In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie
Lunna [17]

Answer:

PART A

  • Red: 7/29
  • Blue: 8/29
  • Yellow: 5/29
  • Green: 9/29

PART B

  • Red or blue: 7/29 + 8/29 = 15/29
  • Yellow or green: 5/29 + 9/29 = 14/29
  • Blue or yellow or green: 8/29 + 5/29 + 9/29 = 22/29

Explanation:

In this case where the question is asking or <u>OR</u> and the events are <u>mutually exclusive</u> (Mutually exclusive meaning you can't attain two or three different colors in one pick), the compound probability is the sum of the probability of each component event (Probability of Red <u>OR</u> Blue = P(Red) + P(Blue) = 7/29 + 8/29 = 15/29)

Plz help me with this question!!
Snowcat [4.5K]

Answer:

B)x^3

Explanation:

Given,

(x^8)/(x^2)=y^12

We can simplify the following by bringing the (x^2) above the division line which makes the power negative.

(x^8)*(x^-2)=y^12

or,(x^(8-2))=y^12

or,x^6=y^12 .........(1)

The question is, (y^8)/(y^2)=

Simplifying the question,

(y^(8-2))

or,y^6

Now,from ...(1),

x^6=y^12

or,(x^3)^2=(y^6)^2

Removing the squares,

x^3=y^6

Thus,we get the answer of the question,

(y^8)/(y^2)=y^6=x^3
