The computer regression output includes the R-squared values, and adjusted R-squared values as well as other important values
a) The equation of the least-squares regression line is [tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]
b) The correlation coefficient for the sample is approximately 0.351
c) The slope gives the increase in the attendance per increase in wins
Reasons:
a) From the computer regression output, we have;
The y-intercept and the slope are given in the Coef column
The y-intercept = 10835
The slope = 235
The equation of the least-squares regression line is therefore
[tex]\underline {\hat y = 235 \cdot x + 10835}[/tex]
b) The square of the correlation coefficient, is given in the table as R-sq = 12.29% = 0.1229
Therefore, the correlation coefficient, r = √(0.1229) ≈ 0.351
The correlation coefficient for the sample, r ≈ 0.351
c) The slope of the least squares regression line indicates that as the number of attending increases by 235 for each increase in wins

In order for the data in the table to represent a linear function with a rate of change of +5, what must be the value of a?
a = 3
a = 8
a = 18
a = 33
Answer:
18
Step-by-step explanation:
if it adds 5 then 13+5=18
Answer:
a = 18
Step-by-step explanation:
We know from the table that our function must be y = 5x -2. We get this information by plugging in 13 = 5(3) - b and solving for b. Now that we have our function we plug in 4.
y = 5(4) -2
y = 20 - 2
y = 18

(it’s abt perpendicular, parallel and skew lines)
Answer:
Perpendicular
Step-by-step explanation:
Both lines intersect and form a right angle when they intersected each other. Non co-planar means essentially means "on different planes", but both lines do lie on the same plane. Parallel lines don't intersect at all! However lines a and d are intersecting. Skewed means neither parallel nor perpendicular (meaning they intersect and don't form a right angle).
Answer:
It would be perpendicular.
Step-by-step explanation:
Perpendicular lines form a 90-degree angle.
Skew lines are on different planes and do not intersect.
Since A and D intersect with a 90-degree angle they're perpendicular.

Answer:
1st Q: C. Algebraic Expression; it consists of numbers and a variable.
2nd Q: D. The number of times Chris washes the car.
Step-by-step explanation:
1st Question:
Numerical Expression: Contains numbers and operations. Numerical expressions are your typical 2 + 2 equations. The ones you start learning in Kindergarten with just numbers and different operations such as addition, subtraction, division, and multiplication.
EX: 108 - 24 = ?
? = 84
Algebraic Expression: Contains numbers, operations, and variables. They are the same as normal, numerical expressions with the exception that it also has letters, or variables.
EX: 2x + 3 = 7
x = 2
__________________________________
2nd Question:
Amount Chris earns per wash: $10.00
# of times Chris washes the car: x
So 10x means what...?
10 = earns per wash
x = times washed the car
Multiply 10 by x to find the total Chris earns for the number of times he washes the car, x.
(Just as a reference, this would be counted as an Algebraic Expression).
Hope this helps! :)

A painter earns $15 per hour. What is the minimum number of hours he must work to earn at least $200? Write an inequality to represent this situation and solve. Show your work.
PLEASE DO STEP BY STEP BECAUSE IT NEEDS ME TO SHOW MY WORK!
BEST ANSWER GETS BRAINLIEST! :) TYSM I NEED ANSWER ASAP
Answer:
200<=15x
divide by 15
You have to work at least 13 1/3 hours to earn $200
<= means greater than or equal to
Step-by-step explanation:
The minimum number of hours to earn at least $200 is 14
How to determine the minimum number of hours?Let the number of hours be x.
Given that hourly rate is $15, and he needs to earn at least $200;
The inequality of the scenario is:
15x >= 200
Divide both sides by 200
x >= 13.33
The smallest integer greater than 13.33 is 14.
So, we have:
x = 14
Hence, the minimum number of hours is 14

|2s-7| is bigger than or equal to -1
The inequality expression of the statement is |2s - 7| >= -1
What are inequality expressions?Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal
How to represent the statement as an expression?The mathematical statement is given as
|2s - 7| is bigger than or equal to -1
The term "bigger than or equal" means greater than or equal to
In mathematics, the term greater than or equal to is represented as >=
So, we have the representation of the mathematical statement to be
|2s - 7| >= -1
From the question, we are not instructed to simplify the expression
This means that we leave the expression |2s - 7| >= -1 unsimplified
Hence, the mathematical statement as an expression is |2s - 7| >= -1

let the graph of g be horizontal shrink by the factor of 2/3 followed by a translation 5 units left and 2 units down of the graph of f (x) =x ^ 2
1. horizontal shrink by factor of 2/3 means multiply outside the f(x) or outside the x^2 by 2/3:
(2/3)•f(x)
2. translation left 5 units means "x+5" inside:
(2/3) • f(x+5)
3. tranlate down 2 units means "-2" outside:

because of you do 5+2 = 7 then you minus 3 which you get 4.
the. if you have a production of around 10 you will get 7.
or you can do.
3+2 which is 5 and then you multiply that by 2 which is 10 and then you comprised that number therefore you will get 6 but you have to find X so we youndelie (think that's how u spell it) X which will equal to 1 and 6+1 is 7. once you get it it's quite simple
