Answer:
total area = 193.31 m²
Step-by-step explanation:
rectangle area = 7 x 15 = 105 m²
semi circle area = (3.14)(7.5²)/2 = 88.31 m²
total area = 105 m² + 88.31 m² = 193.31 m²
<span>The variance method is as follows.
-Sum the squares of the values in data set, and then divide by the number of values in data set
- From that, subtract the square of the mean (add all values and divide by number of values in the data set)
Our variance is

Since variance has to be 14, we set

and solve for m

quadratic formula

-4 doesnt' work as it is not a positive integer
m = 11

Answer:
in 220 miles both plans will cost the same
Step-by-step explanation:
38 + .12m = 49 + .07m
38 + .05m = 49
