From the three residual plots provided, data set A is the best fit by the Regression line. It can be observed that the residuals in data set A are randomly scattered around the zero line, and there is no visible pattern in the plot. In contrast, data set B and C's residual plots exhibit a curved pattern,
The residual plot is used to assess the validity of the assumptions about the residuals in regression analysis. Residuals are computed as the difference between the predicted and observed values of the response variable.
The residual plot displays the residuals against the explanatory variable or predictors (time, in this case), providing a visual examination of the relationship between the residuals and the response variable. From the residual plot, the validity of the following assumptions can be assessed:
The residuals should be randomly distributed and the residuals should be normally distributed, and they should have constant variance across the range of the response variable. The residuals should not have any patterns.
From the three residual plots provided, data set A is the best fit by the regression line. It can be observed that the residuals in data set A are randomly scattered around the zero line, and there is no visible pattern in the plot. In contrast, data set B and C's residual plots exhibit a curved pattern,
which is indicative of nonlinearity or a lack of fit of the regression model. Additionally, data set C's residual plot shows a pattern in the form of increasing variance as the time goes on, which indicates heteroscedasticity or non-constant variance.
The normality assumption is met in all three sets, as the residual plot follows a rough normal pattern and has a similar spread on both sides of the zero line. Hence, data set A is the best fit by the regression line because its residual plot shows no pattern or trends, and residuals are randomly distributed around zero with constant variance.

The University of Texas at Austin has three times as many students enrolled as the University of Miami. The University of California, Berkley has 3,000 more than twice the number of students as the University of Miami. If the three schools have a total enrollment of 96,000 students, what is the enrollment at each school?
Step-by-step explanation:
let the University of Miami enrolment be x
so the University of Texas at Austin has three times = 3x
The University of California, Berkley has 3,000 more than twice the number of students at the University of Miami.
this can be translated as = 3000+2x
in total, the enrolment is 96,000
therefore
x+3x+3000+2x=96000
we can now solve for x
6x=96000-3000
6x=93000
divide both sides by 6 we have
x=15500
1. The University of Miami enrolment is 15500 students
2. The University of Texas at Austin has three times = 3x
=3*15500
= 46500 students
3. The University of California, Berkley has
= 3000+2x
= 3000+2(15500)
=3000+46500
=49500 students

The stock of Company A lost $0.68 throughout the day and ended at a value of $67.32. By what percentage did the stock decline?
Given parameters:
Amount lost on stock = $0.68
Closing value = $67.32
Unknown:
Percentage of stock decline = ?
To solve this problem, simply express the amount of decline over the closing value and multiply by 100;
Percentage of stock decline = [tex]\frac{amount of stock lost}{closing value}[/tex] x 100
Simply input the parameters and solve;
Percentage of stock decline = [tex]\frac{0.68}{67.32} x 100[/tex] = 1%
The stock declined by a percentage of 1%
f(x) = 3x^2 + 4x - 6
g(x) = 6x^3 – 5x^2 - 2
Find (f - g)(x).
Answer:
(f-g)(x) = -6x^3 + 8x^2 + 4x - 4
Step-by-step explanation:
subtract g(x) from f(x)
(f-g)(x) = (3x^2 + 4x - 6) - (6x^3 - 5x^2 -2)
distribute the negative
(f-g)(x) = 3x^2 + 4x - 6 - 6x^3 + 5x^2 +2
like terms and in order of exponent
(f-g)(x) = -6x^3 + 8x^2 + 4x - 4

Answer:
There was 22,813 men and 3,259 women

For every 10 middle school students in the us, 6 play sports. If there are 956 students how many play?
Answer:
About 573.6 or 574 would be the answer if you wanted it rounded.
Step-by-step explanation:
I found this by dividing 6 by 10 since for every ten student 6 play sports.
So I divide 6 by 10 and then I multiplied the result by 956 and found the answer to the equation.
So if there was 956 students then about 574 students would play sports.

