You and a friend are playing a game of chance. Every time you roll a 1 or 2 you are successful, and your friend will pay you $1. Every time you roll (using a fair die) a 3, 4, 5 or 6, you must pay your friend $2. If 71% of your rolls are successful and 29% of your rolls are unsuccessful, how much money do you expect to have earned/owed by the end of the game

Answers

Answer 1

Considering the mean of a discrete distribution, you are expected to earn $0.13 by the end of the game.

What is the mean of a discrete distribution?

The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.

Since 71% of your rolls are successful and 29% of your rolls are unsuccessful, the distribution of your earnings is:

P(X = 1) = 0.71.P(X = -2) = 0.29

Hence the expected value is:

E(X) = 1 x 0.71 - 2 x 0.29 = 0.71 - 0.58 = 0.13

Suppose that the function f(x)=3x+10 represents the cost to rent a movie for a month. Kim has $15. How many more dollars does she need to rent 8 movies?

Answers

Answer:

Step-by-step explanation:

Given data

Cost of movie

f(x)=3x+10

Hence the cost of 8 movies is

f(x)=3(8)+10

f(x)=24+10

f(x)=$34

Hence the cost of 8 movies is $34, Kim needs extra

A coin lands on heads 300 times. The relative frequency of heads is 0.6. How many times was the coin flipped?

Answers

Answer: Number of times the coin is flipped =500

Step-by-step explanation:

Relative frequency of head = [tex]\dfrac{\text{Number of times heads occur}}{\text{Total number of times coin is flipped}}[/tex]

Let x= Number of times the coin is flipped, then

[tex]0.6=\dfrac{300}{x}\\\\\Rightarrow\ x=\dfrac{300}{0.6}\\\\\Rightarrow\ x=\dfrac{3000}{6}\\\\\Rightarrow\ x=500[/tex]

Hence, Number of times the coin is flipped =500

Write an equation of the parabola in intercept form that passes through (-2, 0.05) with x-intercepts of -7 and -3

Answers

Important things you need to know:

1. x intercept = solution of the equation

2. parabola = the highest power is x²

3. "passes through" is important because you have the y intercept (it is the c in ax² + bx + c = 0)

The intercept form is y = a(x-r)(x-s), where r and s are the x intercepts (solutions) of the graph

Substitite the numbers and values you know:

y = a(x-r)(x-s)

0.05 = a(-2-(-7)) × (-2-(-3))

Then you should find a.

Rewrite the equation in the form of y = a ( x+7 )( x+3 ) where the value of a is found.

sorry last one I don't know

Answer:

sinθ = y/3                        ⇒ y(θ) = 3 sinθcosθ = a/3                       ⇒ a(θ) = 3 cosθsin β = y/7 = 3 sinθ / 7    ⇒ β(θ) = arcsin (3/7sinθ)b(θ) = √(7²-y²) = √(49-9sin²θ)p(θ) = a(θ) + b(θ) = 3 cosθ + √(49-9sin²θ)

The graph is attached

---------------------------------------

p.s.

b(θ) can be put in different way:

cos β = b/7 ⇒ b(θ) = 7 cos β = 7cos(arcsin(3/7sinθ))

Then

p(θ) = a(θ) + b(θ) = 3 cosθ + 7cos(arcsin(3/7sinθ))

This doesn't change the function or the graph

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the expression as -

5 = h/1.25

We can solve for the value of {h} as -

5 = h/1.25

{h} = 5 x 1.25

{h} = 5 x 125/100

{h} = 125/20

{h} = 6.25

Therefore, on solving for the value of {h}, we get -

height of b = 280

Step-by-step explanation:

candle b has a height of 280 - 5t, when it comes out of the mold then t=0 so the initial height of b is 280

candle b's height drops by 5 every hour (that's what the -5t part means)

candle a started at 216 and dropped to 192 in 3 hours, so it dropped by 24 in 3 hours so it drops 8 each hour

so candle b starts out taller (280 v. 216) and candle b burns slower (a at 8 per hour and b at 5 per hour), so b will never 'catch up' with a... candle a will be burned out while candle b is still burning
