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.
Answer: The point (0,0)
This point is also known as the origin
The reason why is because every direct variation equation is of the form y = k*x
where k is some fixed number
If we plugged in x = 0 it leads to y = k*x = k*0 = 0. So (x,y) = (0,0)

Zoe gives Dev 7 shells
If you subtract 55-7 you get 48 and if you add 9+7 you get 16 and when you multiply 16(3) you get 48 so there’s the answer
