A business owner needs to hire a cleaning service for the office. The cleaning company charges $250 for 5 rooms. The office has 12 rooms. An employee did the following math to determine the total cost to clean the office.
Step 1: $250 ÷ 5 rooms = $50 per room
Step 2: $50 × 12 rooms + $250 = $850
The total cost to clean the office is $850.
What was the employee’s error?
Step 1 should have been 5 rooms ÷ $250 = 0.02 rooms per $1.00.
Step 1 should have been $250 – 5 rooms = $245 per room.
Step 1 should have been $250 × 5 rooms = $1,250 per room.
Step 2 should have been $50 × 12 rooms = $600.
Step 2 should have been $50 + $250 = $300.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2

brainliest? ?

here try this one

3a-24=0
