[tex]4.302(20) - 3.293 = 82.747[/tex]
The mean value of the response variable is 82.747.
What is Regression line?Linear Regression calculates the equation of the line that is the best fit for the given data points. Linear regression models a linear relationship between the input variable x and the output variable y.
Here, given regression line;
y= 4.302x - 3.293 ...............(i)
Now, value of x is given; x = 20
Put the value of x in equation (i), we get
y = 4.302 X 20 - 3.293
y = 86.04 - 3.293
y = 82.747
Thus, the mean value of the response variable is 82.747.

Answer:
The answer is B.
Step-by-step explanation:
4 is a multiple of 2, which explains the reasoning of answer choice B.
Answer choice A is wrong because 2 is Not a multiple of 4.
Answer choices C and D are incorrect because it takes multiple steps to solve for x and substitute into the other equation. They claim that it takes on step to solve for x, but it would take 2 steps to solve for x.

Sandy has around $245 in her pocket but she thinks she could have up to $25 more or $25 less. Write and solve an absolute value equation that can show the maximum and minimum amount of money that Sandy has in her pocket.
Answer:
The absolute value equation is |x - 245| = 25The maximum amount of money in Sandy's pocket is $270The minimum amount of money in Sandy's pocket is $215Step-by-step explanation:
The absolute value equation for the amount of money in Sandy's pocket is given as;
|x - 245| = 25
The equation for the maximum amount of money in Sandy's pocket is given as;
x - 245 = 25
x = 25 + 245
x = $270
The equation for the minimum amount of money in Sandy's pocket is given as;
x - 245 = -25
x = -25 + 245
x = $215

CallmeCarson lol
Answer:
860$
Step-by-step explanation:
In order to find the answer to this question you need to multiply the amount of hours Carson worked to the amount of days he worked and then you need to multiply that by the amount he gets paid per hour.
[tex]21.50 = ph[/tex]
[tex]hours=8[/tex]
[tex]days = 5[/tex]
[tex]8\times5=40[/tex]
So he worked 40 hours a week

Therefore Mr.Carson has made 860$ that week.

Lorenzo increases all the prices on his restaurant menu by 8%
Before the increase, the price of a dessert was £4.25
Work out the price of the dessert after the increase.
Answer:
4.59
Step-by-step explanation:
The question requires the price of the desert after the increase
price of the dessert after the increase is £4.59
Price before increase = £4.25
Percentage increase = 8%
Amount of increase = 8% of 4.25
= 8/100 × 4.25
= 0.08 × 4.25
= £0.34
Price after increase = Price before increase + Amount of increase
= £4.25 + £0.34
= £4.59

A bag contains two coins, one for which the probability of heads is equal to 1 and one for which the probability of heads is equal to p. A coin is selected at random, and three independent tosses of this coin result in three heads. What is the probability that a further independent toss of this coin will produce a head?a. p4/1 + p3.b. p3 - p2/1 + p3.c. p3/1 - p.d. 1/1 + p3.e. 1 + p4/1 + p3.
Answer: Option E is the correct answer; (1 + p⁴) / (1 + p³)
Step-by-step explanation:
P (3 head) = P(first and 3 heads) + P(second coin and 3 heads)
= (1/2)×1³ + (1/2)× p³ = (1/2) × (1 + p³)
therefore P(first coin given 3 heads) = (1/2)×1³/ ((1/2)×(1 + p³))
= 1 / (1 + p³)
Also P( second coin given 3 heads) = p³ /(1 + p³)
therefore P(4th toss in heads given first 3 are heads) will be;
= P(first and 4th toss heads) + P(second and 4th toss heads)
=(1/( 1 + p³ )) × 1 + p³ / (1+p³) × p
= (1 + p⁴) / (1 + p³)
Therefore Option E is the correct answer

Connor works in a department store selling clothing. He makes a guaranteed salary of $300 per week, but is paid a commission on top of his base salary equal to 5% of his total sales for the week. How much would Connor make in a week in which he made $2175 in sales? How much would Connor make in a week if he made xx dollars in sales?
Earnings when selling $2175:??
Earnings when selling $x: ??
Answer:
[tex]Earnings = 308.75[/tex] ---- (a)
[tex]Earnings = 300 + 0.05x[/tex] -- (b)
Step-by-step explanation:
Given
[tex]Base\ Salary = 300[/tex]
[tex]Commission = 5\%[/tex]
Solving (a): Sales of $2175 in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * 2175[/tex]
[tex]Earnings = 300 + 108.75[/tex]
[tex]Earnings = 308.75[/tex]
Solving (b): Sales of $x in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * x[/tex]
Convert percent to decimal
[tex]Earnings = 300 + 0.05 * x[/tex]
[tex]Earnings = 300 + 0.05x[/tex]
