Which of the following would NOT be a representative sample from a population of students at a school?a. randomly picking names from the entire school registerb. randomly choosing five names from each year c. randomly choosing 10% of the girls from each class d. randomly choosing the first 50 children to arrive at school in the morning

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

answer:

c 60% on edg

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
