Researchers are studying the effects of exercise on resting pulse rates. They have found 20 men to participate in the study. 10 of the men get at least 150 minutes of moderate exercise each week (Group 2) and the other 10 men do not exercise (Group 1). The resting
pulse rate data for the two groups at the end of the study are shown in the table. The pulse rates are in beats per minute

c.

step-by-step explanation:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
