The accompanying data represent the pulse rates (beats per minute) of nine students. Treat the 9 students as a population. Compute the z-scores for all the students. Compute the mean and standard deviation of these z-scores. Student Pulse z-score1 762 613 604 805 726 807 808 689 73Complete the table z-score (round to the nearest hundredth as needed)The mean of z-score is The standard deviation of the z-scores is?

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
