The scatterplot shows the number of minutes Tyler played in his last eight basketball games and the points he
scored in each game. Estimate the location of the line of best fit. About howmany points would Tyler score if he
played for 40 minutes?
The equation of the line is : Ŷ = -0.1667+0.5935X.
The estimated number of points that will be obtained if Tyler played for 40 minutes is 24 points
To obtain the location of the line of best fit, we wrote out the coordinates of the points on the graph :
(6, 10) ; (8, 18) ; (10, 17) ; (12, 20) ; (17, 21) ; (11, 23) ; (14, 25) ; (18, 30)
Using technology, we can estimate the line of best fit :
Using a linear regression solver :
Y :
6, 8, 10, 12, 17, 11, 14, 18
X:
10, 18, 17, 20, 21, 23, 25, 30
The equation of the regression line obtained is :
Ŷ = -0.1667+0.5935X
The Number of points of Tyler played for 40 minutes :
x = 40
Ŷ = -0.1667+0.5935(40)
Ŷ = 23.5733 = 24(nearest whole number).
The estimated number of points that will be obtained if Tyler played for 40 minutes is 24 points.

Suppose that an individual has a body fat percentage of 16.8% and weighs 152 pounds. How many pounds of his weight is made up of body fat? Round your answer to the nearest tenth.
Step-by-step explanation:

the width?
Let length be x

Step-by-step explanation:
let the length be X and breadth be 2x
p=2(l+b)
24=2(X+2x)
24=2x+4x
24=6x
24÷6=x

so,we know that
X=4 and 2x=2 X 4= 8

Answer:
The square root of 2 is between 1 and 2, so radical 2 is about 1.4.
Step-by-step explanation:
You can plot a 1 on the very left and a 2 on the very right of the number line.
Since there is no formal square root of 2, you have to estimate.
It has to be less than 2 because if you multiply 2 * 2 you get 4 and that's too big; we want to get 2.
It also has to be greater than 1 because 1 * 1 = 1 and that's too low.
I would estimate it to be right before the middle line.

Find WV 2X+26 2X+31
I'm not sure how to finish this problem or if I'm doing it right. Please help
Answer:
4
Step-by-step explanation:
Yes u are doing it right
So just find x first
2x + 26 + 2x +31 =13
4x + 57 = 13
4x = - 44
x = - 11
Since now u know x = - 11, and u know
WV =2X+26
So...
2x + 26
=2(-11) + 26
= - 22 + 26
= 4

Answer:
Number two: x > -9/2, x < 3/2
Number one: x is less than or equal to 3/4, x is greater than or equal to - 13/4
Step-by-step explanation:
Number one:
|4x+5| > 10-2
|4x+5| > 8
4x+5 > 8
-(4x+5) > 8
x > 3/4
x < -13/4
x > 3/4, x < -13/4
(all of these signs are greater than or equal to and less than or equal to)
Number two:
|2x+3| > -6
2x+3 > -6
-(2x+3) > -6
x > -9/2
x < 3/2
x> -9/2, x < 3/2

Please help with this question 10 points!!!!
which is parallel to the line y = -5/8x+6
Answer:
The answer lies in the gradient.
Step-by-step explanation:
The gradient in this equation is -5/8. If any line has the same gradient as the equation above they are parallel because they have the same slant or tilt. Gradient determines if a line is parallel between linear line graphs. If the gradient between two linear line graphs are equal that means that they are parallel.
First identify what is the gradient of a line. The gradient is usually the number that is multiplied with x. In this case (-5/8x), -5/8 is the gradient.

7. Find the perimeter of the figure.
x+12
x + 2
Answer:
The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.
