I think around 44% chance that all three flights would arrive on time, but i'm not that sure.

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

You and your friend are practicing for a rowing competition and want to know how far it is to an island in the Indian River Lago

zepelin [54]

The drawing is missing, so i have attached it.

Answer:

24 yards

Step-by-step explanation:

From the image, we can see that AB and DE are both adjacent sides of their respective triangles.

While, CE and BC are both opposite sides of their respective triangles

Now, from your side, x is the distance to the island.

So, from ratio of similar triangles, we can find x.

Thus;

8/x = 3/9

Cross multiply to get;

8 × 9 = 3x

3x = 72

x = 72/3

x = 24

Thus, distance from your side to the island is 24 yards

If you pick a gumball at random, put it back, and then pick another gumball at random, what is the probability of picking a blue

Fynjy0 [20]

Hi there!

It depends on how many colors of gumballs there are and how many gumballs there are in total. With those, we can set the fraction to each gumball color.

Hope this helps!

Of the 21 children at a park, 5 of them are playing on the swings. What is the approximate

Bond [772]

The Answer Is B

Use proportions to find x% of the children playing on the swings.

$\frac{21}{100} = \frac{5}{x\%}$

$x = 23.80952380\%$

Meaning B is correct.
