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

Answers

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

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?

Answers

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]

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

Answers

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

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?

Answers

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.
