Drew works at a laundromat. Every day for two weeks, he records the total number of loads of laundry washed at the laundromat. T

Afina-wow [57]

Answer:

Step-by-step explanation:

The first quartile of his data is 60.

The median of his data is 82.

The first quartile Q1 is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.

The median Q2 is the median of the data set. This means that about 50% of the numbers in the data set lie below Q2 and about 50% lie above Q2.

Between Q1 and Q2 lie exactly 25% of the numbers in the data set.

25% of 200 is exactly 50, so option B is true.

2x-y=10 y=-4x+2 substitution method

AlladinOne [14]

Answer:

the solution is (2, -6)

Step-by-step explanation:

Substitute the second equation into the first, replacing y in the first:

2x - (-4x+2) = 10

Simplifying, we get:

2x + 4x - 2 = 10, or:

6x = 12, which yields x = 2.

Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6

Then the solution is (2, -6).

Answer:

Step-by-step explanation:

You can use a graphing calculator like desmos or draw your own graph to figure this out. Start by graphing each of those points. Then count the width and height. Multiply them to get the area. The width and height of the rectangle were 6 and 8, so the area is 48
