sandra swims the 100-meter freestyle for her school’s swim team. her state’s ranking system awards 3 points for first place, 2 points for second, 1 point for third, and 0 points if she does not place. her coach used her statistics from last season to design a simulation using a random number generator to predict how many points she would receive in her first race this season.   what is sandra’s expected value of points awarded for a race?
integer value point awarded frequency
1-8 3 20
9-15 2 12
16-19 1 6
20 0 2

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)

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

but there’s no any figure there!
