Answer:

G: The residual plot given displays the linear model from the regression calculator as being a good model for it represets the points and how the linear model compared to the residual model calculates to a similar, if not same result.

Based on the equation we did for 2d:

\frac{predicted value}{measured value} = residual

9.2-2.23=6.97\\19.5-3.77=15.73\\15.5-3.92=11.58\\0.7-1.11=-1.04\\21.9-3.60=18.3\\13.8-1.42=12.38

H: We can interpret the average or close accurate of a student that studies for 15 hours a week to be around 3.92 based on previous findings. Along with that, the scatterplot should be different by the first set of differences that was subtracted.

When plotting the new points, be sure to make them a seperate color of shape (depending on how creative you wish to be) so you can tell the two apart form one another.

Hope this Helps!

Answer:

G) Yes, because the plots and the linear model both align to produce a similar calculated sum.

H) I need to see the data table again for step 2d.

Step-by-step explanation:

1.) You scatter plot should be off by 6.97, since that was the first difference in your data table set of terms.

Basically subtract all of the GPAs from the Hours in the table.

Ex). Hours - GPA = Difference

or like before,

      9.2 - 2.23 = 6.97

Do the rest of the numbers like this then plot the answers.  I'd advise you plot your second set of scatter plot points in a different color.

The value of the solid's surface area is equal to the value of the solid's volume. Find the value of x. We know the length is 9
Lerok [7]

Given:

The value of the solid's surface area is equal to the value of the solid's volume.

Length(l) = 9 units

width(b) = 4 units

Height(h) = x units

To find:

The value of x.

Solution:

Solid's surface area is

Area=2(lb+bh+hl)

Area=2(9\times 4+4\times x+x\times 9)

Area=2(36+4x+9x)

Area=2(36+13x)

Area=72+26x

Volume of solid is

Volume=l\times b\times h

Volume=9\times 4\times x

Volume=36x

Solid's surface area = Volume of solid

72+26x=36x

72=36x-26x

72=10x

Divide both sides by 10.

7.2=x

Therefore, the value of x is 7.2.

5 roommates share the cost of an apartment: rent,electricity, and gas. rent costs 1800 and gas costs 150 per month. each roommat
Naddik [55]

Answer:

Electricity bill is 175

<em />

Step-by-step explanation:

Given

Rent = 1800

Gas = 150

Each\ Roommate = 425 monthly

Number\ of\ Roommate = 5

Required

Determine the electricity bill

If each roommate pays 425, then 5 roommates pay 5 * 425

Total = 5 * 425

Total = 2125

This implies that: the monthly cost of room, gas and electricity add up to 2125.

In other words,

Gas + Rent + Electricity = 2125

150 + 1800+ Electricity = 2125

1950+ Electricity = 2125

Electricity = 2125 - 1950

Electricity = 175

<em>Hence, the electricity bill is 175</em>

adult tickets at a football game cost $6 and student tickets cost $2. A total of $1776 was collected on 372 tickets. How many ad
postnew [5]

Answer:

258

Step-by-step explanation:

Set up the two equations needed (x is the adult tickets and y is the student tickets)

x+y=372

6x+2y=1776

Solve by elimination

-2(x+y=372)

=-2x-2y=-744

Cancel like figures:

-2x-2y=-744

6x+2y=1776

= 4x=1032

x=258
