195.
set this up as a proportion with 2/3 = 130/x
130 x 3 = 390
390 / 2 = 195
Answer:
I think that it would be 5x+3.
Step-by-step explanation:
Answer:
There was no error
Step-by-step explanation:
There are two types of statistical errors, the type 1 error and the type 2 error. In this case we refute the null hypothesis when the hypothesis is, in fact, false, because the mean process is 9 days instead of 7. Therefore we made no errors.
If the null hypothesis were True, a type 1 error would have ocurred. If the null hypothesis were false and we didnt refute it, then a type 2 error would have ocurred.
133 x 99 = 13167
100% correct
Answers:
<h2>x = 2</h2><h2>z = 117</h2>
Step-by-step explanation:
We can use angle relationships to solve for x and y.
The angles 63° and 6x + 51° are vertical angles. because of this, they must be congruent.
So, 6x + 51 = 63
Subtract 51
6x = 12
Divide by 6
x = 2
Now, we can find z by subtracting 63 from 180, since angles z° and 63° form a line that is 180°. z = 117°.
