Answer:
Step-by-step explanation:
how the prices at Payless compared to the prices
at Famous Footwear. At each store, they randomly
selected 30 pairs of shoes and recorded the price of
each pair. The table shows summary statistics for
the two samples of shoes.28
Store

Do these data provide convincing evidence at the
0.05 significance level that shoes cost less
, on
average, at Payless than at Famous Footwear?

The legs are 5 inches long.
Use the Pythagorean theorem:
![5^2+5^2=c^2 \\ 25+25=c^2 \\ 50=c^2 \\ c=\sqrt{50} \\ c=\sqrt{25 \times 2} \\ c=5 \sqrt{2} \\ c \approx 7](https://tex.z-dn.net/?f=5%5E2%2B5%5E2%3Dc%5E2%20%5C%5C%0A25%2B25%3Dc%5E2%20%5C%5C%0A50%3Dc%5E2%20%5C%5C%0Ac%3D%5Csqrt%7B50%7D%20%5C%5C%0Ac%3D%5Csqrt%7B25%20%5Ctimes%202%7D%20%5C%5C%0Ac%3D5%20%5Csqrt%7B2%7D%20%5C%5C%0Ac%20%5Capprox%207)
The length of the hypotenuse of the triangle is approximately 7 inches long.
You start at 0 on the unit circle the cos of 0 =1, but at cos 0 there is no angle at all so there is no y value so at cos 0 y=0, 180 is the opposite direction of the starting point which is 0 so the x value of cos180= -1 but there is still no upward or downward angle ie.. y value. so the y value = 0 at 0 and 180. answer is 0
Answer:
Dilate circle A by a scale factor of 3.
Step-by-step explanation:
Generally, similar figures have sides in the same ratio
3(5) = 15
When dilate A by factor 3, it will look exactly like B
