Answer:

174 inches squared

Step-by-step explanation:

Answer:

\frac{4}{n^{2} }

Step-by-step explanation:

(2nm⁻³) * 2m³n⁻³

First, focus on the coefficients, 2*2 = 4.

Now the n, n * n⁻³ = n⁻²

Now the m, m⁻³ * m³ = m⁰ = 1

Now multiply altogether, 4n⁻²(1) = \frac{4}{n^{2} }

Dmitriy789 [7]

Answer: The standard deviation of the sampling distribution is 0.0110

Step-by-step explanation:

The standard deviation of the sampling distribution is given by :-

s=\sqrt{\dfrac{p(1-p)}{n}}

, where p =  population proportion and n = sample size.

Let \hat{p} denote the proportion in the sample who say they support the increase.

As per given :

\hat{p}=24\%=0.24

Then , the standard deviation of the sampling distribution is

s=\sqrt{\dfrac{0.24(1-0.24)}{1500}}=\sqrt{0.0001216}\approx0.0110

Hence, the standard deviation of the sampling distribution is 0.0110.
