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:
Answer:
Hi there
Your answer is
x = -.76 OR -19/25
Step-by-step explanation:
-7x +29 = 6(8+3x)
-7x +29 = 48 + 18x
-18x
-25x +29 = 48
-29
-25x = 19
/-25
x = -.76 OR -19/25
Answer:
different
Step-by-step explanation:
different slopes gives one solution
same slopes with different constant has no solution
same slopes and constants has many solutions
Answer: 2a sqrt 15a
Explanation:
Sqrt 60a^3
= sqrt 4 x 15 x a^2 x a
= 2a sqrt 15a (because 4 and a^2 are a perfect square so we can drag it out of the square root)
