Answer:

A linearized model would be the best in this case, since R \simeq 1 .

Step-by-step explanation:

Since, R-value or the correlation coefficient is 0.977 or very close to 1, so

linearized model will be best suitable as least square regression model.

Since,

when R = 1

the points will accurately fall over a straight line having equation of the form

ax + by + c = 0 where a, b, c are fixed but otherwise arbitrary constants.

Please help find the area?!

Hey there! How is your day going?

Sorry if I'm a bit rusty here, math isn't my best subject, necessarily.

If you will notice ABCD is similar in size to EFGH, but the measurements are multiplied by 5. So, all we need to do is multiply the area of ABCD by 5.

35 x 5 = 175

So, your answer is 175 ft²

I hope this helped you, as it has helped me learn a different way to find the area of a rectangle. And I hope you have a very nice day!

Your friend in answering and in need,

~Steve

-x + 5y = 20 12y = 2x + 60

worty [1.4K]

-x+5y=20
5y=x+20
12y=2x+60
6y=x+40
x+20+y=x+40
-x from each side:
20+y=40
-20 from each side:
y=20

-x+5*20=20
-x+100=20
-100 from each side:
-x=-80
x=80

y=20
x=80

Hope this helps :)

2. Jerry has a new job and earns a salary of $45,000. Victoria has a new job and earns a salary of $54,000. Jerry will receive a

Sergio039 [100]

Answer:

Jerry will earn the same as Victoria in 9 years.

Step-by-step explanation:

Giving the following information:

Jerry:

Net income= 45,000 + 2,500x

Victoria:

Net income= 54,000 + 1,500x

x= number of years

Now, we need to equal both formulas and isolate x:

45,000 + 2,500x = 54,000 + 1,500x

1,000x = 9,000

x= 9

Jerry will earn the same as Victoria in 9 years.

Prove:

Jerry= 45,000 + 2,500*9= $67,500

Victoria= 54,000 + 1,500*9= $67,500
