Answer: c. On average, a 1 percentage point difference in chemistry score is associated with a 0.919 percentage point difference in geometry score
Step-by-step explanation:
Given that:
Slope value = 0.91857341
The dependent and independent variables are ;
Dependent Variable: Geometry
Independent Variable: Chemistry
Slope is the rate of change in the dependent variable per unit change in the independent variable.
Hence, from the information given, we can conclude that for every 1% change in chemistry score (independent variable), there is a corresponding approximately 0.919% change in geometry score (dependent variable).
From the given data it can be concluded that on average, a 1 percentage point difference in chemistry score is associated with a 0.919 percentage point difference in geometry score. Hence option c) is correct.
Given :
She randomly samples 400 students who took both classes and records their final scores (out of 100 points). She carries out a simple linear regression, using the geometry grade as the response variable and the chemistry grade as the explanatory variable since the students take chemistry before geometry.Given the simple linear regression results that are:
The Dependent variable is Geometry.
The Independent variable is Chemistry.
Geometry = 3.6276926+0.91857341[tex]\times[/tex]Chemistry
Comparing the above equation with the slope-intercept form which is given by:
y = mx + c
Therefore, slope, m = 0.91857341.
It is also given that:
Sample size is 400
R2= 0.55808158
Estimate of error standard deviation: 9.417521
From the given data it can be concluded that on average, a 1 percentage point difference in chemistry score is associated with a 0.919 percentage point difference in geometry score. Hence option c) is correct.

Jason drew a triangle to explain the Triangle Sum Theorem and labeled the angles 1, 2, and 3
He tore each angle off the triangle so he could move the three angles around.
What should Jason do next to explain the Triangle Sum Theorem?
Jason should line up the angles next to each other as adjacent angles to show that the 3 angles together form a straight angle.
Jason should create a new triangle by moving the angles closer together to show that the 3 angles can create other triangles.
Jason should fold each angle in half to show each angle with one half of the measure it had in the triangle.
Jason should stack the angles on top of each other to show that the 3 angles have the same measures.
Answer:
A
Step-by-step explanation:
Well B is strange. You might get them to make one complementary angle, but that has nothing to do with the Triangle sum theorem.
C is true. He is getting similar triangles, but that does not prove the Triangle sum theorem. So -- don't choose C
D is just taking up space so you get 4 choices.
The answer should be A but the problem is the tips of the angles should all come to the same place. I think it does mean A, but it is a bit awkwardly worded.

Use the graph below to find the indicated function Value. y=f(x); f(4)
The value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The graph of the function is shown in the picture.
From the graph the value of f(4) can be evaluated as follows:
y = f(x)
Plug x = 4
y = f(4)
From the graph:
Draw a vertical line from point 3 on the x-axis and when it cuts the curve draw a horizontal line when the line cuts the y-axis note the point.
y = f(4) = 3
Thus, the value of f(4) is 3 if the graph of the function is shown in the picture, the answer is 3.

Find the surface area of the triangular prism. The base of the
prism is an isosceles triangle.
45 cm, 37cm, 35cm, 24cm
Answer:
5,250 cm²
Step-by-step explanation:
Surface area of triangular prism = bh + (s1 + s2 + s3)L
Where ,
b = 24 cm
h = 35 cm
s1 = 37 cm
s2 = 37 cm
s3 = 24 cm
L = 45 cm
Plug in the values
Surface area = 24*35 + (37 + 37 + 24)45
= 840 + 4,410
= 5,250 cm²
Can someone help me find the area of this shape.
Answer:
37 ft²
Step-by-step explanation:
The figure is composed of a triangle and a square
Therefore, area of the figure = area of the triangle + area of the square
= ½bh + s²
Where,
b = 1.5 + 4 + 1.5 = 7 ft
h = 6 ft
s = 4 ft
Plug in the values into the equation
Area of the figure = ½*7*6 + 4²
= 21 + 16
= 37 ft²

For a certain brand of tomato seeds, the seed package claims that it takes 87 days after planting for the tomato plants to produce fruit. Sarah, a botanist, wanted to know whether the mean number of days for the plants to produce fruit where she lives is different from 87 days. She planted 40 seeds and recorded the number of days for each plant to produce fruit. With all conditions for inference met, the hypothesis test was conducted at the significance level a = 0.05, and the test resulted in a p-value of 0.0752. ?
Which of the following is a correct conclusion?
A. Sarah has convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is greater than 87 days.
B. Sarah has convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.
C. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is greater than 87 days.
D. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.
E. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is equal to 87 days.
Answer:
D. Sarah does not have convincing statistical evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.
Step-by-step explanation:
The population mean, μ is given as 87
This population value is used to state the Null hypothesis ;
H0 : μ = 87
The alternative hypothesis is the opposite of the Null ; and hence, claims that the mean is different from the population mean, μ ≠ 87
H1: μ ≠ 87
The Decison level :
When Pvalue < α ; We reject the Null otherwise we fail to reject the null
The given p and α value :
P-value = 0.0752
α = 0.05
0.075 > 0.05 ; Hence ;
Pvalue > α ; We fail to reject the Null
We can thus conclude that there is not enough evidence to conclude that the population mean number of days for the plants to produce fruit is different from 87 days.

What is the perimeter of the track, in meters? Use tt 3.16 and round to the nearest hundredth of a meter
Answer:
The perimeter of the track is of 317 meters.
Step-by-step explanation:
Perimeter:
The perimeter of a figure is the sum of all its dimensions.
In this question:
The track is composed by two straights of 80m, and two half circles with a diameter of 50m.
Perimeter of a circle:
The perimeter of a circle with diameter d is of:
[tex]P = \pi d[/tex]
Track:
Two half circles, each with a diameter of 50m, plus two straight lines of 80m. So
[tex]P = \frac{2\pi}{2}(50) + 2*80) = 50\pi + 160 = 50*3.14 + 160 = 317[/tex]
The perimeter of the track is of 317 meters.

Sorry I did it wrong.
Answer:
(0, -5) and (-16, -17)
Step-by-step explanation:
You can plug in the points into the function to test them.
(0, -5)
3(0) - 4(-5) - 8 = 12
20 - 8 = 12
12 = 12
(8, 2)
3(8) - 4(2) - 8 = 12
24 - 8 - 8 = 12
8 ≠ 12
(-16, -17)
3(-16) - 4(-17) - 8 = 12
-48 + 68 - 8 = 12
12 = 12
3(-1) - 4(-8) - 8 = 12
-3 + 32 - 8 = 12
21 ≠ 12
3(-40) - 4(-34) - 8 = 12
-120 + 136 - 8 = 12
8 ≠ 12
