Michael uses a uniform probability model for an experiment using a deck of 45 cards. There are 15 blue card, 15 red cards, and 1
vampirchik [111]

Answer:

<em>P</em> = 2/3

Step-by-step explanation:

45 cards in all

15 blue

15 red

15 green

To figure out the probability of red and blue together, add red and blue.

15 + 15 = 30

Since the total is 45, this is how many 30 will be out of.

30 out of 45 = 30/45

Simplify 30/45 by dividing each side by 15

30 ÷ 15 = 2

45 ÷ 15 = 3

30/45 = 2/3

Write an equation of the line passing through the points (4,6) and (-2, - 18).
olga_2 [115]

Answer:

y = 4x – 10

Step-by-step explanation:

slope formula: m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }

point-slope formula: y-y_{1}=m\left(x-x_{1}\right)

  1. Use slope formula and plug in your numbers: m = \frac{-18-6}{-2-4 }
  2. Solve for slope m = 4
  3. Use the point-slope formula to solve for the equation: y-6=4\left(x-4\right)
  4. Solve and find equation: y=4x-10

Note: When given two points you only need to pick one for the point-slope formula! Best to choose the positive one so you don't have to deal with the negatives!

Hope this helps! Please give Brainliest!
