Answer:
Step-by-step explanation:
Speed of the bee = 15 miles per hour.
Formula to represent the speed of the bee will be,
Speed =
Distance = Speed × Time
Therefore, function representing the distance will be,
F(t) = s × t
Where t = time
s = speed
A). F(t) = 15t
B). If t = 20 minutes ≈ hours
F(t) = 15t
F(20) = = 5 miles
C). If f(t) = 12 miles
F(t) = 15t
By substituting these values in the function,
12 = 15t
t = = 0.8 hours ≈ 48 minutes

See explanation and results below.
Step-by-step explanation:
We have the following data:
Age (yr) when award was won Frequency 25-34 31 35-44 36 45-54 12 55-64 4 65-74 6 75-84 1 85-94 2
If we order the data we got the following result. We assume that the midpoint is given by:
The
And the limits are given by the lower and upper limit.
L.Limit U.Limit Class W Midpoint Frequency Limits
25 34 34-25=9 29.5 31 [25-34]
35 44 44-35=9 39.5 36 [35-44]
45 54 54-45=9 49.5 12 [45-54]
55 64 64-55=9 59.5 4 [55-64]
65 74 74-65=9 69.5 6 [65-74]
75 84 84-75=9 79.5 1 [75-84]
85 94 94-85=9 89.5 2 [85-94]
