Yes it is divisible by both 3 and 37
A company sells widgets. The amount of profit, y, made by the
company, is related to the selling price of each widget, x, by the given
equation. Using this equation, find out the maximum amount of profit
the company can make, to the nearest dollar.
y = -4x^2 + 183x – 1247
Answer:
846.06 units
Step-by-step explanation:
The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation as follows :
[tex]y = -4x^2 + 183x- 1247[/tex] ...(1)
We need to find out the maximum amount of profit the company can make.
For maximum profit put dy/dx = 0
So,
[tex]\dfrac{d}{dx}(-4x^2 + 183x- 1247)=0\\\\-8x+183=0\\\\x=\dfrac{183}{8}\\\\x=22.87[/tex]
Put x = 22.87 in equation (1). So,
[tex]y = -4(22.87)^2 + 183(22.87)- 1247\\\\=846.06[/tex]
So, the maximum profit is 846.06 units.

3. The table below lists the colored marbles in a bag. Match the theoretical probabilities for drawing a single marble with the correct marble color. Marble Color Number of Marbles blue 12 red 6 yellow 21 black 8 green 11 1. 19% 2. 14% 3. 36% 4. 21% 5. 10% a.red b.black c.green d.red e.yellow
Answer:
Blue = 12/58 * 100% = 20.68 = 21%
Red = 6/58 * 100 = 10.34 = 10%
Yellow = 21/58 * 100 = 36.20 = 36%
Black = 8/58 * 100 = 13.79 = 14%
Green = 11/58 * 100 = 18.96 = 19%
Step-by-step explanation:
Given the table :
Marble_color ____ Number of marbles
Blue ___________ 12
Red ___________ 6
Yellow _________ 21
Black __________ 8
Green _________ 11
Theoretical probability % = (number of favorable outcome / number of total possible outcomes)
Total possible outcomes = (12+6+21+8+11) = 58
Blue = 12/58 * 100% = 20.68 = 21%
Red = 6/58 * 100 = 10.34 = 10%
Yellow = 21/58 * 100 = 36.20 = 36%
Black = 8/58 * 100 = 13.79 = 14%
Green = 11/58 * 100 = 18.96 = 19%

24. If you invest $4000 in an account that gains 7% interest each year, how long will it take for there
to be $9000 in the account?
(5 Points)
Answer:So, since it is continuously, we need to think of PERT
A=P\times e^{rt}
So, we just plug our numbers in to solve for T
8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t

The chance of rain is 20%, the chance of it being sunny is 60%, and the chance of it
being sunny and rainy at the same time is 10%. Calculate, the probability that it is
either sunny or rainy.
Answer:
0.6 = 60% probability that it is either sunny or rainy.
Step-by-step explanation:
We solve this question treating these events as Venn probabilities.
I am going to say that:
Event A: Rain
Event B: Sun
The chance of rain is 20%
This means that [tex]P(A) = 0.2[/tex]
The chance of it being sunny is 60%
This means that [tex]P(B) = 0.6[/tex]
The chance of it being sunny and rainy at the same time is 10%.
This means that [tex]P(A \cap B) = 0.1[/tex]
Calculate, the probability that it is either sunny or rainy.
This is:
[tex]P = P(A) + P(B) - 2P(A \cap B) = 0.2 + 0.6 - 0.2 = 0.6[/tex]
0.6 = 60% probability that it is either sunny or rainy.

What is the volume of a rectangular prism whose length is 2x+1 units, width is x-2 units, and whose height is 3x units?
6x^3-9x^2-6x cubic units
6x^2-9x-6 square units
6x^3-9x^2+6x cubic units
6x^3-15x^2+6x cubic units
Answer:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
Step-by-step explanation:
The volume of a rectangular prism of length L, depth W and height H is
V = L * W * H.
Thus,
in this case,
V = (2x + 1)(x - 2)(3x).
The order in which we multiply these quantities together is immaterial.
Working from left to right, we get:
V = (2x^2 - 3x - 2)(3x), and then:
V = 6x^3 - 9x^2 - 6x (which matches the third answer choice)
The value of a house increases by 20% each year.
It is valued at $20000 today.
a) What will it be worth in two years' time?
b)What was it worth one year ago?
Answer:
a. $28,800
b. $16,000
Step-by-step explanation:
A.
20,000 * 20% = 4,000
so thats how much more it will be next year
add that together
20,000 + 4,000 = 24,000
so thats one year from now and we have to find two
multiply 20% times next years value
24,000 * 20% = 4,800
so add that to 24,000
24,000 + 4,800 = 28,800
so in two years the value will be $28,800
B.
20,000 * 20% = 4,000
so thats how much less it was worth one year ago
so you have to subtract it
20,000 - 4,000 = 16,000
so it was worth $16,000 one year ago

What is the length of DC? Show work.
Answer:
DC = 3
Step-by-step explanation:
Based on triangle similarity theorem, we would have the following equation:
[tex] \frac{AD}{AC} = \frac{AE}{AB} [/tex]
Plug in the values
[tex] \frac{9}{9 + DC} = \frac{12}{12 + 4} [/tex]
[tex] \frac{9}{9 + DC} = \frac{12}{16} [/tex]
[tex] \frac{9}{9 + DC} = \frac{3}{4} [/tex]
Cross multiply
3(9 + DC) = 9×4
27 + 3DC = 36
Subtract 27 from each side
3DC = 36 - 27
3DC = 9
Divide both sides by 3
DC = 9/3
DC = 3

The value of x for the two lengths of the diagonals is 1.
What is a diagonal?A diagonal in geometry is a line segment that connects two polygonal or polyhedral vertices when they are not on the same edge. Any sloping line is known as a diagonal informally.
Geometry is the area of mathematics that deals with the characteristics of space and the shapes of particular things as well as the interactions between them in space.
Given that the two segment values are 2x + 4 and 7x - 1. The value of x will be calculated as,
2x+4 = 7x-1
5x = 5
x = 1
Hence, the value of x is 1.

-6x+5y=1 and 6x+4y=10.substitution
Answer:
(23/27, 11/9)
Step-by-step explanation:
Given the simultaneous equation;
-6x+5y=1..... 1
6x+4y=10.... 2
Add both equations
5y + 4y = 1+10
9y = 11
y = 11/9
Substitute y = 11/9 into 1;
From 1;
-6x+5y=1.
-6x + 5(11/9) = 1
-6x + 55/9 = 1
-6x = 1- 55/9
-6x = (9-55)/9
-6x = -46/9
x = -46/-54
x = 23/27
The solution to the system of equation is (23/27, 11/9)
