Answer:
the numerical value of the correlation between percent of classes attended and grade index is r = 0.4
Step-by-step explanation:
Given the data in the question;
we know that;
the coefficient of determination is r²
while the correlation coefficient is defined as r = √(r²)
The coefficient of determination tells us the percentage of the variation in y by the corresponding variation in x.
Now, given that class attendance explained 16% of the variation in grade index among the students.
so
coefficient of determination is r² = 16%
The correlation coefficient between percent of classes attended and grade index will be;
r = √(r²)
r = √( 16% )
r = √( 0.16 )
r = 0.4
Therefore, the numerical value of the correlation between percent of classes attended and grade index is r = 0.4

An automobile manufacturing plant produced vehicles today: were sedans, were trucks, and were motorcycles. Plant managers are going to select two of these vehicles for a thorough inspection. The first vehicle will be selected at random, and then the second vehicle will be selected at random from the remaining vehicles. What is the probability that the first vehicle selected is a sedan and the second vehicle is a truck?
Question is incomplete :
Number of each type of vehicle produced isn't given :
An automobile manufacturing plant produced 32 vehicles today: 10 were sedans, 11 were vans, and 11 were trucks. Plant managers are going to choose two of these vehicles for thorough inspection. The first vehicle will be chosen at random, and then the second vehicle will be chosen at random from the remaining vehicles.
What is the probability that the first vehicle selected is a sedan and the second vehicle is a truck?
Answer:
55 / 496
Step-by-step explanation:
Total possible outcomes = 32
Number of Sedan = 10
Vans = 11
Trucks = 11
P(first selection is sedan) :
Number of sedan / total number of vehicles
= 10 /32 = 0.3125
P(second is a truck)
Total possible outcomes = 32 - 1 = 31
Number of trucks = 11 / 31
(10/32 * 11/31)
= (10*11) / (32*31)
= 110 / 992
= 55 /496

Any Netflix suggestions to watch?
Answer:

Step-by-step explanation:
Mr Smith has $109 to spend in parking and admission to the zoo. the parking is $7 and admission is $15.50 per person including tax. write and solve equation to determine the number of people he can bring to the zoo
Answer:
He can bring 6 people to the zoo.
Step-by-step explanation:
7 + 15.50x = 109
subtract 7 from both sides
15.50x = 102
divide by 15.50 on both sides
x = 6.58064516129 = 6 people
Determine whether the two expressions are equivalent. If so, tell
what property is applied. If not, explain why.
5 x ( 6 x 3 ) and ( 5 x 6 ) x 3
Answer:
Yes, they are equivalent.
Step-by-step explanation:
5*(6*3) equals 90.
(5*6)*3 also equals 90.
When multiplying and adding, it doesn't matter where you place the numbers, they still equal the same. If you look at the two problems you see they are the same numbers, just in different places.

Answer:
F) The solution to the system is (1/3,3)
Step-by-step explanation:
Let's attempt to solve this system:
Given:
9x+2y=9
-3x+y=2
Set up elimination:
9x+2y=9
3(-3x+y=2)
9x+2y=9
-9x+3y=6
________
5y=15
y=3
Plug y=3 into one of the original equations:
-3x+y=2
-3x+(3)=2
-3x+3=2
-3x=-1
x=1/3
So it is clear that there is only one solution pair that works. The correct answer is F) The solution to the system is (1/3,3)

solve each proportion algebraically. show your work. 6.1/x = 2/3
Answer:
x = 9.15
Step-by-step explanation:
6.1/x = 2/3
multiply both sides by x and 3
3(6.1) = 2x
2x = 18.3
divide both sides by 2
x = 9.15
Answer:
x=9.15
Step-by-step explanation:
6.1 x 3= X times 2
18.3 = X times 2
X times 2 =18.3
(X times 2) divided by 2 = 18.3/2
which gives the answer
x=9.15

Find the midpoint of the line segment with these endpoints: (-3,-8), (9,3)
Answer:
Step-by-step explanation:
(3,-5/2)
The midpoint of the line segment with these endpoints (-3, -8) and (9, 3) will be (0, 0.5).
What is the mid-point of the line segment?Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).
Then the coordinate of the mid-point of the line segment is given as,
(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]
The endpoints of the line segment are given below.
(-3, -8) and (9, 3)
The midpoint of the line segment is calculated as,
(x, y) = [(-3 + 3) / 2, (-8 + 9)/ 2]
(x, y) = (0/2, 1/2)
(x, y) = (0, 0.5)
The midpoint of the line fragment with these endpoints (- 3, - 8) and (9, 3) will be (0, 0.5).
More about the mid-point of the line segment link is given below.

Find the following amount What is 25% of 4
Answer:
1
Step-by-step explanation:
Answer 1
Step-by-step explanation:
Given the points M(−6,−4) and T(9,16) find the y-coordinate of the point Q on the directed line segment MT so that MQ:QT=2:3
Given the coordinates M (-6, -4) and T (9, 16)
If the coordinates are divided in the ratio 2:3 then a = 2, b = 3
The y coordinate of the point Q will be expressed as;
Y = ay1+by2/a+b
From the coordinates, y1 = -4 y2 = 16
Y = 2(-4)+3(16)/2+3
Y = -8+48/5
Y = 40/5
Y = 8
Hence the y-coordinate of the point Q is 8

Answer:

Step-by-step explanation:
since they are similar
they will be divided by 9 for example
we have 54 on the left but if you divide it by 9 we get 6 which is on the right
then we have 27 on the left if you divide by 9 we get 3 which is on the right
so then we have 18 and a missing number
so we divide 18/9 and get 2
