Answer: 20
Step-by-step explanation:
You find the mean by adding up all the numbers in a data set, then dividing by the number added.
18 + 15 + 22 + 18 + 25 + 19 + 23 + 20 = 160
We added 8 numbers together, so we divide 160 by 8
160/8 = 20
Answer:
5/6−1/9=13/18
Step-by-step explanation:
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(5/6×3/3)−(1/9×2/2)=?
Complete the multiplication and the equation becomes
15/18−2/18=?
The two fractions now have like denominators so you can subtract the numerators.
Then:
15−2/18=13/18
This fraction cannot be reduced.
Therefore:
5/6−1/9=13/18
Answer:
15

Answer:
116*
Step-by-step explanation:
36* + 28* = 64*
180* - 64* = 116*
Answer:
4.33
Step-by-step explanation:
Given data
x1= 3
y1=3
x2=6
y2=16
M= y2-y1/x2-x1
substitute
M=16-3/6-3
M= 13/3
M=4.33
Hence the gradient is 4.33
