how do you find the coefficient on a scatterplot?

Answers

Answer 1

Answer:

The correlation coefficient is determined by dividing the covariance by the product of the two variables' standard deviations. Standard deviation is a measure of the dispersion of data from its average. Covariance is a measure of how two variables change together.

Answers

Answer:

24 times 9.75 = $234

Step-by-step explanation:

Answer:

It would cost $39 to serve 24 people

Step-by-step explanation:

If the recipe makes enough stew for 6 people, and the ingredients cost $9.75, then for 24 people it will cost $x. You can write this statement as

6 people - $9.75,

24 people - $x.

Or as proportion,

6/24=9.75/x

Find x:

6·× =9.75·24,

x=9.75·24/6=9.75·4=39

Answer: It would cost $39 to serve 24 people

If each block sides are 1 cm long, what is the volume of this object?

Answers

4 cubic centimeters.

Brainliest would be great. Comment below if it helped!

Answer:

The volume for this object is 4.

Step-by-step explanation:

For each block, we need to multiply using the volume formula which is

Length x Width x Height

So, if the side lengths for all these blocks are 1. That means we would do 1x1x1 for every block. Since there are 4 blocks that means our equation for the whole object would be 1+1+1+1 or simply 1x4. And we all know the answer to our equation 1 x 4 is 4.

26: A (4,1)

Same as 25

The x value and y value have the same value in both equations

Answer:

x + y =5 .......eqn (1)

x - y =3 .......eqn(2)

using substitution method

x + y = 5

-

x - y = 3

0 + 2y=2

y = 2/2

y = 1

substitute y in egn(1)

x + 1 = 5

x = 5-1

x = 4

then (x, y) = (4,1)

Explain or show work to prove that the following equation is true.6 x 8 = 3 x 2 x 2 x 2 x 2

Answers

Answer:

see explanation

Step-by-step explanation:

To prove the equation id true, solve both sides and if they are equal then the equation is true.

left side = 6 × 8 = 48

right side = 3 × 2 × 2 × 2 × 2

               = 6 × 2 × 2 × 2

              = 12 × 2 × 2

              = 24 × 2

=             = 48

Since both sides are equal then the equation is true
