Answer: 10%

Step-by-step explanation:

The difference between his estimated and actual distance is 15 - 13.5 = 1.5

The percentage of error is the difference divided by the actual value.

1.5÷15 = 0.10

Converted to a percentage, it is 10%

Anastasy [175]

Answer:

I think it is 2/9 or 0.22

Step-by-step explanation:

You know they have the same y intercept, so first you should find the y intercept of the givern equation.

x+2y = 10

2y = -x + 10 [subtract x]

y = -.5x + 5 [divide by 2]

Now you have the equation in graph form, and know the y intercept is 5.

If the unknown function has the same y intercept, you know it contains the point (0,5), and it is given that it includes the point (9,7)

now that you have two points, you can use slope formula.

(y2 - y1)/(x2-x1)

(change in y)/(change in x)

so,

(7-5)/(9-0) = 2/9 = 0.2

someone please correct me if i'm wrong:)

29.99 * 3 =89.97 89.97 with 30% off = 62.98 and 5% of 62.98 =3.15 so 62.98 + 3.15 = 66.13$

180.00 + 14.95 + 8.95 = 203.09 - 15% = 173.44 + 4% = 180.38

5.65 + 5% of 5.65 = 5.93

i think this is all right you might want to check my work!

Dahasolnce [82]

Answer:

Newspaper

Step-by-step explanation:

The level or degree of significance of independent variables used in a multiple regression analysis is usually measured by comparing the values of the slope Coefficient of each independent variable. From the result of the multiple regression analysis attached. The slope Coefficient of each independent variable is :

Television = 2.38 ; Newspaper = 1.45 and Mail = 1.82.

This slope values are the rate at which the dependent variable changes per unit increase in each of the independent variable.

Newapaper has the least slope Coefficient value of the 3 independent variables and hence will have the least significant effect on the value of revenue.
