The answer is B.
Because half of 35 and 30 is 32.5 so She can expect to grow 2.5 each year.
I hope this helps :)
6*30 = 180
8*20 = 160
9*10 = 90
180+160+90 = 430 stickers
Answer:
C - graph D
Step-by-step explanation:
when plotting this line we can look at the slope and the y intercept
2 is the slope so it goes up 2 over 1
and the y intercept is 3 so the line meets the y axis at (0, 3)
the graph that shows this is D
Part a is correct.
Part b can be done a couple ways.
1) Use binomial distribution. p = 0.2, n = 144
P(x>3) = 1 - P(x=0) -p(x=1) -p(x=2) -p(x=3)
where
![P(x=k) = (nCk)p^k (1-p)^{n-k}](https://tex.z-dn.net/?f=P%28x%3Dk%29%20%3D%20%28nCk%29p%5Ek%20%281-p%29%5E%7Bn-k%7D)
2) Assume a normal distribution with mean = 28.2, stdev = 4.8
![z = \frac{4 - 28.2}{4.8} = -5.04](https://tex.z-dn.net/?f=z%20%3D%20%5Cfrac%7B4%20-%2028.2%7D%7B4.8%7D%20%3D%20-5.04)
Look up z-value in normal table to find probability.
Hope that helps.
