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.

The pounds of grapes left with seinna is 3.125 or pounds
Solution:
Given that Sienna has pounds of grapes
She eats pound and gives pounds to her brother
To find: pounds of grapes left with seinna
We can find the pounds of grapes left with seinna by subtracting the pounds of grapes she ate and pounds of grapes she gave to brother from the total pounds of grapes she had
Pounds of grapes left with seinna = total pounds of grapes - pounds of grapes she ate - pounds of grapes she gave to brother
Substituting the values we get,
Thus the pounds of grapes left with seinna is 3.125 or poundsStep-by-step explanation:
X= -a/f = z/mf + g/mf
-a is over f
+ z over mf
+ g over mf
The volume of the rectangular prism is 17 cubic units
<h3>How to determine the volume?</h3>
The given parameters are:
- Length = 5 units
- Width = 2 units
- Height = 1.7 units
The volume is calculated as:
Volume = Length * Width * Height
Substitute known values
Volume = 5 * 2 * 1.7
Evaluate
Volume = 17
Hence, the volume of the prism is 17 cubic units
