Solution:
p = 0.25
q = 1 - p = 0.75
x = 127
n = 480
psample = x/n = 127/480 = 0.2645
test statistic, z = (psample - p) / sqrt(pq/n) = (0.2645 - 0.25) / sqrt(0.25×0.75/480) = 0.733
B) translation (up 3, right 5)
c) rotation 90° clockwise
d) reflection over y=x
Answer:
Our answer is
.
Step-by-step explanation:
To solve for x, we need to isolate the variable. We can do so by subtracting 2 to both sides.

Our answer is
.
To find the decimal, calculate with a calculator.
