The following data shows the number of music shows 20 students of a class watched in a month:
3241004551 [841]

Answer:

The 2nd one.

Step-by-step explanation:

First, put the numbers in order from least to greatest. This isn't required, but it makes it easier.

3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20

Then, for each range of shows watched (0-5, 6-11, etc.) from the graph, count how many numbers from the list fit into that range.

Use the process of elimination:

In 3 4 4 4 4 4 4 4 7 7 8 9 10 10 13 13 19 19 19 20, numbers from 0-5 show up 8 times, so you can rule out the last 2 graphs. Numbers 12-17 show up 2 times, so the first one is incorrect. That leaves you with the second histogram.

Stephanie had a total of 80 pieces of $ 2 and $ 10 notes. After spending 2/5 of her $ 2 notes and 8 pieces of her $ 10 notes, sh
Ghella [55]

Answer:

$440

Step-by-step explanation:

notes $2 - n

notes $10 - m

n + m = 80 ----------> m = 80 - n

1 - 2/5 = 3/5

\frac{3}{5} * n = m - 8

\frac{3}{5} * n = 80 - n - 8 \\\\\frac{3}{5} * n + n = 72\\\\\frac{8}{5} * n = 72\\n = 45 \\m = 35\\

45 * $2 + 35 * $10 = 90 + 350 = $440
