Answer:
1. re-arrange numbers in order.
37, 38, 43, 45, 57, 57, 58
THE MEDIAN IS 45
2. To find Mean, add up all the numbers then divide by how many numbers there are.
when added together, it is 335
335 / 7
47.857
THE MEAN IS 47.857
A scale factor "from A to B" is a number that multiplies some dimension of A to make it equal to the corresponding dimension of B. That is, ...
(scale factor A to B) = (dimension of B)/(corresponding dimension of A)
Your triangles have one corresponding dimension. On triangle A, it is 6 ft. On triangle B, it is 5 ft. Using the above formula, we have
(a) (scale factor A to B) = (5 ft)/(6 ft) = 5/6
The reverse is also true. That is, ...
(b) (scale factor B to A) = (dimension of A)/(corresponding dimension of B)
(scale factor B to A) = (6 ft)/(5 ft) = 6/5
(c) The scale factors are reciprocals of each other.
Answer: the average number of cows per square mile is 37.5, the nearest whole number is 38.
Step-by-step explanation: 48 x 5^6 equals to 750,000 cows spread in (32 x 5^4) 20,000 square miles of land. By dividing 750,000 by 20,000 you get the average number of cows per square mile.
Let x represent the # of units produced and sold.
Then
Revenue = Costs
($40)x = $72000 + ($32)x
Solving for x: $8x = $72000. Thus, x = 9000.
Have to make and sell 9000 units to break even here.
