Kelsey received 9 birthday gifts from her friends. Three gifts were wrapped in yellow paper, 3 gifts were wrapped in red paper, 2 gifts were wrapped in purple paper, and
1 gift was wrapped in orange paper. What is the probability that the first gift Kelsey
opened was wrapped in purple paper?

2/9

Step-by-step explanation:

From the question, we are told that

Kelsey received 9 birthday gifts from her friends and that three of the gifts were wrapped in yellow

paper. Also, 3 gifts were wrapped in red paper, 2 gifts were wrapped in purple paper, while the remaining

1 gift was wrapped in orange paper.

The probability that the first gift will be in purple paper will be the number of gifts in purple paper divided by the total number of gifts. This will be:

= 2/9

2

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
