The correlation coefficient r between a child age x and the number of minutes spent doing homework each day y is 0.694.What percent of the variation?

A. 30.6%
B. 48.2%
C. 51.8%
D. 69.4%

Answers

The final answer to your question is that the percent variation of  the correlation coefficient between a child age x and the number of minutes spent doing homework each day y with r = 0.694 is C. 51.8%.
Hope my answer would be a great help for you.

Answer:

The answer is 48.2%

Step-by-step explanation:

The correlation coefficient r between a child age x and the number of minutes spent doing homework each day y is 0.694 i.e r=0.694

Now, we have to find percent of the variation.

The coefficient of determination isr^(2)

The square of r(correlation coefficient) is the percent of variation that is explained by the dependent variable.

If r=0.694 ⇒r^(2)= (0.694)^(2)=0.482 this means that 48.2% of variation in dependent variable.

Look at the first Model It on the previous page. Why do you double 8 to find theamount of money Julie will have on Day 4?.

Answers

Answer:

Doubling a number means multiplying it by 2. If there is a pattern or rule that suggests doubling is necessary, it could be based on a specific mathematical relationship or calculation.

Step-by-step explanation:

For example, if there is a consistent pattern of doubling in a mathematical sequence, it could indicate exponential growth or a specific mathematical operation being applied. In some scenarios, doubling may be necessary to account for the accumulation or growth of a value over time.

It is important to note that without the specific context or information provided on the previous page, it is difficult to give a definitive explanation for why 8 is being doubled to find Julie's money on Day 4.

The vertices of parallelogram ABCD are A(2,1),B(3,4),C(5,3), and D(4,0). ABCD is reflected over the x-axis to create parallelogram QRST. What are the coordinates of QRST?A
Q(−2,1),R(−3,4),S(−5,3),T(−4,0)

B
Q(−2,−1),R(−3,−4),S(−5,−3),T(−4,0)

C
Q(1,2),R(4,3),S(3,5),T(0,4)

D
Q(2,−1),R(3,−4),S(5,−3),T(4,0)

Answers

Answer:

The correct answer is:

D)   Q(2,1)  R(3,-4) S(5,-3) T(4,0)

Step-by-step explanation:

When you reflect over the x-axis the vertices of the parallelogram, the y -coordinates is multiplying by -1.

Then the new coordinates of the parallelogram are:

Q(2,-1)  R(3,-4) S(5,-3) T(-4,0)

When i was two, my brother was half my age
now i am 100. what is my brothers age

Answers

When you were 2, your brother were 2/2=1. So you are one year older than your brother.
If you are 100 now, then your brother is 100-1=99.
99 as 2 halved is 1 so 100-1= 99

Solve for x.6 – 3(2x – 4) = 2(1 + x)

A. -2
B. 0
C. -1
D. 2

Answers

6 - 3(2x - 4) = 2(1 + x)   Use the Distributive Property (Multiply the number on the                                outside of the parentheses by all of the numbers in                                            parentheses to get rid of the parentheses.)
6 - 6x + 12 = 2 + 2x     Isolate the variable. Start by subtracting 2 from both                                           sides.
6 - 6x + 12 - 2 = 2x     Combine like terms. (6, 12, and -2)
16 - 6x = 2x                Add 6x to both sides to get all the x's on one side of the                                    equation.
16 = 8x                       Divide both sides by 8.
2 = x

X equals D. 2 .
Hi Brainiac

6 - 3(2x - 4) = 2(1 + x)
Use the distributive property
6+(-3)(2x)+(-3)(-4) = (2)(1)+(2)(x)
6 - 6x + 12 = 2 + 2x
Now we need to combine like terms
-6x +(6+12) = 2x +2
-6x + 18 = 2x + 2
-6x -2x = 2 - 18
-8x = -16
x = -16/-8
x= 2

I hope that's help... If you have any further questions please let me know. Good night :)

What is the perimeter of a triangle that has two sides measuring 7 centimeters and a third side measuring 9 centimeters?

Answers

The answer is 23cm just add the sides

The perimeter is the sum of all of the lengths of the sides. To find the perimeter, add together the length of each side.

For this triangle, our side lengths are 7, 7, and  9.

7 + 7 = 14

14 + 9 = 23

The perimeter of a triangle that has two sides measuring 7 centimeters and a third side measuring 9 centimeters is 23 centimeters.

Hope this helps!! :)
