Answer:
50
Step-by-step explanation:
your expression: 2j²
plug in j = 5: 2(5)²
solve for the exponent: 2(25)
multiply: 50
Answer:
O 3+(-1)
Step-by-step explanation:
We are given the following data
n = 35
x = 50
s = 2
CI = 95% (z = 1.96)
The formula for the margin of error is
E = z s / √n
Substituting the given values
E = 1.96 (2) / √35)
E = 0.66 or 66%
