Using the Central Limit Theorem, it is found that none of the samples satisfy the normal condition.
What does the Central Limit Theorem state?It states that the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex], as long as at least one of these following conditions is respected.
The underlying distribution is normal.The sample size is greater than 30.In this problem, the underlying distributions are skewed, and both sample sizes are less than 30, hence none of the samples satisfy the normal condition.

Answer:
X+Y=26
X-Y=12
Step-by-step explanation:
fiction books= X
non fiction books= Y
then,
fiction books= X
non fiction books = X-12
but Y= X - 12
from. the statement,
X+Y = 26

A bag contains 7 red, 3 yellow, and 4 blue marbles. What is the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first?
A) 11/14
B) 1/7
C) 2/13
D) 75/91
Answer:
2/13
Step-by-step explanation:
4/14 × 7/13 when i simplify it becomes 2/13!!!
The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.
What is Probability?Probability helps us to know the chances of an event occurring. The sum of all the probabilities of an event is always equal to 1. The formula for probability is given as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
The probability of getting a blue marble at the first try is,
Probability(Blue) = Number of blue marbles / Total number of marbles
= 4 / 14
The probability of getting a red marble at the second try is,
Probability(Red) = Number of Red marbles / Total number of marbles
= 7 / 13
The probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is,
Probability = Probability(Blue) × Probability(Red)
= (4/14) × (7/13)
= 2/13
Hence, the probability of pulling out a blue marble, followed by a red marble, without replacing the blue marble first is 2/13.

The credit card industry works similar to the cigarette industry. what reasons caused culture to change its view of cigarettes over the past few decades? what do you think would need to happen to change america's view of credit cards?
The credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.
What is credit card?A credit card is a sort of payment card that uses a line of credit rather than the account holder's cash deposits to make purchases.
Tobacco use can have a negative impact on personal finances due to the sheer high price of tobacco products, wasted pay owing to sickness absence, plus hospitalization rates due to the higher risk of illness associated with smoking use.
If you let that debt grow, you may find that the amount of interest you owe equals or even exceeds your original principal, forcing you to spend a lot just to pay it off.
Thus, the credit card industry and cigarette industry are very similar in terms of negative influence on personal finances.

Avery bought stock in a company two years ago that was worth x dollars. During the first year that she owned the stock, it increased by 40%. During the second year the value of the stock decreased by 10%.
Answer:
The value of the stock can be found by: x × 1.26.
Step-by-step explanation:
The value of the stock in year one can be found by multiplying x by 1.4. This will represent a 40% increase in value. The following year, the stock decreases in value by 10%; this is represented by multiplication by 0.9. For example, if the value of the stock was $5:
5 × 1.4 = 7 (A 40% increase in value)
(5 × 1.4) * 0.90 = 6.3 (A further 10% decrease in value)
Rather than writing out the long version, we can simplfify by multiplying 1.4 by 0.9 to get 1.26 .We can also replace 5 with x to get a more general equation.

The slope of the line through ( -2 , -5 ) and ( -6 , 7 ) is -3

Mrs. Welloff has just passed away, she has a $1,000,000 life insurance policy and her beneficiaries are her son and 3 grandchildren. She will leave 50% of her estate to her son and the other 50% to her three grandchildren equally. How much money will they each receive?
Son_______________
Grandchild #1_______________ Grandchild #2_______________ Grandchild #3_______________
Answer:
Step-by-step explanation:
1/2 of 1,000,000 is 500,000
the son will get 500,000$
now 500,000 divided by 3(since it's 3 grandkids) is
166666.66, because it's money, and you have to round to the nearest cent.
one will get 166666.67, but it doesn't matter who.
so
grand #1 = 166666.66$
grand #2 = 166666.66$
grand #3 = 166666.67$

(b) How many hours each day does Juliet spend coaching each sport?
Show your work. Be sure to label appropriately.
An equation is formed of two equal expressions. Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.) Let the amount of time spent on soccer be represented by y, while the amount of time spent on softball is represented by x. Therefore, we can write,
x+y=18
y=2x+1.5
Hence, the system of equations to model the situation is x+y=18 and y=2x+1.5.
B.) Substitute the value of y from the second equation in the first equation, therefore,
x+y=18
x+2x+1.5=18
3x = 16.5
x = 5.5 hours
Substitute the value of x in the second equation, we will get,
y=2x+1.5
y=2(5.5)+1.5
y=11+1.5
y=12.5 hours
Hence, Juliet teaches softball for 5.5 hours, while she teaches football for 12.5 hours.

describe the transformations from the parent function f(x)=x2 to the function g(x)=(x-2)^2+5
A. 2 units down, 5 units to the left
B. 2 units down, 5 units to the right
c. 2 units to the right, 5 units up
D. 2 units to the left, 5 units up
Answer:
C.) 2 units to the right, 5 units up
Step-by-step explanation:
The graph shifts left or right when a number modifies the "x" value before it is affected by any other number/function in the equation. This number is within parentheses with the "x". Subtracting a value moves the function to the right, whereas adding a value moves the function to the left. Therefore, since 2 is being subtracted from "x", the function has been shifted 2 units to the right.
The graph shifts up or down when the y-intercept changes. The y-intercept is the "b" value in a standard function. You can identify this value by plugging in zero to "x". If this number is positive, the function is shifted upwards, and if this number is negative, the function is shifted downwards. Therefore, since there is a 5 added to the equation, the function is shifted 5 units up.
