There need to be 10 volunteers at the start of the race. In previous years, 30% of volunteers showed up late and 10% did not show up at all. The director
assigns 15 volunteers to the race start.
Part A
What is the probability that 10 of the volunteers show up on time? What is the
probability that more than 10 of the volunteers show up on time? Explain.
I
Part B
What is the probability that 10 of the volunteers show up? What is the
probability that more than 10 of the volunteers show up? Explain.
Part
Is the director assigning enough volunteers to the race start? Is the director
assigning too many volunteers? Explain.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
