Answer:
What?
Step-by-step explanation:
That is called a angle to angle math . the square lenth its ask like A to B is 20 cm long away so. that is a good question.
The roof is made up of two mirred right triangles which are congruent. We can find the width by finding the width of one of the triangles then doubling the answer to get the width of the entire roof.
We are given that the slope (rise over run) is 5/12 which means that for every 5 feet of height there is 12 feet of width. We can use this ratio to find the width of one triangle given the height of 8 by setting up the following proportion:
5/12 = 8/x
Solve for x by cross multiplying:
5x = (12)(8)
x = (12)(8)/5
x = 19.2 feet
Multiply by 2 to get the entire width:
(19.2)(2) = 38.4 feet
The answer is 38.4 feet
Answer:
A matched-pairs hypothesis test for μD
Step-by-step explanation:
The trainer wants to compare each athlete's time before the program to the time after the program. Since we're comparing times for the same athlete, the data is paired, so we should use a matched-pairs test.
