Answer:
1028.5 is the mean
Answer:
481.75
Step-by-step explanation:
To find the mean add up all the numbers in the data set :
8 + 445 + 276 + 1198 = 1927
divide the numbers by how many numbers are in the data set :
1927 ÷ 4 = 481.75
Therefore, the mean in the data set 481.75
Eric is a car salesman. He earns a weekly salary of $175 plus 4% commission on sales. This
week he sold a car for $35,450.
A) How much commission did he earn this week?
B) What did he earn in TOTAL this week?
Answer:
A) 141.8 B) 316.8
Step-by-step explanation:
I did 35.450k/100x4 to get 141.8. Then I did 175+141.8
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

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.

Mrs. James selected 4 3/4
pounds of grapes. The grapes
cost $2.50 per pound. How
much will Mrs. James pay for
the grapes?
A) $7.25
B) $11.88
C) $10.75
D) $16.50
PLEASE HELP
Answer:
B. $11.88
Step-by-step explanation:
4 · 2.50 = $10
3/4 · 2.50/1 = about $1.88
10 + 1.88 = $11.88
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?

Help me please!!!!! I need help with angles
Answer:
<CFE = 28
<RPQ = 53
Step-by-step explanation:
1)
<CFE + 152 = 180
<CFE = 180 - 152
<CFE = 28
2)
Complementary means the angles add up to 90 so:
<RPQ + 37 = 90
<RPQ = 90 - 37
<RPQ = 53
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.)

Answer:
32, 16, 8, 4, 2, 1
Explanation:
The geometric mean can be represented by [tex] \sqrt[n]{x_{1} • x_{2} • x_{3} • .. x_{n}} [/tex].
Which is the mean of the product of n numbers, used to find the average of a geometric progression.
Don't get confused by geometric mean, it is only asking you about the next numbers in the geometric sequence given the first and sixth term.
The explicit rule for a geometric sequence can be modeled by:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
Where [tex] a_{n} [/tex] is the nth term, [tex] a_{1} [/tex] is the first term in the sequence, n is the term number, and r is the common ratio.
Since we already know the first term, [tex] a_{1} [/tex] will simply be 32.
Since we know it's geometric, there will be an exponential relationship, which means that we will use the geometric mean to find the common ratio.
There are 6 total terms, r is raised to the n – 1 so 6 – 1 = 5, and that will be the degree of this root.
[tex] \sqrt[5]{\frac{a_{6}}{a_{1}}} [/tex] =
[tex] \sqrt[5]{\frac{1}{32}} [/tex] =
[tex] \frac{1}{2} [/tex].
Therefore: [tex] r = \frac{1}{2} [/tex].
Using all the information we have, we can find the explicit rule:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
[tex] a_{1} [/tex] = 32[tex] r = \frac{1}{2} [/tex][tex] a_{n} = a_{1} • r^{n-1} [/tex] →
[tex] \boxed{a_{n} = 32 • (\frac{1}{2})^{n-1}}[/tex]
________________________________
We can test that this works by substituting the number location of the term you want to find.
For instance:
[tex] a_{1} = 32 • (\frac{1}{2})^{1-1} [/tex]
[tex] a_{1} = 32 • (\frac{1}{2})^{0} [/tex]
[tex] a_{1} = 32 • 1[/tex]
[tex] a_{1} = 32 [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{6-1} [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{5} [/tex]
[tex] a_{6} = 32 • \frac{1}{32} [/tex]
[tex] a_{6} = 1 [/tex]
List the following rational numbers in order from least to greatest -1/2, 2.5, -8 1/4,
1 1/2,-1.5,3
Answer:
-8, -1.5, 1/2, 1/4, 1/2, 1, 2.5, 3
Step-by-step explanation:
Answer:
-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2 (if is not 11/2 but 1 and 1/2) the answer is : -8, -1.5 , -1/2 , 1/4 , 1/2, 1 , 2.5, 3
Step-by-step explanation:
First of all we have to express the decimal numbers with a fraction
2.5 = 25/10 = 5/2
-1.5 = -15/10 = -3/2
now we have to express al numbers with a fraction with the same denominator. In this case the value that help us the most is 4
-1/2 = -2/4
5/2 = 10/4
-8 = -32/4
1/4 = 1/4
11/2 = 22/4
-3/2 = -6/4
3 = 12/4
now we have to check only the numerators for discover the order of the numbers. So from the least to the greatest we have:
-32/4 ; -6/4 ; -2/4 ; 1/4 ; 10/4 ; 12/4 ; 22/4
the final step is rewrite the original numbers in this order
-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2

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.
