The first is an absolute value sign. But there is a - outside the first one so the -4 does become positive but then becomes negative again so you have -4
The second value is basically saying the same thing as -1x-4 which become a negative times a negative which is positive. You end up with 4.
So no it does not equal each other.
I do see an extra absolute value symbol though on the right side of the equal sign. But it looks like either way it would be -4 = 4 and that's not true. So either way it should be false.
Answer:
<h3>83°</h3>
Step-by-step explanation:
Given the parameters
m2 ROC = 31° and
m2 COL = 52°
According to the diagram in the attachment;
m2 ROL = m2 ROC + m2 COL
Substitute the given values into the expression as shown;
m2 ROL= 31°+52°
m2 ROL = 83°
Answer:
21.16
Step-by-step explanation:
Starting from the theory we have the following equation:

Using the data supplied in the exercise, we have subtracting the mean and dividing by the standard deviation:

solving for "c", knowing that fi is a tabulating value:

therefore the value of c is equal to 21.16
X= 2.5 that is the correct answer
