Answer:

Margin of Error = 10.712

Step-by-step explanation:

The provided information is:

Sample size, n = 27

Mean (\bar{x}) = 250.4

Standard deviation (s) = 32.45

Degree of freedom = n - 1 = 26

Level of significance = \alpha = 0.05

Then, Critical Value is:  t_{\frac{\alpha}{2},df}=t_{0.025,26}=2.06

Thus, Margin of Error:

\begin{aligned}E &= t_{\frac{\alpha}{2},df}\times\frac{s}{\sqrt{n}}\\&=2.06\times \frac{32.45}{\sqrt{27}}\\&=2.06\times5.20\\&=10.712\end{aligned}

Determine whether the given scale factor is a reduction or an
Margaret [11]

Answers:

  • Enlargement
  • The new larger rectangle is 16.8 inches by 8.4 inches

==============================================================

Explanation:

I'm assuming 7/5 is the scale factor. If so, notice how 7/5 = 1.4 which is larger than 1.

The scale factor being larger than 1 means we have an enlargement.

The image is going to be larger compared to the preimage.

The preimage rectangle is 12 in by 6 in. Multiply each dimension by 1.4 to get 12*1.4 = 16.8 and 6*1.4 = 8.4

The image rectangle is 16.8 inches by 8.4 inches
