The coordinates of the midpoint of a segment with two endpoints ( 22, 4 ) and ( 15, 7 ) is ( 37/2, 11/2 ).
The center of a line segment is known as the midpoint. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
Consider the two endpoints of the segments as:
A( 22, 4 ) and B( 15, 7 )
Let M( x, y ) be the midpoint of the line segment.
Then AM = MB = ( 1/2 )AB
Therefore, the points will also the halfway from the midpoint.
Therefore,
M( x, y ) = ( 1/2 )A + ( 1/2 )B
M( x, y ) = 1/2( 22, 4 ) + ( 1/2 )( 15, 7 )
M( x, y ) = ( 11, 2 ) + ( 15/2, 7/2 )
M( x, y ) = ( 11 + 15/2, 2 + 7/2 )
M( x, y ) = ( 37/2, 11/2 )
Therefore, the coordinate of the midpoint of the line segment is ( 37/2, 11/2 ).

Is y = 2x² a linear or nonlinear function? Please explain.
A linear function has the form:
[tex]y=mx+b[/tex]where m is the slope and b is the y-intercept, bot constants.
As we see, the exponent of variable x is 1 for a linear function.
So, since the exponent in the given function y = 2x² is 2, this function is a nonlinear function.
In fact, it is a quadratic function.

Marbel surveyed 55 people to find out their favorite types of music the results shown in the bar graph
To find the correct option, we need to find, first, the rate of the population that chose each type of music. Then, when we sum the rates of the types in the correct answer, it should result in 40%.
The rate of population for each type of music is given by the number of peaple that chose this type, divided by the total amount of people (55):
Country: 15/55
Jazz: 12/55
Opera: 10/55
Roch: 18/55
In the first option, we have:

is this relation a function ? yes or noif no , identify two ordered pairs as proof.
A relation is said to be a function when each input value is related to only one output.
It can also be said that a function is a relation that has only output for any unique input.
In a function, each x-value is related to only one output.
From the relation given here, we have a straight-line graph. Here, each x-value is related to only one y-value.
Since each x-value is related to only one y-value, this relation is a function.

Answer:
24
Step-by-step explanation:
If ratio of blue to red is 3:4 or in fraction terms 3/4 then the ratio of blue to all Jolly ranchers = 3/(3+4) = 3/7
Since there are a total of 56, the number of blue ones = 56 x 3/7 = 24
Answer:
24
Step-by-step explanation:
Based on the given conditions, formulate: 56 x 3 divided by (3 + 4)
Calculate the product or quotient: 168/3+4
Calculate the sum or difference:168/7

The surface area of the entire cube is 40.5 square inches
Here, we want to get the surface area of a cube given the measure of the area of one of the faces
Looking at the net of a cube, we can identify six identical and equal-dimension faces
So to get the total surface area of the cube, we have to multiply the surface area of one of the faces by 6

If the average weight calculated by Val is 1380 pounds with standard deviation 50 of 100 cows, then Val's margin of error will be 9.80.
Given that average weight found by Val is 1380 pounds with standard deviation 50 of 100 cows.
We are required to find the margin of error of Val's data.
Margin of error is the difference between the actual data and the calculated data.
Margin of error=1.96*σ/[tex]\sqrt{n}[/tex]
In our case σ=50 and n is 100.
Margin of error=1.96*50/[tex]\sqrt{100}[/tex]
=1.96*50/10

Assume that adults have IQ scores that are normally distributed with a mean of μ=100 and a standard deviation σ=20. Find the probability that a randomly selected adult has an IQ less than 128.
The probability that the IQ is less than 128 is 0.91924
How to determine the probability?The given parameters about the distribution are
Mean value of the set of data, μ = 100Standard deviation value of the set of data σ = 20IQ value, x = 128The z-score of the data value is calculated as
z = (x - μ)/σ
Substitute the given parameters in the above equation
z = (128 - 100)/20
Evaluate
z = 1.4
The probability that the IQ is less than 128 is then calculated as:
P(x < 128) = P(z < 1.4)
From the z table of probabilities, we have;
P(x < 128) = 0.91924
Hence, the probability is 0.91924
