If ABCD is a rectangle, find the length of each diagonal. AC=3c/9 and BD=4-c

1 answer:

4 0

So we know that the diagonals of a rectangle are equal than

3c/9 = 4 - c

c/3 = 4-c

c = 3(4-c)

c = 12 -3c

4c = 12

c = 12/4

c = 3

so in this case the length of AC = 3*3/9 = 9/9 = 1 and the length of
BD = 4 - 3 = 1

hope this will help you

kap26 [50]

Answer : There are no more than 10% of homes in the city are not up to the current electric codes but actually we do not have evidence to accept it.

Explanation:

The Type I error occurs when the null hypothesis is true but we reject it.

Given null hypothesis : $H_0$ : an electrician claims that no more than 10% of homes in the city are not up to the current electric codes.

The Type I error for the given situation is that there are no more than 10% of homes in the city are not up to the current electric codes but actually we do not have evidence to accept it.
