Answer:

5 $20 bills and 7 $10 bills

Step-by-step explanation:

You need to have 12 bills, and their values must add up to $170. Start with a guess, and adjust the guess until you find the answer.

The total number of $20 bills and $10 bills must be 10.

I made a table below. I started with a guess and kept adjusting it.

Number of          Number of          Total

$20 bills               $10 bills               Value

8   ($160)              4    ($40)              $200      Value is too high.

6   ($120)              6    ($60)              $180       Value is close

5   ($100)              7    ($70)               $70        Correct value

Answer: 5 $20 bills and 7 $10 bills

Answer:

x = 35

Step-by-step explanation:

40 + 2x + 2x = 180

Subtract 40 on both sides.

2x + 2x = 140

4x = 140

Divide with 4 on both sides.

x = 35

Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.
krok68 [10]

Answer:

Mean = 51.4.

Mode = 49.

Median = 52.

Range = 6.

Step-by-step explanation:

Mean = Sum of all observations / Number of observations.

Mean = (49+49+54+55+52+49+52)/7

Mean = 360/7

Mean = 51.4 (to the nearest tenth).

Mode = The most repeated values = 49 (repeated 3 times).

Range = Largest Value - Smallest Value = 55 - 49 = 6.

Median = The central value of the data.

First, arrange the data in the ascending order: 49, 49, 49, 52, 54, 55, 55.

It can be seen that the middle value is 52. Therefore, median = 52!!!
