Answer:

he positive regions of a function are those intervals where the function is above the x-axis. It is where the y-values are positive (not zero). The negative regions of a function are those intervals where the function is below the x-axis. It is where the y-values are negative

He total variance is $35000 f. the total materials variance is $14000 f. the total labor variance is twice the total overhead va

TiliK225 [7]

Assume that the total overhead variance is x
We are given that the total labor variance is twice the total overhead variance. This means that, the total labor variance is 2x

Total variance can be calculated as follows:
Total variance = Total materials variance + Total overhead variance
+ Total labor variance

We have:
Total variance = $35000
Total materials variance = $14000
Total overhead variance = x
Total labor variance = 2x

Substitute in the equation and solve for x as follows:
35000 = 14000 + x + 2x
35000 - 14000 = 3x
21000 = 3x
x = 21000/3
x = 7000

Based on the above calculations:
Total overhead variance = x = $7000
Total labor variance = 2x = 2*7000 = $14000

Craig made 60% of 80 free throw attempts this season how many free throws has he made

Svetllana [295]

Answer:

Step-by-step explanation:

60% of 80 is the same as 60% times 80.

60% of 80 =

= 60% * 80

= 0.60 * 80

= 48
