Suppose that in the inventory problem, the storage cost depends on the maximum inventory size, rather than the average. This would be more realistic if, for example, the company had to build a warehouse large enough to hold the maxi- mum inventory, and the cost of storage was the same no matter how full or empty the warehouse was. Show that in this case the number of units that should be ordered or manufactured to minimize the total cost is q= âfM/k

Twenty-five students go to lunch. Pizza costs $3 and sandwiches cost $2. Twelve students buy pizza. What is the total amount of money spent on sandwiches?
Answer:
26.
Step-by-step explanation:
Take 25 and subtract 12 from it.
25 - 12 = 13
then take 13 and multiply it by 2.
13 x 2 = 16
what is the value of x ?
Answer:
Since we know that the sum of the two angles equal 180, we can add them together to equal 180 degrees.
2x+10+x+26=180
Combine like terms.
3x+36=180
Subtract 36 from both sides.
3x=144
Divide 3 from both sides.
x=48

pdf Ron, Sue, and Ted arrive at the beginning of a professor’s office hours. The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours. (a) What is the expected time until only one student remains? (b) For each student, find the probability they are the last student left. (c) What is the expected time until all three students are gone?
Answer:
a) 0.45 hours
b)
P( Ron ) = 7/12
P( sue ) = 4/15
P(Ted ) = 3/20
c) 1.22 hours
Step-by-step explanation:
Ron , sue and Ted
mean values = 1, 1/2 , 1/3 hours
a) determine the expected time until only one student remains
E(x) = 9/20 = 0.45 hours
b) Probability that each student is the last student left
P( Ron ) = 7/12
P( sue ) = 4/15
P(Ted ) = 3/20
C) Time until all students are gone
= 146 / 120 = 1.22 hours
attached below is the detailed solution
This question is based on the concept of probability.Therefore, the answers are as follows:
(a) 0.45 hours
[tex]\bold{(b) \, P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta}[/tex]
(c) 1.22 hours
Given:
The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.
According to the question,
The amount of time they will stay is exponentially distributed with means 1, 1/2, and 1/3 hours.
(a) The expected time until only one student remains,
[tex]E(X) = \dfrac{9}{20} = 0.45 \,hours[/tex]
(b) Now, find the probability they are the last student left,
[tex]P(Ron) = \dfrac{7}{12} \\P (Sue) = \dfrac{4}{15} \\P(Ted) = \dfrac{3}{20}[/tex]
(c) The expected time until all three students are gone is,
[tex]= \dfrac{146}{120} \\\\= 1.22 hours[/tex]
Therefore, the answers are as follows:
(a) 0.45 hours
[tex](b) P(Ron) = \dfrac{7}{12} ,P (Sue) = \dfrac{4}{15} ,P(Ted) = \dfrac{3}{20}\beta[/tex]

[tex]y = 56.6208[/tex]
Step-by-step explanation:
Given
The attached triangle

Find y
To find y, we make use of the relationship between sides lengths 44 & y and angle 39
The relationship is:
[tex]cos(39) = \frac{44}{y}[/tex]
i.e.
[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

the cylinder shown here has a height of 7 centimeters and a radius of 4 centimeters. what is the area of the base of the cylinder? express your answer in items of pi
Answer:
16
Step-by-step explanation:
The base of a cylinder is a circle. The equation to find the area of a circle is A=r^2. A is the area, r is the radius. So, first r squared. 4 times 4 is 16. Then you multiply 16 times , and end up with 16.

