Katherine's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This
relationship can be represented by the graph below. What does the slope of the line
represent?
A) How many hours a student spends
studying all year.
B) A student's expected quiz score if
they spent 69 hours on their
homework.
195

C) A student's expected quiz score if
they spent no time on their
homework.

D) The change in expected quiz score
for every additional one hour
students spend on their
homework.

Time Spent on Homework per week (hours)

step-by-step explanation:

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
