Step-by-step explanation:
You have fit a regression model with two regressors to a data set that has 20 observations. The total sum of squares is 1000 and the model sum of squares is 750.(a) What is the value of R2 for this model?(b) What is the adjusted R2 for this model?(c) What is the value of the F-statistic for testing the significance of regression? What conclusions would you draw about this model if α = 0.05? What if α = 0.01?(d) Suppose that you add a third regressor to the model and as a result, the model sum of squares is now 785. Does it seem to you that adding this factor has improved the model?
Answer:
0.75
0.7205882
25.5
Result is significant at α = 0.01 and α = 0.05
Model improved
Step-by-step explanation:
Given that:
Number of observations (n) = 20
Total sum of squares (SST) = 1000
Model sum of squares (SSR) = 750
1) R² = SSR / SST = 750 / 1000 = 0.75
2.)
Adjusted R² = [(SST - SSR) /(n-k-1)] / (SST ÷ (n - 1))
k = number of regressors = 2
Adj R² = 1 - ((1000 - 750) / (20-2-1)) / (1000 / (20 - 1))
1 - 0.2794117 = 0.7205882
3.) Fstat = (SSR / k) / ((SST - SSR) / (n - k-1))
= (750 /2) / ((1000 - 750) / (20 - 2 - 1))
= 25.5
4.) At α = 0.05
Fα,k,(n - k-1) = F0.05, 2, (20 - 2 - 1) = F0.05,2, 17 = 3.5915 (f distribution calculator)
Fstat > F0.05, 2, (20 - 2 - 1)
25.5 > 3.5915 (Hence result is significant at α = 0.05
At α = 0.01
Fα,k,(n - k-1) = F0.01, 2, (20 - 2 - 1) = F0.01,2, 17 = 6.112 (f distribution calculator)
Fstat > F0.01, 2, (20 - 2 - 1)
25.5 > 6.112 (Hence result is significant at α = 0.01
Adjusted R² if a 3rd regressors is added : k = 3
Adjusted R² = [(SST - SSR) /(n-k-1)] / (SST ÷ (n - 1))
k = number of regressors = 3
SSR = 785
Adj R² = 1 - ((1000 - 785) / (20-3-1)) / (1000 / (20 - 1))
1 - 0.2553125 = 0.7446875
Adjusted R² value is now 0.7446875 which is greater than with 2 regressors,. Hence, adding a third regressors improved the model.

Gabriela is weighing quarters on a scale. She weighs various numbers of quarters, n, and
records their total weight, w, in grams. Find the ratio of the weight of the quarters to the
number of quarters for all three columns of the table. Express your answer using decimals.
Number of quarters, n 4,10,24
Tirol weight, w 22,55,132
The ratio of the weight of the quarters to the number of quarters will be 11: 2
What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.
We have been given that Gabriela is weighing quarters on a scale. They weigh various numbers of quarters, n, and record their total weight, w, in grams.
Number of quarters, n; 4,10,24
Tirol weight, w; 22,55,132
The ratio of the weight of the quarters to the number of quarters will be;
w: n
22 : 4 = 11 : 2
Also, 55: 10
11: 2
Again,
132: 4
11: 2
Hence, The ratio of the weight of the quarters to the number of quarters will be 11: 2

Answer:
g^2 + 4 > -5
Step-by-step explanation:
sum implies addition so add it with 4
i can’t put the equal to thing on here but there is supposed to be a line under the greater than symbol
Answer:
[tex]g\geq +/- 3i[/tex]
Step-by-step explanation:
Using clues given in the problem, we can set up a solvable inequality.
A number g squared: [tex]g^{2}[/tex]
The sum of a number g squared and 4: [tex]g^{2}+4[/tex]
Is greater than or equal to: [tex]g^{2}+4\geq[/tex]
Greater than or equal to -5: [tex]g^{2}+4\geq-5[/tex]
Isolate [tex]g[/tex]:
[tex]g^{2}\geq -9[/tex]
Solve for [tex]g[/tex]:
[tex]\sqrt{g^{2}}\geq \sqrt{-9}[/tex]
This^ looks bad because of the negative, but as I'll show you in the next step it can be split up and you will use the value [tex]i[/tex], or [tex]\sqrt{-1}[/tex].
[tex]g\geq \sqrt{9} \sqrt{-1}[/tex]
[tex]g\geq +/-3i[/tex]
I hope this helps!

