Answer:

y = - 3x - 3

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 3) and (x₂, y₂ ) = (6, -21) ← 2 points from the table

m = \frac{-21-3}{6+2} = \frac{-24}{8} = - 3

y = - 3x + b ← is the partial equation

To find b substitute any other point from the table into the partial equation

using (2, - 9), then

- 9 = - 6 + b ⇒ b = - 9 + 6 = - 3

y = - 3x - 3 ← linear relationship

Mrs. Nestler enjoys listening to classical music. She has the following audio CDs by her favorite composers in her collection: 4
ivolga24 [154]

Answer:

10.55% probability

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.

1 Bach CD, from a set of 4.

1 Beethoven CD, from a set of 6.

1 Brahms CD, from a set of 3.

1 Handel CD, from a set of 2.

So, D=144

4 CDs from a set of 4+6+3+2 = 15.

So, T= 1365

p= D/T= 144/1365 = 0.1055

10.55% probability that she will choose one by each composer
