According to a recent census, 9% of the people in the United States are of Hispanic
origin. One county supervisor believes her county has a higher proportion of
Hispanic people than the nation as a whole. She looks at their most recent survey
data, which was a random sample of 480 county residents, and found that 48 of those
surveyed are of Hispanic origin. State the null and alternative hypothesis.

i wish i could you, i have no idea how to answer this

step-by-step explanation:

look at photo

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.

hope this : )
