100-56=44
44/2=22
Answer:
16
Step-by-step explanation:
To solve this question,we will have to understand some symbols in mathematics...
For example,* means ×
/ Means÷
We have so many of them
So back to the question
2*2^3 means 2 multiply by 2 raise to the power of 3
So 2^3 is 8
Therefore,2*8 means 2×8
It equals to 16
Therefore the final answer is 16
I hope you understand it better now

Answer:
Option C is correct.
The test statistic for this question is -3.13
Step-by-step explanation:
To compute the z-test statistic, the formula is given as
z = (x - μ₀)/σₓ
x = p = sample proportion of the 500 college students sampled, that favor reducing the deficit using only spending cuts with no tax increase = (75/500) = 0.15
μ₀ = p₀ = the proportion to be compared against, that is, the proportion of Americans that favor reducing the U.S. budget deficit by using spending cuts only, with no tax increases = 20% = 0.20
σₓ = standard error of the sample proportion = √[p(1-p)/n]
p = 0.15
n = Sample size = 500
σₓ = √[0.15×0.85/500] = 0.01597
z = (0.15 - 0.20) ÷ 0.01597
z = -3.13
Hope this Helps!!!
