8.9 At a large university, the graduation rate for
student athletes was reported to be 0.61. For
two of the following, we cannot use this
chapter's methods to find the probability in
question; explain why in each case.
a. The probability that fewer than 3 in a
random sample of 6 athletes at the
university graduate.
b. The probability that fewer than 10 in a
random sample of 29 athletes at the
university graduate.
c. The probability that fewer than 10 in a
random sample of 29 football players at
the university graduate.
a

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
