Answer:

y=-1/2x+3

Step-by-step explanation:

You're Y coordinate is going to equal the slope, or rise over run (aka rate of change.)

-1/2 is the rate of change, as the line goes up one, over negative two.

Then, add the Y-intercept, which is three, and you've got your equation!

A basketball player's probability of making a free throw is 0.9. When the player makes two free throws in a row, X is the number

GrogVix [38]

Answer:

0.81

Step-by-step explanation:

P(success) = 0.9

P(failure) = 1 - 0.9 = 0.1

Binomial probability:

P(X=n) = nCr (0.9)^n (0.1)^r

Here, n=2 and r=0:

P(X=2) = ₂C₀ (0.9)² (0.1)⁰

P(X=2) = 0.81

Find the distance between A(2, -9) and B(-5, 7) on a coordinate plane d=?

Kazeer [188]

Answer:

$d=17.4642$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(-5-2)^2+(7-(-9))^2}$

$d=\sqrt{(-7)^2+(7+9)^2}$

$d=\sqrt{49+(16)^2}$

$d=\sqrt{49+256}$

$d=\sqrt{305}$

$d=17.4642$
