Which of the following statements concerning the linear correlation coefficient are true?

I: If the linear correlation coefficient for two variables is zero, then there is no relationship between the variables.
II: If the slope of the regression line is negative, then the linear correlation coefficient is negative.
III: The value of the linear correlation coefficient always lies between –1 and 1.
IV: A linear correlation coefficient of 0.62 suggests a stronger linear relationship than a linear correlation coefficient of –0.82.

Problem: (6.5/2)^2 = ?
I got 42.25 over 4, but its wrong. So I did 6.5 times 6.5(to square it) and got 42.25. Then I did 2 times 2 and got 4. So, the answer would be 42.25 over 4, right?

Answers

Answer:

10.5625 is the answer I got.

Step-by-step explanation:

I used the process PEMDAS for this equation.

(6.5÷2)^2

6.5÷2= 3.25^2

Now you bring down the new quotient and multiply it by itself.

3.25 x 3.25= 10.5625

the answer is 10.56

Answer:

Melinda saves 2 less dollars than Marcus each week.

Step-by-step explanation:

Y = 12x + 75 is Melinda's equation. Y = 14x + 25 is Marcus's equation. First we'll disregard how much money they have saved already to see how much they save weekly. So Melinda's new equation is Y = 12x, and Marcus's new equation is Y = 14x. Now we'll do Marcus's equation (14x) - Melinda's equation (12x) to see how much more money Marcus saves each week, which will in turn will tell us how much less money Melinda saves each week.

14 x - 12x = 2. (x-x=0) This tells us Marcus saves 2 more dollars than Melinda each week.

Which gives us our answer, Melinda saves 2 less dollars than Marcus each week.

This composite figure is made of three identical cylinders that are connected together

Radius:3 Height:8

Answers

The surface are of a cylinder is

SA = 2πr2 + 2πrh

where:
r = radius
h = height

This formula comes from adding the areas of the surfaces of the cylinder. It has two flat circular faces and a rounded face.

If we cut the cylinder from the circular face symmetrically, the surface area for one piece will be

SA = 2[(πr2)/2] + (2πr/2)h + 2rh

We will have 2-half flat circular faces, a flat rectangular surface, and half of the rounded surface.

Simplify the SA formula.

SA = πr2 + πrh + 2rh
SA = r(πr + πh + 2h)

Substitute the values into this formula.

SA = 3(3π + 8π + (2*8))
SA = 3(11π + 16)
SA = 33π + 48
SA = 151.67 cm2

Since we have 2 pieces, multiply this result by 2.

2(151.67 cm2) = 303.34 cm2.

The total area is 303.34 cm2.

Ravi had 124 dollars to begin with. He just spent b dollars. Using b , write an expression for the number of dollars he has left.

Answers

We know that Ravi has 124$, but we don’t need how much he spent! So, for the money he’s spent we are using B to represent it. The way I see the expression is:

124 - B = T

B is how much money he spent.
T is his total after.

I hope this helped! Good luck :D

An expression for the number of dollars he has left is: 124 - B = T

1000000 x 1000000= what?

Answers

Answer:

1000000000000

Step-by-step explanation:

1000000x1000000=1000000000000

The solution of the expression 1000000 x 1000000 in exponential form is  [tex]10^{12}[/tex].

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

Example = 4y, 3x+4.

The way of writing or expressing a number in powers is called exponent.

Example: [tex]3^2[/tex]

Here, 3 is the base and 3 is the power.

The given expression can be written in the index  or exponential form as:

1000000 x 1000000 = [tex]10^6 \times 10^6[/tex]

Since, the given exponent has the same base.

So, using the law of exponent, it can be written as:

[tex]a^m + a^n = a^{(m+n)[/tex]

[tex]10^6 \times 10^6 = 10^{(6+6)}[/tex]

                  = [tex]10 ^{12}[/tex]

Thus, the solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].

What is 5x-y=1/4 in slope intercept form? PLEASE give me step by step explanation and why you did what. Thank you! ❤

Answers

Answer:

y=5x-1/4

Step-by-step explanation:

The slope-intercept form would be y=mx+b, where y would be on one side. In this case, we would have to move y to one side. You can add y on both sides to move it on the right. Then, you would subtract 1/4 on both sides to move it to the left so that y is on its own side. Then the equation would equal y=5x-1/4, where 5 = m and -1/4 = b.
