In the last chapter, we looked at three outliers arising from a plot of Average Wind Speed by Month in the Hopkins Forest. Each

Aloiza [94]

Answer:

Step-by-step explanation:

Hello!

We have the information of the average wind speed for three months:

February:

Mean: 2.324

SD: 1.577

Otlier: 6.73 mph

June:

Mean: 0.857

SD: 0.795

Otlier: 3.93 mph

August

Mean: 0.63

SD: 0.597

Outlier: 2.53mph

Z= X - μ ~N(0;1)

$Z_{February}= \frac{6.73 - 2.324}{1.577}$

$Z_{Februar}= 2.793$ ≅2.79

$Z_{June}= \frac{3.93 - 0.857 }{0.795}$

$Z_{June}= 3.87$

$Z_{August}= \frac{2.53 - 0.63}{0.597}$

$Z_{Augus}= 3.182$ ≅ 3.18

Comparing the three Z-scores you can say that the strongest wind event was in June. The number obtained means that is the furthest one in relation to the mean.

Find the lateral area and the surface area of the right prism.

liraira [26]

Answer:

390 $in^{2}$

Step-by-step explanation:

We know that the top is a rectangle triangle, we only have two of the tree sides and the one that is missing is the hypotenuse. The formula to find it is $h^{2}= a^{2} +b^{2}$

If we put the values we know it would be

$h^{2}= 5^{2} +12^{2}$

$h^{2}= 25 +144$

$h^{2}= 169$

$h=\sqrt{169}$ = 13

So now we have the lenght missing.

The area of the top and bottom is the same and we found it by the formula $\frac{(base)(height)}{2}$ = $\frac{(12)(5)}{2}$ = 30, that is the area of just one triangle, multiply by 2 and that is the area of top and bottom = 30 x 2 = 60
