The question is incomplete, the complete question is;
A scatterplot is produced to compare the number of hours that students study to their test scores. There are 25 data points, each representing a different student. The scatterplot shows a grouping of points rising from left to right. Which statement could be true?
a. There is no relationship between the number of hours that students study and their test scores because the scatterplot does not have a cluster.
b. As the number of hours of studying increases, test scores decrease because the scatterplot has a cluster that increases from left to right.
c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
d. The number of hours that students study is equal to the test scores because the scatterplot does not show a cluster.
Answer:
c. As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
Step-by-step explanation:
Though we can't see the scatter plot but it makes sense from option c that as the number of hours of studying increases, test scores increase.
That option even stated that the cluster of points increases from left to right. If the scatterplot has a cluster that increases from left to right, then it follows that the test scores actually increases positively with the number of study hours.

how many times larger then 2x10² is 2x10⁸
Answer:
1,000,000 times larger
Step-by-step explanation:
2 x [tex]10^{8}[/tex] = 200,000,000
2 x [tex]10^{2}[/tex] = 200
200,000,000 divided by 200 is 1,000,000
It can also be solved by subtracting the exponents from 10. Then dividing the two number being put the scientific notation.
[tex]10^{8} - 10^{2}[/tex] = [tex]10^{6[/tex]
2 ÷ 2 = 1
Now solve:
1 x [tex]10^{6[/tex] = 1,000,000

Stephanie is giving a presentation to a new client. It took her 1713 minutes to finish a 13-slide presentation. She took the same amount of time on each slide. How long did she spend on each slide?
Answer:
Time taken per slides = 131.77 minutes.
Step-by-step explanation:
Given the following data;
Total time, t = 1713 mins
Number of slides, n = 13
To find the amount of time spent on each slides;
Time taken per slides = t/n
Substituting into the equation, we have;
Time taken per slides = 1713/13
Time taken per slides = 131.77 minutes.
Therefore, the amount of time Stephanie spent on each slide is 131.77 minutes.
It took Stephanie about 1 minute to finish each slide of the 13-slide presentation.
EquationEquation is used to show the relationship between two or more numbers and variables.
Le x represent the amount of time spent on each slide.
Given that she spent 13 minutes to finish a 13-slide presentation. Therefore:
13x = 13Divide through by 13:
13x/13 = 13/13x = 1It took Stephanie about 1 minute to finish each slide of the 13-slide presentation.

Aubree invested $500 into a mutual fund that paid 3% interest each year compounded annually. Find the value of the mutual fund in 12 years.
Answer:
FV= $712.88
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $500
Number of periods (n)= 12 years
Interest rate (i)= 3% compounded annually
To calculate the future value, we need to use the following formula:
FV= PV*(1+i)^n
FV= 500*(1.03^12)
FV= $712.88

Answer:
y = -3/4x -1
Step-by-step explanation:
The given equation is in the slope-intercept form, which lets you see that its slope is 4/3.
The slope of the perpendicular line will be the negative reciprocal of this:
-3/4
Then the slope-intercept form equation will be ...
y = -3/4x +b . . . . . . for some b
We can find the value of b that makes the line go through (4, -4) by using those values in this equation.
-4 = -3/4(4) +b
-4 +3 = b . . . . . . . . add 3
-1 = b
Then the equation you're looking for is ...
y = -3/4x -1

Answer:
x^3−2x2+4x+3=x2−5x+15+−41x+3
Step-by-step explanation:
1.Divide the leading term of the dividend by the leading term of the divisor: x3x=x2.
Write down the calculated result in the upper part of the table.
Multiply it by the divisor: x2(x+3)=x3+3x2.
Subtract the dividend from the obtained result: (x3−2x2+4)−(x3+3x2)=−5x2+4.
2.Divide the leading term of the obtained remainder by the leading term of the divisor: −5x2x=−5x.
Write down the calculated result in the upper part of the table.
Multiply it by the divisor: −5x(x+3)=−5x2−15x.
Subtract the remainder from the obtained result: (−5x2+4)−(−5x2−15x)=15x
3.Divide the leading term of the obtained remainder by the leading term of the divisor: 15xx=15.
Write down the calculated result in the upper part of the table.
Multiply it by the divisor: 15(x+3)=15x+45.
Subtract the remainder from the obtained result: (15x+4)−(15x+45)=−41.

Please discuss the relationship between the value of "a" in a quadratic function [y = a(x - h)2 + k or y = ax2 + bx + c] and the distance the focus is from the vertex. Please give examples to support your conclusion.
Please Help!
Answer:
The given equations are;
y = a·(x - h)² + k or y = a·x² + b·x + c
We have;
(x - h)² = 4·p·(y - k),
Where;
(h, k) are the x, and y coordinates of the vertex
p = The distance from the focus to vertex distance;
Comparing, we have;
y - k = a·(x - h)²
(y - k)/a = (x - h)²
(x - h)² = 4·p·(y - k)
4·p·(y - k) = (x - h)²
∴ 4·p = 1/a
p = 1/(4·a)
Therefore, the focus to vertex distance inversely proportional to the value of a
The distance of every point on the parabola is equidistant from the directrix and the focus
Therefore, the equation of the directrix is y = k - p
For example, we have;
y = 2·x² + 3·x + 1
h = -b/2a = -3/4
k = (4ac - b²)/4a = (4×2×1 - 3²)/(4×2) = -1/8
The coordinate of the focus is (h, k + p) = (-3/4, -1/8 + 1/8) = (-3/4, 0)
The directrix, y = k - p = -1/8 - 1/8 = -1/4
For a point x = 2, we have, y = 2·2² + 3·2 + 1 = 15
The coordinate of the point is (2, 15)
The distance of the point from the directrix = 15 - (-1/4) = 15 + 1/4 = 15.25
The distance of the point from the focus is √((2 - (-3/4))² + (15 - 0)²) = 15.25
Therefore, all points on the parabola have equal distances from the focus and the directrix
