The following table contains ACT scores and GPA (grade point average) scores for 8 college students. (The ACT is an SAT-type test, popular at Midwestern schools.
Instead of ranging from 200 – 800, the ACT ranges from 20 – 30.) Grade point average is based on a 4-point scale and has been rounded to one digit after the decimal.
Student GPA ACT
1 2.8 21
2 3.4 24
3 3.0 26
4 3.5 27
5 3.6 29
6 3.0 25
7 2.7 25
8 3.7 30
i) Estimate the relationship between GPA and ACT using OLS; that is, obtain the intercept and the slope estimates for the model
GPAi = α + β(ACTi) + μi
Comment on the direction of the relationship. Does the intercept have a useful interpretation here? Explain. How much higher is the GPA predicted to be if the ACT score increases by 5 points?
ii) Compute the fitted values and the residuals for each observation and verify that the residuals sum to zero.
iii) What is the predicted value of GPA when ACT = 20?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
ACT (X) :
21
24
26
27
29
25
25
30
GPA (Y) :
2.8
3.4
3.0
3.5
3.6
3.0
2.7
3.7
Relationship between GPA and ACT using a linear regression calculator :
ŷ = 0.1022X + 0.56813
Slope = 0.1022
Intercept = 0.56813
The relationship between GPA and ACT is in the positive direction, this can be inferred from the slope value which is positive
The intercept value ; 0.56813 means with a GPA score of 0 ; predicted ACT score will be 0.56813
Explain. How much higher is the GPA predicted to be if the ACT score increases by 5 points?
If ACT score increases by 5 ; predicted GPA will be:
Increase = 0.1022(5)
ACT score will increases by 0.511
ii) Compute the fitted values and the residuals for each observation and verify that the residuals sum to zero.
y = 0.1022(21) + 0.56813 = 2.71433
y = 0.1022(24) + 0.56813 = 3.02093
y = 0.1022(26) + 0.56813 = 3.22533
y = 0.1022(27) + 0.56813 = 3.32753
y = 0.1022(29) + 0.56813 = 3.53193
y = 0.1022(25) + 0.56813 = 3.12313
y = 0.1022(25) + 0.56813 = 3.12313
y = 0.1022(30) + 0.56813 = 3.63413
Residual:
2.8 - 2.71433 = 0.08567
3.4 - 3.02093 = 0.37907
3.0 - 3.22533 = −0.22533
3.5 - 3.32753 = 0.17247
3.6 - 3.53193 = 0.06807
3.0 - 3.12313 = −0.12313
2.7 -3.12313 = −0.42313
3.7 - 3.63413 = 0.06587
0.08567+0.37907−0.22533+0.17247+0.06807−0.12313−0.42313+0.06587 = −0.00044 = 0.00
iii) What is the predicted value of GPA when ACT = 20?
ŷ = 0.1022(20) + 0.56813
= 2.61

carlos is planting a vegetable garden. He has 30 carrot seeds, 24 tomato seeds, and 36 lettuce seeds. Each row will have the same number of seeds, but carrots, tomatoes and lettuce will not appear in the same row. If he puts the greatest possible number of seeds in each row how many rows will there be?
Answer: 15
Step-by-step explanation:
The GCF of 30, 24, and 36 is 6. 30 divided by 6 is 5, 24 divided by 6 is 4, and 36 divided by 6 is 6. 5+4+6=15
The number of rows when he puts the greatest possible number of seeds should be considered as 15.
Calculation of the number of rows:Since
He has 30 carrot seeds, 24 tomato seeds, and 36 lettuce seeds.
So
The GCF of 30, 24, and 36 is 6.
Now we have 30 that should be divided by 6 is 5,
And, 24 divided by 6 is 4,
and 36 divided by 6 is 6
So the no of rows should be
= 5+4+6
=15

Determine if the equation y = 15(1.35)* represents exponential growth or decay and justify. Hint: Think about the growth and decay equations.
Answer:sdfghgfdfghnhgfdfgh
Step-by-step explanatsdfghjhgfghjk
====================================================
Explanation:
The equation is in the form y = a*(b)^x
The 'a' is the initial or starting value. In this case, a = 15.
The b is the base of the exponent which is tied to growth or decay. If 0 < b < 1, then we have decay. If b > 1, then we have growth.
Since b = 1.35, and 1.35 > 1, this means b > 1 and the given equation represents exponential growth.
Solving 1+r = 1.35 leads to r = 0.35. This means the growth rate is 35%

A local ice cream shop sells root beer floats for $2.75 and milkshakes for $6. One day the shop sold 10 more root beer floats than milkshakes and made $290. How many root beer floats were sold on this day? How many milkshakes?
Answer:
30 milkshakes and 40 root beer floats
Step-by-step explanation:
Set up a system of equation (r is root beer and m is milkshake)
2.75r+6m=290
m+10=r
Substitute
2.75(m+10)+6m=290
2.75m+27.5+6m=290
8.75m=262.5
m=30
Now plug in 30 and solve for r
30+10=40

If Kelly walks 2 miles in 80 minutes, then Kelly will walk how far in 110 minutes if she walks at the same
speed the whole time? If necessary, round your answer to the nearest tenth of a mile.
Answer:
2.75 miles
Step-by-step explanation:
Given that,
Kelly walks 2 miles in 80 minutes.
We need to find how far Kelly will walk in 110 minutes if she walks at the same speed the whole time.
Speed = distance/time
So,
[tex]\dfrac{2}{80}=\dfrac{d}{110}\\\\d=\dfrac{2\times 110}{80}\\\\d=2.75\ \text{miles}[/tex]
Hence, she will walk 2.75 miles.
What is the value of k in the following equation?
2(4k + 5) + 3(3 – 3k) = 25
Answer:
K = - 6
Step-by-step explanation:
Let's solve your equation step-by-step.
2(4k+5)+3(3−3k)=25
Step 1: Simplify both sides of the equation.
2(4k+5)+3(3−3k)=25
(2)(4k)+(2)(5)+(3)(3)+(3)(−3k)=25(Distribute)
8k+10+9+−9k=25
(8k+−9k)+(10+9)=25(Combine Like Terms)
−k+19=25
−k+19=25
Step 2: Subtract 19 from both sides.
−k+19−19=25−19
−k=6
Step 3: Divide both sides by -1.

help plz ill give extra points
Answer:
The answer here would be D.
Step-by-step explanation:
When looking at the angle you can see that it is a straight line with a intersecting line. This tells you that you will have supplementary angles, or angles that add up to 180 degrees.
You can only have supplementary angles when they are on either side of a straight line that has been intersected.
Since supplementary angles have to add up to 180 degrees, and you already know that one part of the current supplementary angles is 50 degrees, you can do the math,
180-50=130
To get your answer of D. 130
