Answer:
y = -3x + 5
Step-by-step explanation:
Given the exponential function:

The starting point is found when x = 0.
So, let's substitute x by 0.

Answer: The starting point is (0, 1.004).
Step-by-step explanation:
We know that,

Where,
X = raw score = 84
μ = mean = 68
σ = standard deviation = 10
Putting the values,

The percent of his sales that were less than or equal to 84 inches, is

Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
We know a or b != 0
but a-b==0 so both are the same unknown number
b/a must = 1
so
a/b is equivalent to b/a as a/b=1 as well.
So the last answer choice.
