Estimate 12% of 77. 6 12 8 10

Step-by-step answer

P Answered by Specialist

new answer with estimate= 10 old answer= 9.24

Step-by-step explanation:

Use this method percent proportion

$\frac{Percent}{100} = \frac{Part}{Whole}$ or $\frac{Percent}{100} = \frac{is}{of}$

12% of 77

$\frac{12}{100} = \frac{x}{77} = \frac{100x}{100} = \frac{924}{100} x = 9.24$

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. x= 9.24 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 :)

Like many fast-food restaurant chains, Burger King provides information on the nutrition content of its menu items. This Excel file Burger King shows information for most Burger King menu items. The variables are Calories, Protein content (g), Total Fat (g), Carbohydrate (g), and Sodium (mg) per serving. A triple whopper with cheese is not included in the Excel data file. Estimate 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. (use 2 decimal places in your estimate).

Step-by-step explanation:

So multiple regression model is :

calories= 6.53+3.84Protein+9.14Fat+3.94carbs-0.69sodium

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= $6.53+3.84\cdot 73+9.14\cdot 84+3.94\cdot 52-0.69\cdot$ 5.1=1255.98

Residual is :

$actual\, value\,of \,number\,of\,calories-estimated\,value\,of\,number\,of\,calories$

$1250-1255.98\\=\textbf{-5.98}$

The Toyota Camry is one of the best-selling cars in North America. The cost of a previously owned Camry depends on many factors, including the model year, mileage, and condition. To investigate the relationship between the carâ€™s mileage and the sales price for Camrys, the following data show the mileage and sale price for 19 sales (PriceHub web site, February 24, 2012).Miles(1000s) Price($1,000s) 22 16.2 29 16.0 36 13.8 47 11.5 63 12.5 77 12.9 73 11.2 87 13.0 92 11.8 101 10.8 110 8.3 28 12.5 59 11.1 68 15.0 68 12.2 91 13.0 42 15.6 65 12.7 110

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
