The profits of two different clothing factories can be modeled as shown, where
s
is the number of shirts produced at each factory.
Factory A:
−0.06s2+43s−1600
Factory B:
−0.04x2+32x−1500
a. Write a polynomial that represents the difference in the profits at the two plants.
Note: It should be s instead of x in profit of factory B.
Given:
Consider the profits of two different clothing factories can be modeled as shown, where s is the number of shirts produced at each factory.
Factory A : [tex]-0.06s^2+43s-1600[/tex]
Factory B : [tex]-0.04s^2+32s-1500[/tex]
To find:
The polynomial that represents the difference in the profits at the two plants.
Solution:
Let,
Factory A : [tex]P_1=-0.06s^2+43s-1600[/tex]
Factory B : [tex]P_2=-0.04s^2+32s-1500[/tex]
Difference in the profits at the two plants is
[tex]Difference= P_1-P_2[/tex]
[tex]Difference= -0.06s^2+43s-1600-(-0.04s^2+32s-1500)[/tex]
[tex]Difference= -0.06s^2+43s-1600+0.04s^2-32s+1500[/tex]
[tex]Difference= (-0.06s^2+0.04s^2)+(43s-32s)+(-1600+1500)[/tex]
[tex]Difference= -0.02s^2+11s-100[/tex]
Therefore, the required expression is [tex]-0.02s^2+11s-100[/tex].
Find the indicated probability. The age distribution of students at a community college is given below. Age (years) Number of students (f) 1109​ A student from the community college is selected at random. Find the probability that the student is at least 31. Round your answer to three decimal places.
Answer:
0.063 is the probability of at least 31 students.
Step-by-step explanation:
Solution:
Given:
The age distribution of students is given below:
Age (years) Number of students
Under 21 414
21 - 25 413
26 - 30 212
31 - 35 50
0ver 35 20
total 1109
A student from community college is selected at random.
The ratio of favorable outcomes numbers of that event is the probability of to the total number of possible outcomes in experiment.
Probability of at least 31 students:
Probability of At least 31 students = 31 or more than 31 students
P( 31 – 35) = n (31 – 35) + n (over 35) / n(T)
= 50 + 20 / 1109
= 70 / 1109
= 0.063
0.063 is the probability of at least 31 students.

Jamal read 1/11 of a book in 2/5 of an hour at this rate how long will it take him to read the entire book?
Answer:
264 minutes OR 4.4 hours OR 4 hours and 24 minutes (all the same)
Step-by-step explanation:
if he takes 2/5 of an hour to read the 1/11 of the book, he takes 24 minutes to read 1/11 of the book.
24 * 11 is 264.
Therefore he will take 264 minutes to finish the entire book.

Item 8 A container has peppermint gum and spearmint gum. There are 40 pieces of peppermint gum in the container and the ratio of peppermint gum to spearmint gum is 5 : 2. Find the number of pieces of spearmint gum in the container.
Answer:
16.
Step-by-step explanation:
Divide 40 by 5 (or what times five equals 40), equals 8. 2 (the ratio of spearmint gum) times 8 equals 16. There is 16 pieces of spearmint gum.

Graph the equation X=3 and y= -8
Answer:
Although I don't graph it myself, you can simply do it yourself. For the graph of x = 3, all you need is a vertical line a x = 3, likewise, for y = -8, all you need to do is draw a horizontal line at y = -8.

4. c
5. b
Step-by-step explanation:
Angle ST is equal to 7m, because it is the same length as the bottom of the other triangle.
Angle SU is equal to 8m, as we see on the left side of the first triangle.
m < R is equal to 46, because of the total.
m < Q is equal to 75 because of the measure inside the second triangle.
m < 5 is equal to 59 because of the measure inside the first triangle.

A card is drawn at random from a standard 52-card deck. Find the probability that the card is an ace or not a club.
Answer:
0.7692077
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of aces in a standard deck = 4
Number of clubs in a standard deck = 13
Probability = required outcome / Total possible outcomes
P(ace) = 4 / 52 = 0.0769
P(club) = 13 / 52 = 1/4 = 0.25
P(not club) = 1 - p(club) = 1 - 0.25 = 0.75
P(ace and not club) = 3/52 = 0.0576923
P(ace or not club) = p(ace) + p(not club) - p(ace and not club
= 0.0769 + 0.75 - 0.0576923
= 0.7692077

Answer:
8:15
Step-by-step explanation:
Because the two figures are similar, we know that one of them is enlarged.
So, the ratio would be the side of the smaller length to the side of the larger length.
In this case, 8 and 15 are both on the same side in terms of both figures, so you ratio would be 8:15

Answer:20
Step-by-step explanation:
solids quiz edg 2021
The number vertices does the polyhedron have is 20.
What is Polyhedron?A polyhedron is a three-dimensional structure in geometry that has flat, polygonal faces, edges that are straight, and sharp vertices. A convex polyhedron is made up of finitely many points that are not all on the same plane and has a convex hull. Convex polyhedra include shapes like cubes and pyramids.
Using Euler formula
F + V = E + 2
As, From the figure the faces = 7 and edges = 30
12 + V = 30 + 2
12 + V = 32
V = 32- 12
V= 20
