U=
Answer: Um, the answer is U= –144.
Step-by-step explanation:
To find the minimum thickness of the oversized books, use the z-score formula and solve for x.
To find the minimum thickness of the oversized books on the library shelf, we need to determine the lower cutoff point that includes 20% of the books.
First, we need to find the z-score that corresponds to a cumulative probability of 0.20 from the normal distribution table. The z-score is approximately -0.8416.
Next, we can use the formula z = (x - μ) / σ to find the minimum thickness x. Plugging in the values, we have -0.8416 = (x - 8.3) / 0.6. Solving for x, we find x ≈ 7.9344 centimeters. Therefore, the minimum thickness of the oversized books is approximately 7.93 centimeters.

Plant 2 : P2 (x) = -0.02x^2 + 21x - 1700
Find polynomials representing the difference in profits between the companies. Find P1(x) - P2 (x) and P1 (x). Compare the two differences and draw conclusions. Show work and make a equation
P1(x) - P2(x) = -0.01x² + 4x + 200
This shows that P1(x) profit is less than P2(x).
P2(x) - P1x = 0.01x² - 4x - 200
This shows that P2(x) profit is more than P1(x).
Polynomial is an equation written as the sum of terms of the form kx^n.
where k and n are positive integers.
We have,
Plant 1:
P1 (x) = -0.03x² + 25x - 1500
Plant 2:
P2 (x) = -0.02x² + 21x - 1700
P1(x) - P2(x):
= -0.03x² + 25x - 1500 - (-0.02x² + 21x - 1700)
= -0.03x² + 25x - 1500 + 0.02x² - 21x + 1700
= -0.01x² + 4x + 200
For any x value, we will get a negative value.
This means,
P1(x) profit is less than P2(x).
P2(x) - P1x:
= -0.02x² + 21x - 1700 - (-0.03x² + 25x - 1500)
= -0.02x² + 21x - 1700 + 0.03x² - 25x + 1500
= 0.01x² - 4x - 200
For any x value, we will get a positive value.
This means,
P2(x) profit is more than P1(x).
Thus,
P1(x) - P2(x) shows that P1(x) profit is less than P2(x).
P2(x) - P1x shows that P2(x) profit is more than P1(x).