2. A phone company charges a base fee of $12 per month plus an additional charge per minute. The
monthly phone cost C can be represented by this equation: C = 12 +a.m, where a is the additional
charge per minute, and m is the number of minutes used.
Which equation can be used to find the # of minutes a customer used if we know and a and C?
A. m = (C-12)
B. m = (C - 12)-a
C. m = C - 12a
(C-12)
D. m =
a
E. m = 8-12
Given:
The monthly phone cost C can be represented by this equation:
[tex]C=12+a\cdot m[/tex]
where, a is the additional charge per minute, and m is the number of minutes used.
To find:
The equation can be used to find the number of minutes a customer used if we know and a and C.
Solution:
We have,
[tex]C=12+a\cdot m[/tex]
We need to isolate m on one side.
Subtract 12 from both sides.
[tex]C-12=a\cdot m[/tex]
Divide both sides by a.
[tex]\dfrac{C-12}{a}=\dfrac{a\cdot m}{a}[/tex]
[tex]\dfrac{C-12}{a}=m[/tex]
[tex]m=\dfrac{C-12}{a}[/tex]
The options are not in proper format.
Therefore, the required equation is [tex]m=\dfrac{C-12}{a}[/tex].
PLZ ANSWER WILL GIVE BRAINLIEST TO CORRECT ANSWER!!! World renowned ice cream entrepreneurs Sydney and Eden produce two types of premium dairy ice cream products: Syd n’ Edy’s Chocolate Concussion and Vanilla Brain Freeze. Their chocolate ice cream requires 6 oz milk and 8 oz of peanuts per pint size container while the vanilla option requires 9 oz milk and 5 oz peanuts. Sydney and Eden currently enjoy a surplus of all other ingredients required for their ice cream but only have 360 oz of milk and 400 oz of peanuts for this limited production run. Given that the entrepreneurs charge $5 for each container of Chocolate Concussion and $7 for each Vanilla Brain Freeze, how many of each type should Sydney and Eden produce in order to maximize their profit and what is the maximum? Feel free to approximate to the nearest tenth of a pint as necessary.
A. 40 pints of vanilla brain freeze
B.42.9 pints of chocolate concussion and 11.4 pints of vanilla brain freeze
C.50 pints of chocolate concussion
D.They should not make any ice cream
In order to maximize the profit [tex]50[/tex] pints of chocolate concussion should produce.
What is linear programming?" Linear programming is defined as it represents the extreme value of the given linear function with given subject to constraints."
According to the question,
[tex]'x'[/tex] represents the number of chocolate concussion
[tex]'y'[/tex] represents the number of Vanilla Brain Freeze
[tex]'z'[/tex] represents the maximize cost
As per the given condition of linear programming,
Maximize Cost [tex]z =5x + 7y[/tex]
Subject to constraint
[tex]6x + 9y \leq 360\\\\8x + 5y \leq 400\\\\x\geq 0, y\geq 0[/tex]
For
[tex]6x + 9y \leq 360[/tex]
[tex]x= 0 \implies y=40\\\\y=0 \implies x=60[/tex]
And
For
[tex]8x + 5y \leq 400\\\\x=0 \implies y=80\\\\y=0 \implies x= 50[/tex]
Cost for each value of given linear programming we have,
[tex](x, y) = (0,40) \\\\\implies z = 5(0) + 7(40)\\\\ \implies z = $280[/tex]
[tex](x, y) = (60,0) \\\\\implies z = 5(60) + 7(0)\\\\ \implies z = $300[/tex]
[tex](x, y) = (0,80) \\\\\implies z = 5(0) + 7(80)\\\\ \implies z = $560[/tex]
[tex](x, y) = (50,0) \\\\\implies z = 5(50) + 7(0)\\\\ \implies z = $250[/tex]

Step-by-step explanation:
Since XY bisects ∠ WXZ then ∠ WXY = ∠ YXZ , thus
7x - 7 = 5x + 3 ( subtract 5x from both sides )
2x - 7 = 3 ( add 7 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
(b)
∠ WXY = 7x - 7 = 7(5) - 7 = 35 - 7 = 28°
(c)
∠ YXZ = 5x + 3 = 5(5) + 3 = 25 + 3 = 28°
(d)
∠ WXZ = ∠ WXY + ∠ YXZ = 28° + 28° = 56°
