1. Many of the continuous random variables that occur in real life are approximately normally distributed. How do you think this helps in studying real life variables?
2. Do you realize and understand the advantage of being able to convert values of an arbitrary normally distributed random variable to the corresponding values of the standard normal variable? If yes, list all the possible advantages of being able to do this. If not what do you plan to do to understand why the standard normal random variable is widely used for computations involving normal distributions?

jenny has $55 in her checking account, he bought 7 equally priced dvds and paid with a check. her new account balance is -$22. how much was each dvd?
Answer:
Jenny spent $11 on each dvd she bought.
Step-by-step explanation:
First and foremost, add 55 and 22 since her account balance is now at -$22 since that shows she spent even more.
55+22= 77
Next step divide 7 into 77 since that's how many dvds jenny bought.
77÷7= 11
The answer is $11. Jenny spent $11 on each dvd she bought.

Answer:
Clean and Bright
Step-by-step explanation:
For soapy suds, you would do 13×12, would would give you only 156 sq inches. However, with Clean and Bright, you would do 9×13×8 since it is three dimensional. This would give you 936 cubic inches, meaning it holds the most detergent.

The diagram shows the dimensions of a triangular prism what is the volume. Click on photo to see
Answer:
36 in^3
Step-by-step explanation:
1) find the area of the triangle
A = (leg 1 x leg2)/2 = (3 x 4)/2 = 6 in^2
2) find the volume
V = base area x height = 6 x 6 = 36 in^3
Salaries for various positions can vary significantly, depending on whether or not thecompany is in the public or private sector. The U.S. Department of Labor posted the2007 mean salary for human resource managers employed by the federal governmentas $76,503. Assume the annual salaries for this type of job are normally distributedand have a standard deviation of $8850.a)What is the probability that a randomly selectedhuman resource manager received over $100,000in 2007?
Answer:
0.0039 = 0.39% probability that a randomly selectedhuman resource manager received over $100,000 in 2007.
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 of 76503, standard deviation of 8850.
This means that [tex]\mu = 76503, \sigma = 8850[/tex]
a)What is the probability that a randomly selected human resource manager received over $100,000 in 2007?
This is 1 subtracted by the pvalue of Z when X = 100000. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{100000 - 76503}{8850}[/tex]
[tex]Z = 2.66[/tex]
[tex]Z = 2.66[/tex] has a pvalue of 0.9961
1 - 0.9961 = 0.0039
0.0039 = 0.39% probability that a randomly selectedhuman resource manager received over $100,000 in 2007.

Step-by-step explanation:
Duncan ran 26.2 miles in 4 hours 10 minutes. At this rate, rounded to the nearest tenth, how long did it take Duncan to run each mile?
Answer:
Time taken for cover 1 miles = 0.16 hour (Approx.)
Step-by-step explanation:
Given:
Total distance cover by Duncan = 26.2 miles
Time taken by Duncan = 4 hours 10 minutes
Find:
Time taken for cover 1 miles
Computation:
Time taken by Duncan = 4 hours 10 minutes
Time taken by Duncan = 4 + 0.167 hour
Time taken by Duncan = 4.167 hour
Speed = Distance / Time
Speed = 26.2 / 4.167
Speed = 6.28 miles/hour (Approx.)
So,
Time taken for cover 1 miles = 1/6.28
Time taken for cover 1 miles = 0.16 hour (Approx.)
Here is a table that shows students scores for 10 rounds of a video game. What is the median score?
145 is the median :)
Answer:
145
Step-by-step explanation:
130 + 150 + 120 + 170 + 130 + 120 + 160 + 160 + 190 + 140 = 1470
1470 ÷ 10 = 145
You buy a new backpack that costs $62.00. The sales tax is 6.5%. What is the total amount you need to pay, including tax?
Answer:
$66.03 in total.
Step-by-step explanation:
$66.03 because 6.5% is 0.065 and $62.00 times 0.065 equals $4.03. $62.00 plus $4.03 is $66.03.

Answer:
d) 72/100
Step-by-step explanation:
the first grid is 42/100 so you add the 3/10 which 3/10 is equal to 30/100 the grid is just simplified. Once you add 42/100 and 30/100 it equals to 72/100. Hope this is helps you !
Answer:
72/100

4 tran ra To make cherry trail mix, Sebastián needs 4 oz of nuts for every 3 oz of dried cherries. To make sunflower trail mix, he needs 5 oz of nuts for every 2 oz of sunflower seeds. Can Sebastián make more cherry trail mix or sunflower trail m with 20 oz of nuts? Show your work. OLUTION metale to make bronz bronz
For starters I am not 100% sure of if this is correct I may not understand the quest so bare with me
Answer:
Cherry Trail Mix
Step-by-step explanation:
4 oz of nuts for every 3 oz of dried cherries
5 oz of nuts for every 2 oz of sunflower seeds
- Multpy the amount of nuts in each bag to 20 - Cherry Trail Mix: 4*5=20
Sunflower Trail Mix: 5*4=20
- Now multiply the amount of dried cherries and sunflower seeds by the number used to get to 20
Cherry Trail Mix: 3*5= 15 Sunflower Trail Mix: 2*4=8
- Now add up the amount of oz in each
Cherry: 20+15=35
Sunflower: 20+8=28
35oz > 28oz

The following is an estimated demand function: Q = 875 + 6X +15Y − 5P Where Q is quantity sold, X is advertising expenditure (in thousands of dollars), Y is income (in thousands of dollars), and P is the good's price. The R2 was 0.92; the F-statistic was 57; the Standard Error of the Estimate (SEE) is 25. In the above regression: A. income has the highest importance in predicting sales. B. all of the options. C. the regression model is capable of explaining 92% of sales. D. if price increases 10 dollars, the sales will decrease 50.
Answer:
See step by step explanation
Step-by-step explanation:
Q = 875 + 6 * Adv. expenditure + 15* Income - 5 * Product price
A.- As we can see each unitary change (in thousands of $) in Income, will mean an increase of 15 $ (thousands ) in the demand function, the highest impact in Q
C.- The regression model is capable of explaining 92 % of the variation in Q due to the predictors.
D.- If the price is increased by 10 $ demand will decrease in 50
