Estimate 12% of 77.

6

12

8

10

new answer with estimate= 10 old answer=

Step-by-step explanation:

Use this method percent proportion

 or  

12% of 77

Steps:

1. Make a proportion with the method percent proportion.
2. After setting up numbers in proportion cross-multiply.

3. Make 100x because we don't know the value of x.

4. After multiplying 12 x 77 you should've gotten 924.

5. After cross-multiplying divide your new proportion.

6.  estimate = 10

now I'm not sure if those number in your question is your new estimate answer but since 9.24 is close to 10 your answer will be 10

Have a great day hoped it helped :)

Check the explanation

Step-by-step explanation:

So multiple regression model is :

So the calories in a triple whopper with cheese if protein=73 g, total fat=84 g, carbohydrates=52 g, and sodium=5.1 mg per serving is

calories=5.1=1255.98

Residual is :

Third: b

Fourth: a

Fifth: a

Sixth: b

Step-by-step explanation:

Ask me if you need an explanation for any of the questions because there isn't much to explain for rounding.

Fifth: The reason that the answer is not b is because the 6 in that equation should have a - (if it was a typo, the answer should be b)

Step-by-step explanation:

Hello!

Given the variables

Y: Cost of a previously owned Camry.

X: Mileage of a previously owned Camry.

Scatter plot in attachment.

As you can see in the scatter plot, the price of the previously owned Camry decreases as their mileage increases this suggest that there is a negative linear regression between these two variables.

Hypothesis test for the y-intercept

H₀: β₀ = 0

H₁: β₀ ≠ 0

Level of significance α: 0.01

p-value < 0.0001

The decision is to reject the null hypothesis. You can conclude that the population mean of the cost of a previously owned Camry, when the mileage is zero, is different from zero.

H₀: β = 0

H₁: β ≠ 0

Level of significance α: 0.01

p-value: 0.0003

The decision is to reject the null hypothesis. You can conclude that the population mean of the cost of a previously owned Camry is modified when the mileage increases in one unit.

$50.57 ; $175,573.6

Explanation:

The computation of the fixed and variable portions of overhead costs based on machine-hours using high low method is shown below:

Variable cost per hour = (High Overhead cost - low overhead cost) ÷ (High machine hours - low service hours)

= ($581,145 - $503,775) ÷ (8,020 hours - 6,490 hours)

= $77,370 ÷ 1,530 hours

= $50.57

Now the fixed cost equal to

= High overhead cost - (High machine hours × Variable cost per hour)

= $581,145 - (8,020 hours × $50.57)

= $581,145 - $405,571.4

= $175,573.60

$50.57 ; $175,573.6

Explanation:

The computation of the fixed and variable portions of overhead costs based on machine-hours using high low method is shown below:

Variable cost per hour = (High Overhead cost - low overhead cost) ÷ (High machine hours - low service hours)

= ($581,145 - $503,775) ÷ (8,020 hours - 6,490 hours)

= $77,370 ÷ 1,530 hours

= $50.57

Now the fixed cost equal to

= High overhead cost - (High machine hours × Variable cost per hour)

= $581,145 - (8,020 hours × $50.57)

= $581,145 - $405,571.4

= $175,573.60
