Answer:

(A) 6/20 = x/2000

Step-by-step explanation:

To complete your questions, the missing parts are shown below

                   Sample 1                  Sample 2        total

Country            5                               3                 8  

Pop                  4                                3                 7

Classical          3                                5                 8

Jazz                 2                                4                  6

Rock                6                                5                11

Total                20                               20             40

The proportion that would predict the number of jazz songs that Mr. McElroy has stored on his MP3 player is given by 6/20

Hence, our required proportion would be

6/20 =x/2000

We cross multiply  

20x = 2000 x 6

20x = 12000

Divide both sides by 20

X = 12000/20

X = 600

Hence, our required proportion would be

6/20 = x/2000

Two mechanics worked on a car. The first mechanic worked for
Temka [501]
Write a system of equations:

x + y = 125

20x + 15y = 2100

Solving:

x = 125 - y

20(125 - y) + 15y = 2100
2500 - 20y + 15y = 2100
2500 - 5y = 2100
-5y = 2100 - 2500
-5y = -400
y=80

x + 80 = 125
x = 125 - 80
x = 45

The first charges 45$ per hour and the second charges 80$ per hour

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist
maw [93]

Answer:

<em>The percent error of the cyclist's estimate is 5.63%</em>

Step-by-step explanation:

<u>Percentages</u>

The cyclist estimates he will bike 80 miles this week, but he really bikes 75.5 miles.

The error of his estimate in miles can be calculated as the difference between his estimate and the real outcome:

Error = 80 miles - 75.5 miles = 4.5 miles

To calculate the error as a percent, we divide that quantity by the original estimate and multiply by 100%:

Error% = 4.5 / 80 * 100 = 5.625%

Rounding to the nearest hundredth:

The percent error of the cyclist's estimate is 5.63%
