Answer:
Total number of marbles = 18
Number of green marbles = 8
Number of ways to choose 3 green marbles = [tex]8C_3[/tex]
Number of ways to choose 3 marbles from the total 18 marbles= [tex]18C_3[/tex]
Probability 0f choose 3 green from 18 marbles
= [tex]\frac{8C_3}{18C_3}[/tex]
= 0.0686 = 6.9%

9f^2–10– 1+2f^2+ – 7f^2
(NO LINKS)
(LINKS WILL BE REPORTED)
Answer:
4f² - 11
Step-by-step explanation:
first group the like terms
9f²-2f²-7f² is all like terms
-10-1 are like terms
9f²-2f²-7f² -10-1
4f² - 11
2.) Combine like terms and simplify the expression: 2x +
5y+ 7x
Your answer
Answer:
9x + 5y
Step-by-step explanation:
Here, in 2x + 5y+ 7x, the 'like terms' are 2x and 7x, and the sum of these terms is 9x. Thus, 2x + 5y+ 7x becomes 9x + 5y.
Which expression means the same as "the quotient of 8 less than x and 4"?
Answer:
(x - 8) -4

Using the picture, find the measure of arc GR. (GK is the diameter)
Answer:
48°
Step-by-step explanation:
Given that GK is the diameter of the circle ;
Then GK which is the half of the circle is 360/2 = 180 (Angle at a Point = 360°)
Diameter =half of the entire circle = 360 /2 = 180
GK = 180°
GK =GR + KR = 180
KR = 132°
180 = GR + 132
GR = 180 - 132
GR = 48°

How much larger is the volume of a triangular prism when you double the height of the prism?
9514 1404 393
Answer:
2 times
Step-by-step explanation:
Other things remaining the same, the volume of any prism is proportional to its height. If you double the height, it is like having two prisms of the same size. The volume doubles. The new volume is 2 times the original volume.

9514 1404 393
Answer:
A = 2B = 13C = 6Step-by-step explanation:
In expanded form, the quadratic is ...
(2x +1)(x +6) = 2x(x +6) +1(x +6) = 2x² +12x +x +6
= 2x² +13x +6
Comparing this to ...
Ax² +Bx +C
we see that ...
A = 2B = 13C = 6Answer:
the answer is
a=2
b=13
c=6

