we can use a frequency table to count how many times each number appears in the data set:
A = 0, 0, 2, 1, 2, 8, 3, 0, 0
From the frequency table, we can see that the most frequent number of children in a household is 0, which appears 3 times in the data set.
And , the mode of the data set is M = 0
Therefore, the most frequent number of children in a household in Cam's neighborhood is 0.
Hence , the mode M = 0

write an expression that is equivalent to 7 3/4 + 1 3/4 - 3 5/6 that uses addition instead of subtraction
Answer:
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6
Step-by-step explanation:
7 3/4 + 1 3/4 - 3 5/6
we do not want the minus sign.
7 3/4 + 1 3/4 - 3 5/6 = 7 3/4 + 1 3/4 - 3 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 7+ 3/4 + 1 + 3/4 - 3 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 7 + 1 - 3 + 3/4 + 3/4 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 5 + 3/4 + 3/4 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1 - 5/6
7 3/4 + 1 3/4 - 3 5/6 = 4 + 3/4 + 3/4 + 1/6
To rewrite the expression 7 3/4 + 1 3/4 - 3 5/6 using addition instead of subtraction, we can change the sign of the subtraction term and find the common denominator to add the fractions.
Explanation:To rewrite the expression 7 3/4 + 1 3/4 - 3 5/6 using addition instead of subtraction, we can change the subtraction to addition by changing the sign of the second term. So the expression becomes:
7 3/4 + 1 3/4 + (-3 5/6)
Now, to add fractions with different denominators, we need to find the common denominator. In this case, the common denominator is 12.
Converting all the fractions to have a denominator of 12, we get:
7 9/12 + 1 9/12 + (-3 10/12)
Adding the numerators, we have:
7 + 9 + 1 + 9 - 3 - 10 = 13
So the expression 7 3/4 + 1 3/4 - 3 5/6, using addition instead of subtraction, is equal to 13.
A fuel tank has a volume of 36 gallons. When filled with biodiesel, it provides 4,500,000 BTUs. How many BTUs does 1 gallon of biodiesel yield?
Answer: 125,000 BTUs
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
A fuel tank has a volume of 36 gallons. When filled with biodiesel, it provides 4,500,000 BTUs
So, the proportion is:
36 gallons / 4,500,000 BTUs
For 1 gallon
1 gallon / x BTUs
36/4,500,000 = 1/x
Solving for x:
x = 1 / (36/4,500,000)
x = 125,000 BTUs

Which of the following is a step used in the construction of an equilateral triangle inscribed in a circle?
Connect all six points on the circle.
Draw two line segments connecting the points where the arc intersects the circle and an endpoint of the diameter.
Construct two diameters using the points where the arc intersects the circle and the center.
Connect the endpoints of the two diameters
Final answer:
To construct an equilateral triangle inscribed in a circle, the correct steps are to construct two diameters using the points where the arc intersects the circle and the center, and then connect the endpoints of the two diameters.
Explanation:
The correct step used in the construction of an equilateral triangle inscribed in a circle is to construct two diameters using the points where the arc intersects the circle and the center. This will create a cross shape inside the circle. Then, you connect the endpoints of the two diameters to form the equilateral triangle. This is because the lengths of the radii of the circle are equal, and connecting the points where the arc intersects the circle with the center creates two congruent radii.
