Answer:
49
Step-by-step explanation:
Given:
Width = 0.4
Let's take the z value of 95% which is = 1.96
Let's assume population proportion p1 and p2 = 0.5
For margin of error E, the relation between the width and margin of error is 2E.
i.e 2E = 0.4
E = 0.2
To find the sample size, n, let's use the formula :
= 48.02
≈ 49
Answer:
1/8
Step-by-step explanation:
P(-3, 0) and Y(5,-1)
If PLAY is reflected over x-axis, then P-->P'(-3,0) and Y-->Y'(5,1)
Slope of P'Y' = (1 - 0)/(5+3) = 1/8
