Mr. Mauk surveyed 50 high school students in his driver-education course to determine how many times most motorists have taken a driver-education course. Which of the following best explains why the results of Mr. Mauk's survey may NOT be valid? F He did not include motorists from other driver-education courses.
G He should have included adults who have taken driver-education courses.
H He should have included taxi drivers in his survey.
J The sample used in his survey may not have been representative of most motorists.​

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

jfkc

step-by-step explanation:

jhcxzbfzc

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
