The second option represents a function. It represents a function because x does not repeat, meaning x is not on the table more than once and does not have a different output.
As with any formula, fill in the values you know and solve for the one you don't know.
A = (b1 +b2)/2*h
24 m^2 = (5 m +7 m)/2 * h
24 m^2 = (6 m) * h
(24 m^2)/(6 m) = h
4 m = h
The height of the trapezoid is 4 meters.
Answer:
8x+10y
Step-by-step explanation:
What you do first is you need to subtract -2y from 9y to get 7y.
So you have (12x+7y)-(4x-3y). The negative sign needs to be added into the problem so it will be (12x+7y)+(-4x+3y). You will then add and minus them together to get 8x+10y.
Answer:
Accept the null hypothesis if it is two tailed test.
Step-by-step explanation:
The null hypotheses can only be accepted if it is a two tailed test and calculated chi square must be less than the critical value of chi square.
Then the difference between the the observed and expected frequencies will be zero.
where
H0 : σ²-σ²= 0 Ha: σ²-σ²≠0
For this the critical region would be greater than the calculated value of chi square. If so we will accept the null hypothesis and reject the alternative hypothesis.
