The scatter plot and line of best fit below show the length of 7 people's femur (the
long leg bone in the thigh) and their height in centimeters. What is the meaning of
the y-value on the line when x = 40?
Answers
Answer:
An expected height of 160.6 centimeters when the femur has a length of 40 centimeters.
Step-by-step explanation:
The line of best fit makes a prediction. In other words, it tells us what height to expect for any given femur length.
x represents femur length and y represents height, so the y-value on the line when x=40x is the expected height when the femur length is 40 cm.
Using the Regression model given, the meaning of the expression is " the expected height of the individual with a femur length of 40 would be about 160 cm
The regression model compares the relationship between the independent and dependent variable. Here, Femur length and height The height of the individual with a femur length of 40 cm would be about 160cm.Hence, the expected height of the individual with a femur length of 40 would be about 160 cm.

The angles are
vertical
X=
Answers
Answer:
x = 128
Step-by-step explanation:
Adjacent angles - Angles right next to each other. They share a common vertex
Vertical angles - angles that are vertically aligned with each other.
The angle that has a measure of 128 degrees and x are vertical angles
If you didn't know vertical angles are congruent so because one angle equals 128 degrees the other equals 128 degrees
x = 128
The given angle are the vertical angles and the measure of the angle x is 128°.
Given that,
To specify whether the angles are adjacent or vertical. Then find the value of x.
orientation of one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
Here,
By the observation, angle x and 128° are the vertical angles and by the property of the intersection of the line both are equal angles so the measure of angle x is also equal to 128°.
Thus, the given angle is the vertical angle and the measure of the angle x is 128°.

A telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members. The company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan. The number of phone subscribers x months after the plan was launched is modeled by the function below.
Answers
Answer:
450 x (1 + 0.5) ^ X = Phone subscribers
Step-by-step explanation:
Since a telecommunications company in a small town had 450 phone subscribers before they introduced a plan for newly joining members, and the company recorded an approximate 50% increase each month in the number of new phone subscribers, where they had one new subscriber at the start of the plan, to determine the number of phone subscribers x months after the plan was launched, the following function must be considered and solved:
450 x (1 + 0.5) ^ X = Phone subscribers
So, for example, in 3 months, the number of subscribers would be the following:
450 x (1 + 0.5) ^ 3 = 1,518.75
Thus, in 3 months, the company would have 1,518 subscribers.

11259.5
Step-by-step explanation:
25×386+3219÷2
Multiply 25 and 386 to get 9650.
9650+3219/2
Convert 9650 to fraction 19300/2.
19300/2+3219/2
Since 19300/2 and 3219/2 have the same denominator, add them by adding their numerators.
19300+3219/2
Add 19300 and 3219 to get 22519.
22519/2
Divide 22519 by 2 to get 11259.5.

Find the area and perimeter of a rectangle that has a length of (x + 24) and (x + 16). Show all work for full credit.
Answers
Answer:
Perimeter of rectangle = 4x + 80
Area = x² + 40x + 384
Step-by-step explanation:
Perimeter of rectangle = 2*(length + width)
= 2* (x + 24 + x + 16)
= 2*( x +x + 24 + 16) {Combine like terms}
= 2* (2x + 40)
Use Distributive property : a*(b +c) = a *b + a*c
= 2*2x + 2*40
= 4x + 80
Area of rectangle = length * width
= (x + 24) (x + 16) {use FOIL method}
= x*x + x*16 + 24*x + 24*16
= x² + 16x + 24x + 384 {Combine like terms}
= x² + 40x + 384
