A shipment contains 7 igneous, 5 sedimentary, and 5 metamorphic rocks. If 9 rocks are selected at random, find the probability that exactly 5 are sedimentary.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

a: inscribed angles

step-by-step explanation:

i reviewed this question with a peer and teacher, seems to be correct, me later
