kodGreya [7K]

Answer:

CI=189.5,194.5

Step-by-step explanation:

From the question we are told that:

Sample size n=40

Mean \=x =192

Standard deviation\sigma=8

Significance Level \alpha=0.05

From table

Critical Value of Z=1.96

Generally the equation for momentum is mathematically given by

 CI =\=x \pm z_(a/2) \frac{\sigma}{\sqrt{n}}

 CI =192 \pm 1.96 \frac{8}{\sqrt{40}}

 CI=192 \pm 2.479

 CI=189.5,194.5

What is the sum of 2x^2 and 2x^3
jeyben [28]

For this case we have the following expression:

2x ^ 2 + 2x ^ 3

The terms are not similar, so they cannot be added.

<em>Examples of similar terms:</em>

x ^ 3 + x ^ 3 = 2x ^ 3\\3x ^ 4 + 2x ^ 4 = 5x ^ 4

Then, the expression given can only be rewritten as:

2 (x ^ 2 + x ^ 3)

This is taking common factor 2 to both terms.

Answer:

2 (x ^ 2 + x ^ 3)
