A local high school track team claims that the average time it takes a member of their team to run one mile is 6.75 minutes, with a standard deviation of 1.25 minutes. Hank, a member of the track team, ran one mile in 6.5 minutes. Given that the data is approximately normal, standardize the times and find the area under the normal curve above the standardized time.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
