Answer:
The answer is 76.9 rounded or rounds.
Step-by-step explanation:
Solution
Given that:
Mean = μ = 72.5
Standard deviation = σ = 6.5
Now
By applying the standard normal table we have the following:
P(Z < z) = 75%
= P(Z < z)
= 0.75
Thus
z =0.67 by using the standard normal z table
Applying the z-score formula we have:
x = z * σ + μ
x = 0.67*6.5+72.5
x= 76.855 ≈ 76.9
Therefore the cutoff time is 76.9 rounds.
Question:
The graph represents the two companies' prices. What is the linear equation that represents each T-shirt company?
Answer:
1.) Shirt Box: y = 7.5x + 30
2.) Just Tees: y = 10.5x
Step-by-step explanation:
For Number -<u>One</u>- We do - 7.5 + 30 = 37.5
For Number -<u>Two</u>- We do - 10.5 <u>×</u> "X"
You See We have to solve for "X"
This is just to give the idea, and Kinda help Explain it. . .

It's quite easy to calculate - one meter is billion nanometers (1 000 000 000), so:
- 1.7 meters = 1 700 000 000 nanometers
- 1.52 meters = 1 520 000 000 nanometers
C because it says it equals itself, but it’s opposite. So that’s impossible.
