Answer:

Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)

Step-by-step explanation:

First you have to do all the Distributive property which the answer would be:

2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18

Then you have to find the common demoninator which would be 18

After that you have to put them in the correct order since there is two different terms which would be:

2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x

After that you solve the problem which in the end after solving both terms it ends up as..:

10 2/18 - 1 5/18x

and I think that is as simplified as you can go term wise.

I hope this helps and I hope I didn't make a mistake :D

(2 points) The director of an alumni association for a university wants to look at the relationship between the number of years

Gelneren [198K]

Answer:

(A) It is less than the contribution predicted by the regression line.

Step-by-step explanation:

The residual is the subtraction of the observed value by the predicted value.

So, if James has a negative residual, it means that his contribution is less than what was expected by the regression line.

The correct answer is:

(A) It is less than the contribution predicted by the regression line.

Where do (3/2,-7) and (-4,5) intercept

Vinil7 [7]

Answer:

The intercept of the given points is - $\frac{41}{11}$

Step-by-step explanation:

Given points as :

( $x_1$ , $y_1$ ) = ( $\frac{3}{2}$ , - 7 )

( $x_2$ , $y_2$ ) = ( - 4 , 5 )

Now, slope of line using given points can be written as :

Slope = m = $\dfrac{y_2 - y_1}{x_2 - x_1}$

or. m = $\dfrac{5 - ( - 7 )}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\dfrac{12}{( - 4 ) - [tex]\frac{3}{2}$ }[/tex]

or, m = $\frac{12}{\frac{- 8 - 3}{2}}$

Or, m = $\frac{12}{\frac{- 11}{2}}$

∴ m = $\frac{-24}{11}$

So, The slope of the line using points = m = $\frac{-24}{11}$

now, equation of line in slope intercept form can be written as

y - $y_2$ = m × ( x - $x_2$ )

or, y - 5 = $\frac{-24}{11}$ × ( x - ( - 4 ) )

or, y - 5 = $\frac{-24}{11}$ × ( x + 4 )

Or, 11 × ( y - 5 ) = - 24 × ( x + 4 )

Or, 11 y - 55 = - 24 x - 96

Or, 11 y = - 24 x - 96 + 55

Or, 11 y = - 24 x - 41

∴ y = $\frac{-24}{11}$ x - $\frac{41}{11}$

Now, comparing with slope intercept equation

I.e y = m x + c , where c is the intercept

So, The intercept of points is - $\frac{41}{11}$

Hence The intercept of the given points is - $\frac{41}{11}$ Answer

Help Please What’s The Answer!!

JulsSmile [24]

Answer:

c) (6,0)

Step-by-step explanation:

The formula to find a slope is y=mx-b where m is the slope (to find the slope you find the change in y and the change in x) which in this case is -3. The change in y is -3 and the change in x is -1. If you put it on a graph the line is going down from left to right and it intersects the y-axis at 18 meaning if you keep sloping down in a straigt line it intersects the x-axis at (6,0).

Erika calculated that she would spend $115 on school supplies this year. She actually spent $82.50 on school supplies. What is E

DerKrebs [107]

Answer:

Step-by-step explanation:

Percentage error is calculated by

Percentage error = (estimate-real)/real*100%=(115-82.5)/82.5*100%=28.26%

An over-estimate gives a positive error percent, and an underestimate gives a negative error.

Also, dividing by the real value makes it possible to have more than 100% error.

For example, if real cost is $50, and estimated cost is $150, then error percent is (150-50)/50*100%=200%!

C: 39.4%

Step-by-step explanation:

The formula to calculate the percent error is given by :-

Given: The estimated amount = $115

The actual amount = $ 82.50

Now, the percent of error will be given by :-
