Answer:
C: 31% of the variation in the GPA is accounted for by the linear relationship with number of absences.
Step-by-step explanation:
right on edge
The correct interpretation of the value of r² in this context is 31% of the variation in the GPA is accounted for by the linear relationship with the number of absences.
The interpretation of the value of r² in the context of the relationship between a student's number of absences (x) and their grade point average (GPA) (y).
First, what is r²? The coefficient of determination, denoted as r², is a statistical measure that represents the proportion of the variance (variation) in the dependent variable (GPA) .
That can be explained or predicted by the independent variable (number of absences) in a linear regression model.
Here, the value of r² is 31%. This means that 31% of the total variability in the GPA scores of the 15 randomly selected students can be explained by the linear relationship with the number of absences.
31% of the differences in GPAs among the students can be attributed to the differences in their number of absences.
The remaining percentage (100% - 31% = 69%) represents the unexplained or residual variation in the GPA scores.
This unexplained variation could be due to other factors not considered in the linear relationship, such as individual study habits, natural academic ability,
or other variables that were not part of the data analysis.
The interpretation is that 31% of the variation in the GPA scores can be accounted for by the linear relationship with the number of absences, while 69% of the variation remains unexplained by this relationship.

Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.
A'(-5, -2.5)B'(2.5, 5)C'(5, -10)Step-by-step explanation:
Given the vertices of ΔABC
A(-2, -1)B(1, 2)C(2, -4)Given that ΔA'B'C' is a dilation of ΔABC with a scale factor of 2.5 and the center of dilation (0, 0).
We know that when the scale factor > 1, then the image is enlarged.
The formula to determine the dilation with a scale factor of 2.5.
P(x, y) → P'(2.5x, 2.5y)
Here, P' is the image of P, and the vertices of the image is dilated by a scale factor of 2.5.
In other words, the vertices of the image can be obtained by multiplying the vertices of the original triangle with 2.5.
Thus,
P(x, y) → P'(2.5x, 2.5y)
A(-2, -1) → P'(2.5(-2), 2.5(-1)) = A'(-5, -2.5)
B(1, 2) → B'(2.5(1), 2.5(2)) = B'(2.5, 5)
C(2, -4) → C'(2.5(2), 2.5(-4)) = C'(5, -10)
Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.
A'(-5, -2.5)B'(2.5, 5)C'(5, -10)The supplement of an angle is three times the measure of the angle.
What is the measure of the angle?
The measure of the angle is degrees.
The measure of the supplement of the angle is degrees.
Answer: The angle equals 45 ∘ and the supplement is 135 ∘
Explanation:
Since the supplement is three times the angle, we can say s = 3 a
Since we know the supplement is
180 − a , we can plug that in.
180 - a = 3a
180 = 4 a (add a to both sides)
45 = a (divide both sides by 4)
Since we know the angle now, all we have to do is multiply it times 3 to find the supplement.
45 × 3 = 135

Answer:
68, 17, $17
Step-by-step explanation:
filling in the first blank using the chart. Money made for 4 sweatshirts is $68
68/4=17, this is the unit price, meaning the amount it would cost for one sweatshirt. Thats where we get the next blank's answer. 17/1 and since we found the unit price, we already answered the last question, $17 per sweatshirt.
What is the circumference?
16 yd
Answer:
16 yd
Step-by-step explanation:
I will assume 16 yards is the diameter, meaning 8 is the radius.
Circumference is 2πr, or the diameter itself. So, the circumference is 16.
I'm still not sure what measure 16 yd is, or what circumference of a shape you're looking for. Reply to my answer and I'll fix it.
The distribution of height of adult american women is approximately normal with a mean of 65.5 inches and a standard deviation of 2.5 inches what percentage of women are taller than 70.5 inches?
Answer:
2.275%
Step-by-step explanation:
We start by calculating the z-score
Mathematically;
z-score = (x-mean)SD
here, x = 70.5
mean = 65.5
SD = 2.5
Substituting these values;
z = (70.5-65.5)/2.5
= 5/2.5 = 2
So we want to calculate the probability that;
P( z> 2)
We check the standard normal distribution table for this
That will be
0.02275
In percentage, this is 2.275 %

Find the value of x. Write your answer in simplest radical form, if necessary.
The value of 'x' or the length of the base of the triangle is [tex]\sqrt{141}[/tex] units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know, In right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.
The given triangle has a hypotenuse of 25 units and a height of 22 units.
Therefore,
Hypotenuse² = Base² + Height².
Base² = Hypotenuse² - Height².
Base = [tex]\sqrt{Hypotenuse^2 - Height^2}[/tex].
Base = [tex]\sqrt{25^2 - 22^2}[/tex].
Base = [tex]\sqrt{625 - 484}[/tex].
Base = [tex]\sqrt{141}[/tex].
So, The length of the base is [tex]\sqrt{141}[/tex] units.

If we can solve for the value of x. Then the solution would be one only for system of linear equations.

When the equation is false or rather say that both sides have different number or value then there won't be any solutions.

write a rational number which has no reciprocal or multiplicative inverse.
Answer:
0.
Step-by-step explanation:
0 is the only number that has no reciprocal or multiplicative inverse.
A reciprocal / multiplicative inverse of a number means a number that when multiplied by the original number will equate to 1.
However, no matter what you multiply with 0, it will never be 1.
Hence, the answer is 0.
