Answer:
No
Step-by-step explanation:
We have:
n = 80,
p = 0.1 (10%)
q = 1 - p = 1 - 0.1 = 0.9
Usually we use
np > 5, and nq > 5, but this question is using
np > 10, so we'll use that. It means that the proportion times the sample size must be greater than 10, we have
80(0.1) = 8 and
80(0.9) = 72,
since we got 8 as one answer, the situation doesn't hold up.
For this we are going to use the equation f(x)=a|x+h|+k
Since there is no a shown, we know that a=1. This means the slope of the graph by 1's. (slope=1 one on the right side and slope=-1 on the left, because absolute value graphs are shaped like a "v".)
Since h=-2, just move the function to the left 2 units.
Since k=5, move the function up 5 units.
This basically means the vertex of the function is at the point (-2,5).
So put the point (-2,5) on your graph, then make the v-shape with a slope of 1 on the right side, and -1 on the left.
Sometimes if you aren't sure how the graph will look, just plug x-values into the function to get their corresponding y-values. Then see how the graph looks to check.
