Answer:

Squared differences between actual and predicted y

Step-by-step explanation:

The least squares regression method used in predictive modeling for linear regression models produces a best fit line which will minimize the square of the mean difference between the actual and projected or predicted values of the dependent, y variable. Hence, the when the sum of the squared value of the difference between the actual and predicted values (residual) are taken, the fit which gives the minimum sum of squared value is the best fit line upon which the estimated regression equation is based.

Please help with the question 2 to 18

Since these questions all require similar methods of solving, I will only completely work out the first question of each type.

2. To find \frac{7}{10}as a decimal, all we need to do is complete the fraction by dividing the numerator by the denominator.

\frac{7}{10} = 7 / 10 = 0.7

\frac{7}{10} as a decimal is 0.7.

3. To write a fraction as a percentage, we must first convert it into a decimal, the way we did in problem 2.

\frac{13}{20} =0.65

Then to change that number into a percentage, we can either multiply it by 100, or (my personal shortcut) just shift the decimal point over two places to the right.

0.65 = 65%

which is the answer to question 3.
\frac{13}{20} written as a percent is 65%.

4. Writing a percentage as a fraction is a bit easier than writing a fraction as a percentage. All you need to do is place the percentage in the numerator's place of a fraction with 100 as the denominator and simplify.

2%5 = \frac{25}{100}

Since 25 goes into 100 four times, we can simplify this fraction.

\frac{25}{100} = \frac{1}{4}

which is our answer.

25% written as a fraction is \frac{1}{4}.

5. This is the same as problem 3, so I won't show my work for the sake of time.

\frac{2}{5} as a percentage is 40%.

6. This is the same as problem 1, so I will not show steps again.

\frac{3}{20} as a decimal is 0.15.

7. Done similar problems in past. No work shown.

\frac{21}{50} as a percent is 42%.

8. Same as last problem.

\frac{1}{25} as a percent is 4%.

9. Same as number 4.

 6% as a fraction is \frac{3}{50}.

10. Similar in past.

\frac{3}{5} as a percentage is 60%.

11. Same as 6.

\frac{12}{25} as a decimal is 0.48.

12. Done a lot of these so far.

\frac{3}{10} as a percentage is 30%.

13. Just did one like this.

\frac{3}{4} as a percentage is 75%.

14. Same as 4 and 9.

65% as a fraction is \frac{13}{20}.

15. Plenty of these done in past.

\frac{1}{5} as a percentage is 20%.

16. Last problem, and it's just like the one just before this.

\frac{9}{10} written as a percent is 90%.

So there are the results.
Hope that helped! =)

Line p has a slope of 6/7. Line q is perpendicular to p . What is the slope of line q
Serjik [45]

Answer:

The slope of line q is -7/6

Step-by-step explanation:

To find the slope of a perpendicular line, you need to find the opposite reciprocal. So, flip the fraction (7/6) and then take the opposite, (-7/6).

Hope this helps!

Given: AB = 4 AC = 6 What point is in the interior of both circles? H. A. B.
AleksAgata [21]

Answer:

Point A is in the interior of both circles

Step-by-step explanation:

<u><em>Verify each point</em></u>

we know that

Point H is in the interior of greater circle but is outside smaller circle

Point A is the center both circles, then is in the interior of greater circle and is in the interior of smaller circle

Point B is on the smaller circle and is in the interior of greater circle

therefore

Point A is in the interior of both circles
