Answer:
42
Step-by-step explanation:
The stem and leaf plot represent the list of numbers:
- 15, 18, 46, 50, 50, 50, 50, 57
The mean of a data set is commonly known as the average. You find the mean by taking the sum of all the data values and dividing that sum by the total number of data values.
The formula for the mean of a population is
The formula for the mean of a sample is
Both of these formulas use the same mathematical process: find the sum of the data values and divide by the total. For the data values entered above, the solution is:
50.24 rounded to the nearest tenth is 50.2
Since the 4 is less than 5, it can't round the 2 up to 3. The 2 would stay the same.
The answer is B hopefully this helped

All you had to do was line them up from lowest to highest.
Answer:
Step-by-step explanation:
It is a rectangle, so both sides are equal. Thus 2x+6=5x-9
SOLVE, SUBTRACT 2x
6=3x-9 THEN ADD 9
15=3x THEN divide by 3
5=x
Plug in x to either side 2(5)+6, to get side length of 16
Then area of a rectangle is lengthxwidth=AREA
substitute what you know 16(y)=48
Divide by 16, thus y=3