Step-by-step explanation:
Kilgore's Deli is a small delicatessen located near a major university. Kilgore does a large walk-in carry-out lunch business. The deli offers three luncheon chili specials, Wimpy, Dial 911, Fire Bowl. At the beginning of the day, Kilgore needs to decide how much of each special to make (he always sells out of whatever he makes).
The profit on one serving of Wimpy is $0.6, on one serving of Dial 911 is $0.55, and on one serving of Fire Bowl is $0.65.
The following table shows the required ingredients to make one serving of each chili special, and the available amount of each ingredient for today :
Ingredient Required ingredient for each serving of Wimpy Required ingredient for each serving of Dial 911 Required ingredient for each serving of Fire Bowl Available Amount
Beef (lbs) 1 1 1.5 15
Onions (cup) 2 2 2 20
Special Sauce (oz) 5 2 3 90
Hot Sauce (oz) 0 5 6 60
Based on the historical sales data, Kilgore's Deli has the following considerations:
the number of servings for Fire Bowl must be at least 10% of the total number of servings for all three luncheon chili specials.
the number of servings for Fire Bowl, however, cannot exceed the number of Dial 911 by more than 3.
the available number of servings for Dial 911 must be at least 2.
(1.1) Develop the linear programming model to help determine the number of servings of Wimpy, Dial 911, and Fire Bowl to make in order to maximize his profit today. Type your algebraic formulation in the specified area in Q1 tab of the Excel template. Note you will not get full credits without including the algebraic formulation.
(1.2) Solve your LP model in Excel and fill in the following blanks (show your work in Q1 tab):
The optimal number of servings of Wimpy is
The optimal number of servings of Dial 911 is
The optimal number of servings of Fire Bowl is
The maximum possible profit is
Is there any leftover of ingredients as a result of this optimal solution? if yes, enter the amount. Otherwise, just type 0.
Amount of beef leftover
Amount of onion leftover
Amount of special sauce leftover
Amount of hot sauce leftover
Answer:
z (max) = 6.15
x₁ = 1 x₂ = 3 x₃ = 6
Amount of beef leftover 2 lb
Amount of onions leftover 0
Amount of Special Sauce leftover 61
Amount of Hot Sauce leftover 9
Step-by-step explanation:
Ingredients Beef Onions Special S Hot S Profit
Wimpy (x₁) 1 2 5 0 0.6
Dial 911 (x₂) 1 2 2 5 0.55
Fire Bowl (x₃) 1.5 2 3 6 0.65
Available 15 20 90 60
Objective Function z:
z = 0.6*x₁ + 0.55*x₂ + 0.65*x₃ to maximize
Subject to:
1) Quantity of beef : 15
x₁ + x₂ + 1.5*x₃ ≤ 15
2) Quantity of onions: 20
2*x₁ + 2*x₂ + 2*x₃ ≤ 20
3) Quantity of Special sauce: 90
5*x₁ + 2*x₂ + 3*x₃ ≤ 90
4) Quantity of hot sauce: 60
0*x₁ + 5*x₂ + 6*x₃ ≤ 60
5) Condition: The number of servings for Fire Bowl must be at least 10% of the total number of servings for all three luncheon chili specials.
x₃ ≥ 0.1 ( x₁ + x₂ + x₃ ) or x₃ ≥ 0.1*x₁ + 0.1 *x₂ + 0.1*x₃
x₃ - 0.1*x₁ - 0.1 *x₂ - 0.1*x₃ ≥ 0
- 0.1*x₁ - 0.1 *x₂ + 0.9 *x₃ ≥ 0
6)Condition: The number of servings for Fire Bowl, however, cannot exceed the number of Dial 911 by more than 3.
x₃ - x₂ ≤ 3
7)the available number of servings for Dial 911 must be at least 2.
x₂ ≥ 2
General constraints:
x₁ ≥ 0 x₃ ≥ 0 all integers
With on-line solver solution is:
z (max) = 6.15
x₁ = 1 x₂ = 3 x₃ = 6
By sbstitution on the constraints
1) x₁ + x₂ + 1.5*x₃ ≤ 15 1 + 3 + 9 = 13
Amount of beef leftover 2 lb
2) 2*x₁ + 2*x₂ + 2*x₃ ≤ 20 2 + 6 + 12 = 20
Amount of onions leftover 0
3) 5*x₁ + 2*x₂ + 3*x₃ ≤ 90 5 + 6 + 18 = 29
Amount of Special Sauce leftover 61
4)0*x₁ + 5*x₂ + 6*x₃ ≤ 60 15 + 36 = 51
Amount of Hot Sauce leftover 9

Let the function [tex]f(x)= 3x + 2[/tex] and [tex]g(x) = \frac{x+3}{2x-10}[/tex] , determine:
Answer:
Given
f(x) = 3x + 2g(x) = (x + 3) / (2x - 10)#1
g · f(x) = g(f(x)) = (3x + 2 + 3)/ (2(3x + 2) - 10) = (3x + 5) / (6x - 6)#2
f · g(x) = f(g(x)) = 3[(3x + 2) / (2x - 10)] + 2 = (9x + 6) / (2x - 10) + 2 = (9x + 6 + 4x - 20)/ (2x - 10) = (13x - 14) / (2x - 10)What is the magnitude of -3+ 4i?
Answer:
5
Step-by-step explanation:
d² = (-3)² + 4²
d² = 9 + 16
d² = 25
d = 5
Answer:
The magnitude is 5.
Step-by-step explanation:
(I’m going to be using r to represent the magnitude)
r^2= (-3)^2+4^2
r^2= 9+16
r^2= 25
r = 5

Jennifer wants to borrow $ 20, 000 . Her bank offers a 7.1% interest rate. She can afford $500 a month for loan payments. What should be the length of her loan to the nearest tenth of a year
Answer:
4.2 years
Step-by-step explanation:
20000(.071)t ≤ 500(12)
1420t ≤ 6000
t = 4.2
Her loan is 4.2 years long to the nearest tenth of a year.
How is compound interest determined?To calculate compound interest, multiply the original loan principle by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the loan's principal plus compound interest.Compound interest is one of the most useful financial concepts, which states that the interest you earn each year is added to your principal so that the balance not only grows, but grows at an increasing rate. It serves as the foundation for everything, including a person's personal savings strategy and the long-term growth of the stock market.Therefore,
20000(.071)t ≤ 500(12)
1420t ≤ 6000
t = 4.2
Hence, Her loan is 4.2 years long to the nearest tenth of a year.
