Naya [18.7K]3 years ago
8 0

Answer:

The answer is option 3.

Step-by-step explanation:

First, you have to get rid of brackets by expanding :

14x + 3(x - 10)

= 14x + 3(x) + 3(-10)

= 14x + 3x - 30

Next, you have to collect like terms :

14x + 3x - 30

= 17x - 30

Jack and Jim sign up with an online music store. Jack chooses 15 downloads for $19.75, and Jim chooses 40 downloads for $43.50.
lina2011 [118]
The answer would be A. <span>The registration fee is $5.50, and the cost per download is $0.95.</span>

Solution
Let x = registration fee
y = cost/downloads

Jack
15y + x = 19.75 ; x = 19.75 - 15y
Jim
40y + x = 43.50

Thus,
40y + x = 43.50
40y + <span>19.75 - 15y = 43.50
</span>25y = 23.75
y= 0.95

for x,
<span>x = 19.75 - 15y</span>
x = 19.75 - 15( 0.95)
x= 19.75 -14.25
x = 5.5

A) The IQR is Q3 - Q1 Q3 is the right edge of the blue box and Q1 is the left edge.

IQR = 25-1 = 24

B) Median values are the line inside the blue boxes:

20-5 = 15

C) the male distribution is asymmetrical and the female distribution is more symmetrical. Because the men are asymmetrical it would be best to describe the distribution using the Median. The women are symmetrical so it would be best to use the mean.

Overall the mean is the most popular/ best way to measure the center.

D) the outlier could be the first day the movie was shown
