An engineer wants to determine how the weight of a gas-powered car, x, affects gas mileage, y. The accompanying data represent the weights of various domestic cars and their miles per gallon in the city for the most recent model year. Complete parts (a) through (d) below. Weight (pounds), x Miles per Gallon, y 3773 17 3793 16 2706 25 3645 20 3308 22 2908 24 3675 17 2687 24 3522 18 3827 16 a) Find the least-squares regression line treating weight as the explanatory variable and miles per gallon as the response variable y= x+( ) A certain gas-powered car weighs 3511 pounds and gets 18 miles per gallon. Is the miles per gallon of this car above average or below average for cars of this weight? The estimated average miles per gallon for cars of this weight is ( ) miles per gallon. The miles per gallon of this car is average for cars of this weight.
Answers
Answer:
y= 0.007x- 4.945
The estimated average miles per gallon for cars of this weight is (20.829 or 21 ) miles per gallon.
The miles per gallon of this car below (18 < 20.829) the average for cars of this weight.
Step-by-step explanation:

3308 22 72,776
2908 24 69,792

∑y²=4075; ∑y=199; ∑x²= 116,406,174 ; ∑x=33,844 ; ∑xy=659,808
b= n∑XY - (∑X)(∑Y)/ n∑X² - (∑X)²
b=(10) (659,808) - (33,844)(199)/ 10 (116,406,174) - 1,145,416,336
b=6,598,080- 6,734,956/ 1,164,061,740 -1,145,416,336
b=136,876/18,645,404
b= 0.007341
a= Y`- bX`
a= 19.9- (0.007341) (3384.4)
a= 19.9 -24.845
a=-4.945
Y^= -4.945+ ( 0.007341) X
y= 0.007x- 4.945
Putting the values
y= 0.007x- 4.945
18 = 0.007(3511) - 4.945
18< 20.829
The estimated average miles per gallon for cars of this weight is (20.829 or 21 ) miles per gallon.
The miles per gallon of this car below (18 < 20.829) the average for cars of this weight.

When looking for a job micah is told that the monthly salary has a range of 876 he also knows that the starting salary is 1,793 per month what is the maximum amount of money that micah can earn in this position?
Answers
Answer:
2669
Step-by-step explanation:
Given that :
Salary range = 876
Starting salary = 1793 monthly
The starting salary represents the minimum amount Micah can earn monthly
Therefore, the amount of money much can earn can be calculated thus :
Recall :
Range = maximum - minimum
876 = maximum - 1793
876 + 1793 = maximum
Maximum = 2669
Hence, the maximum salary Micha can earn is 2669 monthly

what is the median and mode for the numbers 40, 28, 24, 37, 43, 26, 30, 36

It is even no of obs
Therefore the two middle obs are 30,36
Therefore median 30+36/2
Therefore median 66/2
Therefore median is 33
There is no mode in the following obs
If you are helped with my answer pls tag me brianliest I really want it
THANK YOU.......
The median of the numbers is M = 33 and the mode is not defined
What is Median?The median is the value that's exactly in the middle of a data set when it is ordered. It's a measure of central tendency that separates the lowest 50% from the highest 50% of values. The steps for finding the median differ depending on whether you have an odd or an even number of data points
Arrange the data points from smallest to largest.
If the number of data points is odd, the median is the middle data point in the list.
If the number of data points is even, the median is the average of the two middle data points in the list.
Given data ,
Let the set of numbers be represented as set A
Now , the value of A is
A = { 40, 28, 24, 37, 43, 26, 30, 36 }
Arranging the numbers in the ascending order , we get
A = { 24 , 26 , 28 , 30 , 36 , 37 , 40 , 43 }
Now , the total number of elements in the set A = 8
So , the median is the average of the two middle data points in the list.
M = ( 30 + 36 ) / 2
M = 33
The mode of the numbers is the numbers that appears the most often
So , mode is not defined
Hence , the median is M = 33

The constant -10 represents the maximum number of cheeseburgers sold by the food stall at the funfair. C. The constant -10 represents the total money earned by setting up the food stall. D. The constant -10 represents the cost of each cheeseburger at the food stall.
Answers
Answer:
In the expression [tex]\dfrac{60 \cdot x}{x + 3} -10[/tex] what the constant term -10 represents is;
A. The constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold
Step-by-step explanation:
Whereby the expression is as given in a similar question which is presented as follows;
[tex]\dfrac{60 \cdot x}{x + 3} -10[/tex]
Where the expression represents the total money earned when a food stall is set up at a fair where 'x' stands for the number of cheeseburgers sold
Then when no cheeseburger were sold, x = 0, such at the start just after setting up the food stall, we then have;
[tex]\dfrac{60 \times 0}{0 + 3} -10 = -10[/tex]
Therefore, the money earned at the start = -10
∴ The money spent at the start = 10
Therefore, the constant -10 represents the cost of setting up the food stall even if no cheeseburgers were sold.

find the inverse of h(x)= -x^5+2 step by step
Answers
Hi there!
[tex]\large\boxed{y = \sqrt[5]{-(x-2)}}[/tex]
[tex]h(x) = -x^{5} + 2[/tex]
Rewrite h(x) as y:
[tex]y = -x^5 + 2[/tex]
Switch the x and y variables:
[tex]x = -y^{5} + 2[/tex]
Isolate y by subtracting 2 from both sides:
[tex]x - 2 = -y^5[/tex]
Multiply both sides by -1:
[tex]-(x-2) = y^5[/tex]
Take the 5th root of both sides:
[tex]y = \sqrt[5]{-(x-2)}[/tex]
