Answer:
Step-by-step explanation:
You add 42 and 16 and then u have 58 dollars/$58
p = 0.25
q = 1 - p = 0.75
x = 82
n = 400
psample = x/n = 82/400 = 0.205
test statistic, z = (psample - p) / sqrt(pq/n) = (0.205 - 0.25) / sqrt(0.25×0.75/400) = -2.078
71-46=25
25*8=200
she now has 200 pieces of paper<span />
