Alexus [3.1K]
Alright, so we have 14 degrees and -10 degrees. The difference between 14 and 0 is 14, and the difference between 0 and -10 is 10. 14+10=24 for total change. For the average over 8 hours, we have 24/8=3 degrees

(Bro I'm so confused) In the diagram, PQRS is a square. Points T, U, V, and W are on sides PQ, QR, RS, and ST, respectively, for
Gnesinka [82]

The total area of square TUVW is 160 meters.

<h3>Find out the sides of PQRS:</h3>

Total area: side x side

256 m = side x side

side =  √ 256

side= 16 m

This means PQ, QR, RS, SP = 16 m

<h3>Find out the area of one triangle:</h3>

Area: 1/2 x base x height

Let's find out the area of the triangle UVR although all triangles are the same.

Base: 4 meters

Height:

RQ= 16

QU= 4

16-4 = 12

Area: 1/2 x 4 x 12 = 24

<h3>Find the total area of the triangles:</h3>

24 x 4 = 96

Finally, find out the total area of the grey square:

Total area of the grey square = Total area of the white square - area of the triangles

Total area = 256 - 96

Total area= 160

In a random sample of fivefive microwave​ ovens, the mean repair cost was ​$75.0075.00 and the standard deviation was ​$13.0013.
Radda [10]
<h2>Answer with explanation:</h2>

As per given , we have

Sample size : n= 5

Degree pf freedom = : df= 5-1=4

\mu=\$75.00

\sigma=\$13.00

Significance level for 90% confidence = \alpha=1-0.90=0.1

Using t-value table , t-critical value for 90% confidence:

t_{\alpha/2, df}=t_{0.05, 4}=2.132.

Margin of error of \mu: E=t_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\(2.132)\dfrac{13}{\sqrt{5}}=12.3949720129\approx12.39

Interpretation : The repair cost will be within $12.39 of the real population mean value \mu 90% of the time.