9. 123
Step-by-step explanation:
5. Corresponding angles are angles that in the same position. Examples of corresponding angles in this diagram would be, <1 and 5, <2 and <6, etc
6. Supplementary angles add up to 180 degrees. Angles < and <3 (answer choice B) are vertical angles (angles who equal each other) so they are not supplementary angles
7. m<7 and m<2 are alternate exterior angles which means that they equal each other. Another example of this angle pair is m<1 and m<8
8. m<5 and m<3 are same side interior angles, which means that they add up to 180 degrees. Another example of this angle pair is <4 and <6
9. m<1 and m<6 add up to 180 degrees.
The graph shown below represents the relationship between the number of cookies and the cost of the cookies that a bakery sells. What is the unit rate and what does it represent? Y 13 12 10 9 ME Cost ($) B 12 14.06L 8 10 12 14 16 18 20 22 24
Answer:
[tex]Rate = \$0.5[/tex] per cookie
Every cookie is sold at $0.5
Step-by-step explanation:
See attachment for complete question
Required
Determine the unit rate
To solve this, we simply take any corresponding values of Cost of cookies and number of cookies
When
Cost = $2
Number = 4
[tex]Rate = Cost/Number[/tex]
[tex]Rate = \$2/4[/tex]
[tex]Rate = \$0.5[/tex] per cookie
Pick another corresponding values
When
Cost = $6
Number = 12
[tex]Rate = Cost/Number[/tex]
[tex]Rate = \$6/12[/tex]
[tex]Rate = \$0.5[/tex] per cookie
Hence, the unit rate is $0.5 per cookie
What it represents is that: Every cookie is sold at $0.5

Find the distance between (6,4) and (-6,-5) by using the distance formula
Answer:
[tex]\boxed {d = 15}[/tex]
Step-by-step explanation:
Use the Distance Formula to help determine the distance between two given points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Substitute both given points:
[tex](x_{1}, y_{1}) = (6, 4)[/tex]
[tex](x_{2}, y_{2}) = (-6, -5)[/tex]
[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]
-Solve for the distance:
[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]
[tex]d = \sqrt{(-12)^{2} + (-9)^{2}}[/tex]
[tex]d = \sqrt{144 + 81}[/tex]
[tex]d = \sqrt{225}[/tex]
[tex]\boxed {d = 15}[/tex]
Therefore, the distance is [tex]15[/tex].
82 divided by 10 1/2
Answer:
164/21
Step-by-step explanation:
82÷10 1/2
82÷21/2
82×2/21
164/21
So the Answer is 164/21
The value of the division of the 82 by 10¹/₂ is 164/21.
The mixed number (10 1/2) can be changed into an improper fraction in order to divide 82 by it. In order to do this, we multiply the whole number (10), by the fraction's denominator (2), and then add the numerator (1).
This gives us 10 x 2 + 1 = 21.
So, 10 1/2 can be written as the improper fraction 21/2.
To divide 82 by 21/2, we can multiply 82 by the reciprocal of 21/2. The reciprocal of a fraction is found by flipping the numerator and the denominator.
Therefore, the reciprocal of 21/2 is 2/21.
Multiply 82 by 2/21:
82 x (2/21) = 164/21.
So, 82 divided by 10 1/2 is equal to 164/21.

(b) Suppose you have 6 pairs of socks in your sock drawer. It is still dark out in the morning when you get dressed for your 8am CSE 21 class, so you just pull socks out of the drawer at random, one at a time, until you have removed two matching socks. What is the probability that you pull out exactly 5 socks from your sock drawer in the morning?
Answer:
a)
hearing one song = 2%
90/2 = 45
hearing song 45 times = 90%
Answer:

A hobby store pays $20 wholesale for drones and marks them up 40%. What is the retail price of each drone?
Answer:
$28.00
Step-by-step explanation:
20 x 1.4
Answer:
$28
Step-by-step explanation:
To find the retail price you have to find 40% of 20 and then add that value to 20.
To find 40% of 20 let's convert 40% into decimal form: 0.4
Then you multiply: 20 * 0.4 = 8
Now you add 8 to the original 20: 20 + 8 = 28
The retail price of each drone is $28.

(8x - 20)°
(3x + 5)°
Answer:
Step-by-step explanation:
Simplifying :8x + -20 = 3x + 5
Reorder the terms:-20 + 8x = 3x + 5
Solving:-20 + 8x = 5 + 3x
Add '-3x' to each side of the equation:-20 + 8x + -3x = 5 + 3x + -3x
Combine like terms: 8x + -3x = 5x :-20 + 5x = 5 + 3x + -3x
Add '20' to each side of the equation:-20 + 20 + 5x = 5 + 20
Combine like terms: -20 + 20 = 0 :0 + 5x = 5 + 20
5x = 5 + 20
Divide each side by '5':x = 5
Simplify:x=5