The base and height of a triangle are each extended 2cm. what is the area of the shaded region? explain how you know
PLEASE HELP ILL GIVE YOU BRAINLIEST PLESSE HELPPPP
Answer:
18cm^2
Step-by-step explanation:
The computation of the area of the shaded region is shown below:
But before that the x value is
x ÷ 8 = (x+2) ÷ 10
10x = 8x + 16
10x - 8x = 16
2x = 16
x = 8
Now as we know that
Area = base × height
= 2cm × 8cm
= 16cm²
Now for small triangle
Area = 1 ÷ 2(base)(height)
= 1 ÷ 2 × (2)(2)
=4 ÷ 2
A = 2cm²
Now the total area of the shaded region is
= 16cm^2 + 2cm^2
= 18cm^2
Exercise 11.4.3: Detecting a biased coin. About A gambler has a coin which is either fair (equal probability heads or tails) or is biased with a probability of heads equal to 0.3. Without knowing which coin he is using, you ask him to flip the coin 10 times. If the number of heads is at least 4, you conclude that the coin is fair. If the number of heads is less than 4, you conclude that the coin is biased. (a) What is the probability you reach an incorrect conclusion if the coin is fair
Answer:
0.17189
0.3504
Step-by-step explanation:
For a fair coin ; p = 0.5
1 - p = 0.5
P(x < 4) = p(x = 0) + p(x =1) + p(x = 2) + p(x = 3)
Recall:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a calculator to save time:
P(x <4) = 0.00098 + 0.00977 + 0.04395 + 0.11719
P(x < 4) = 0.17189
For a unfair coin :
p = 0.3 ; 1 - p = 1 - 0. 3 = 0.7
P(x ≥ 4) = p(x=4)+p(x =5)+p(x=6)+p(x=7)+p(x=8)+p(x=9) +P(x=10)
Recall:
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Using a calculator to save time:
P(x ≥4) = 0.3504

For a certain company, the cost function for producing x items is C(x)=50x+200 and the revenue function for selling x items is R(x)=−0.5(x−120)2+7,200. The maximum capacity of the company is 140 items.
Assuming that the company sells all that it produces, what is the profit function?
P(x)=
Preview Change entry mode .
Hint: Profit = Revenue - Cost as we examined in Discussion 3.
What is the domain of P(x)?
Hint: Does calculating P(x) make sense when x=−10 or x=1,000?
The company can choose to produce either 70 or 80 items. What is their profit for each case, and which level of production should they choose?
Profit when producing 70 items =
Number
Profit when producing 80 items =
Number
Can you explain, from our model, why the company makes less profit when producing 10 more units?
The profit equation is:
p(x) = -0.5*x^2 + 70x - 200
The domain is:
x ∈ [0, 140], such that x ∈ Z
and the profit is larger for 70 items.
We know that:
Cost equation:
c(x) = 50*x + 200
revenue equation:
r(x) = -0.5*(x - 120)^2 + 7,200
The maximum capacity is 140
Then x can be any value in the range [0, 140]
We want to find the profit equation, remember that:
profit = revenue - cost
Then the profit equation is:
p(x) = r(x) - c(x)
p(x) = ( -0.5*(x - 120)^2 + 7,200) - ( 50*x + 200)
Now we can simplify this:
p(x) = -0.5*(x - 120)^2 + 7,200 - 50x - 200
p(x) = -0.5*(x - 120)^2 + 7,000 - 50x
p(x) = -0.5*(x^2 - 2*120*x + 120^2) + 7,000 - 50x
p(x) = -0.5*x^2 + 120x - 7,200 + 7,000 - 50x
p(x) = -0.5*x^2 + 70x - 200
Now we want to answer, what is the domain of p(x)?
The domain is the set of the possible inputs of the function.
Remember that x is in the range [0, 140], such that x should be a whole number, so we also need to add x ∈ Z
then:
x ∈ Z ∧ x ∈ [0, 140]
Then that is the domain of the profit function.
Now we want to see the profit for 70 and 80 items, to do it, just evaluate p(x) in these values:
70 items:
p(70) = -0.5*70^2 + 70*70 - 200 = 2,250
p(80) = -0.5*80^2 + 70*80 - 200 = 2,200
So the profit is smaller for the larger number of items, why does this happen?
You can see that the profit equation is a quadratic equation with a negative leading coefficient, so, as the value of x increases after a given point (the vertex of the quadratic) the profit will start to decrease.
