Suppose a normal distribution has a mean of 34 and a standard deviation of 2. What is the probability that a data value is between 31 and 37? Round your answer to the nearest tenth of a percent.A.86.6%B.88.6%C.87.6%D. 85.6%

step-by-step explanation:

5x+2x=49

7x=49

x=7. 35 apples

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)
