To find the mean of a data set, you need to take all the data in the set and add them together.

Example: Sarah scored these numbers on her midterms every quarter: 89, 97, 76, & 62. What is the mean of her test scores?

So, add all the scores together.

89 + 97 + 76 + 62 = 324

After adding the scores together, you need to divide the sum by the number of numbers in the data set.

324 ÷ 4 = 81

So, the mean, or average of her test scores is 81. 

I hope I helped :)

The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK:KL:LMJK:KL:LM is equal to 1:
RideAnS [48]

Answer: JL = 25

Step-by-step explanation: Segment JM is the total measure of the line segment and it equals 45.

Suppose first segment JK measures d.

The total ratio is the sum of each part

d + 4d + 4d = 9d

The sum of each part corresponds to the total measure of the line segment. Then:

9d = 45

d = 5

Segment JL is

JL = d + 4d

JL = 5d

JL = 5.5

JL = 25

Segment JL measures 25 units.

Verdich [7]

Answer:

b = $4000

Step-by-step explanation:

Let b represent the bonus amount.

Then the bonus, b, less the three deductions, is represented by

b - 0.30b - 0.30b - 025b, and this comes to $600.  Find the value of b.

b - 0.85b = $600, or

0.15b = $600

Then b = $4000
