PART A)
The rate of change is -40 songs each week, because the amount of songs left to be downloaded decrease by 40 every week.
<span>the initial value is 200 at 0
weeks, which means that there are 200 songs to be downloaded at the
beginning</span>
PART B)
<span><span><span>
<span><span>calculate the slope:
</span><span>
m = (y2- y1)/(x2 - x1) = (160 - 200)/(1 - 0)
m = -40
now use the line equation in form of point-slope
y - y1 = m(x - x1)
y - 200 = -40(x - 0)
y = -40x + 200</span></span>

These two events are dependent. When the ball is set aside, there are fewer balls to draw from, so the probability of getting a certain ball becomes greater.
I believe the second one, double check
Answer:
Step-by-step explanation:
80.08 = (8 * 101) + (8 * 1/102)
80.08 = (8 * 10) + (8 * 1/100)
80.08 = 80 + 8/100
80.08 = 80 + 0.08
