- Max can read about 150 words per minute. Unfortunately for Max, he has waited until
this weekend to do all his reading. The book he has to read is 310 pages long. If a typical
paperback has about 350 words per page, how many hours should he set aside for this
reading?
A. 12 days
B. 12 hours
C. 72.3 days
D. 610 hours
Answer:
B) 12 hours
Explanation
Max can read 150 words per minute. 350 words per page divided by 150 is 2.333, so max can read 1 page in around 2 minutes. There are 310 pages. 2.333 * 310 is around 723. 723 minutes converted to hours is 12 hours. Boom. Done.

A study of drive-thru wait times for fast-food restaurants found that the average time spent Wendy's drive-thru was 138.5 seconds. Assume that drive-thru wait times are normally distributed with a standard deviation of 29 seconds, A Wendy's owner wants to give a free Frosty to customers who have an unusually long wait in the drive-thru.
The length of time the owner should choose so that only 0.75% of customers get a free Frosty i.e. only 0.75% wait longer than ________ seconds) is _________ seconds (give your answer to 2 decimal places).
Answer:
207.72 seconds.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean waiting time of 138.5 seconds, standard deviation of 29 seconds.
This means that [tex]\mu = 138.5, \sigma = 29[/tex]
The length of time the owner should choose so that only 0.75% of customers get a free Frosty i.e. only 0.75% wait longer than
The 100 - 0.75 = 99.15th percentile, which is X when Z has a pvalue of 0.9915, so X when Z = 2.387.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.387 = \frac{X - 138.5}{29}[/tex]
[tex]X - 138.5 = 2.387*29[/tex]
[tex]X = 207.72[/tex]
So the answer is 207.72 seconds.

The function g is defined as follows.
g(x) = 2x²+7
If the graph of g is translated vertically downward by 5 units, it becomes the graph of a function h.
Find the expression for h(x).
x
Answer:
h(x) = 2x²+2
Step-by-step explanation:
Given the function g is defined as follows.
g(x) = 2x²+7
If the graph is translated by 5units vertically downwards, this means that the function will be reduced by 5 units to have;
h(x) = 2x²+7 - 5
h(x) = 2x²+2

4. Tori bought x shares of Mattel stock for m dollars per share. She sold
all of the shares months later for y dollars per share. Express her cap-
ital gain or loss algebraically.
Answer:
mx = y
or
y = mx
Step-by-step explanation:
If she pays m per share, and x represents each share, you will multiply m and x. If she sold all them for the value of y. Then you set mx equal to y.
mx = y
or
y = mx

The weight of a bass varies jointly as its girth and the square of its length (Girth is the distance around the body of the fish.) A prize-winning bass weighed in at 21.8 lb and
measured 33 in long with a 19-in girth. How much to the nearest tenth of a pound) would a bass 34 in long with a 21-in girth weigh?
The bass would weigh approximately
(Do not round until the final answer. Then round to the nearest tenth as needed.)
The new girth is 22 inches; the reference girth is 20 inches. The weight is proportional to the girth, so the reference weight will get multiplied by 22/20 = 11/10.

You invest $2,000 in an investment that pays an annual interest rate of 7.5% with monthly compounding. How many months will it take for your investment to be worth $3,500
Answer:
10 years
step-by-step explanation:
First, divide 7.5 by 100, you should get 0.075, then multiply 0.075 by 2000, you should get 150, thats how much interest he gains each year, now subtract 2000 from 3500 to see how much he needs to get to 3500, you should get 1500, now divide 1500 by 150, you should get 10, which is how many years he will need to get to 3500 from 2000

Which expression is equivalent to 64y18 – 1000z6?
Answer:
8 * (2y⁶ - 5z²) ( 4y¹² +10 y⁶z² + 25z⁴)
Step-by-step explanation:
64y¹⁸ – 1000z⁶ = 8 * (8y¹⁸ - 125z⁶) = 8 * ((2y⁶)³ - (5z²)³)
= 8 * (2y⁶ - 5z²) ( 4y¹² +10 y⁶z² + 25z⁴)

A carnival game has 150 rubber ducks floating in a pool. The person playing
the game takes out one duck and looks at it.
• If there's a red mark on the bottom of the duck, the person wins a small
prize.
Many ducks do not have a mark.
After 50 people have played the game, only 3 of them have won a small
prize.
Estimate the number of the 150 ducks that you think have red marks on
the bottom.
Answer:
Pretty sure it's 17 ducks.
The correct answer is based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.
To estimate the number of ducks with red marks on the bottom, we can use the information given: out of 50 people playing the game, only 3 have won a small prize.
We can assume that the probability of winning a small prize is the same for each player, and that each duck is equally likely to have a red mark.
If only 3 out of 50 people have won a small prize, we can estimate that the probability of winning is approximately 3/50.
Let's denote the number of ducks with red marks as "x." The probability of winning a small prize can be represented as x/150 (since there are 150 ducks in total).
Setting up the equation:
x/150 = 3/50
To solve for x, we can cross-multiply:
50x = 3 * 150
50x = 450
Dividing both sides by 50:
x = 9
Therefore, based on the information given, we can estimate by probability that there are approximately 9 ducks with red marks on the bottom out of the 150 ducks in the pool.
