The standard deviation of pulse rates of adult males is more than 11 bpm. For a random sample of 152 adult​ males, the pulse rates have a standard deviation of 11.2 bpm. Required:
a. Express the original claim in symbolic form.
b. Identify the null and alternative hypotheses.

f(x) = y

f(-3) = -5

step-by-step explanation:

6mm^3 or .6cm^3

      216

      /   \

  36     6

  /   \     /

6     6   6

factor trees are nice.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
