The discount was 12 dollars off. You first subtract $530 from $650 & you'll be left with $120 . Then since it was you and 9 friends, that's a total of 10 people. So you divide 120 by 10 . Leaving you with the answer : $12 off which is the discount.

Use the standard deviation values of the two samples to find the standard deviation of the sample mean differences.

larisa86 [58]

The standard deviation of the sample mean differences is 4.854

<h3>How to determine the standard deviation of the sample mean differences?</h3>

The table of values is given as:

<u>Sample Standard deviation</u>

Red box 3.868

Blue box 2.933

The standard deviation of the sample mean differences is calculated using:

$\sigma = \sqrt{\sigma_1^2 + \sigma_2^2}$

This gives

$\sigma = \sqrt{3.868^2 + 2.933^2}$

Evaluate the expression

$\sigma = 4.854$

Also, the table of value do not give any information regarding the sample size.

This means that the sample size of the session regarding the number of people would purchase the red box and the blue box are unknown

Hence, the standard deviation of the sample mean differences is 4.854

One month Tammy rented 2 movies and 6 video games for a total of $ 42 . The next month she rented 5 movies and 3 video games for

jeka94

Answer:

The rental cost of one movie is $2.25 and the rental cost of one video game is $6.25

Step-by-step explanation:

Let the rental cost of 1 movie be m.

Let the rental cost of 1 video game be v.

One month, Tammy rented 2 movies and 6 video games for a total of $42. This means that:

2m + 6v = 42 ________ (1)

The next month she rented 5 movies and 3 video games for a total of $30. This means that:

5m + 3v = 30 _________(2)

We now have two simultaneous equations:

2m + 6v = 42 ________ (1)

5m + 3v = 30 _________(2)

Multiply (2) by 2, and we have:

2m + 6v = 42 __________ (1)

10m + 6v = 60 _________ (3)

Subtract (1) from (3):

10m + 6v = 60

-<u> 2m + 6v = 42</u>

=> m = 18 / 8

m = $2.25

Put the value of m back in (1):

2(2.25) + 6v = 42

4.5 + 6v = 42

=> 6v = 42 - 4.5 = 37.5

v = 37.5 / 6

v = $6.25

Therefore, the rental cost of one movie is $2.25 and the rental cost of one video game is $6.25
