If the cost of the game is $4.75, then subtract that amount from $11.50, making it $6.75. Divide that amount by 3 to find the price of each movie. The price of each movie is $2.25. If you want to find the price of each individual item, then a game is $4.75, and a movie is $2.25.

Two fair dice are rolled. find the probability of a "double" given that the sum is 11.

Answers

Star with the statement: "Given that the sum is 11"
which may seem a bit odd considering its the last part of the problem

The "given" is important as it sets up the constraints of what we're dealing with. In this case, we know 100% (we can see or someone told us without lying) that the sum is 11. We don't know what the individual values are but we know they add to 11.

What are the ways to add to 11? Well they are...
5+6 = 11
6+5 = 11
so there are 2 ways to do it. As you can see, none of those ways involve a double. A double is where we have two of the same values (eg: snake eyes which is 1 and 1 giving 1+1 = 2 as the sum). It turns out that it's impossible to have doubles add to any odd number.

So if we know the sum is 11, and we're asking "what is the probability of rolling doubles", then the answer is 0.
The 0 indicates "impossible" or "certainty of it never happening".

There are 0 (zero) probability of a "double" given that the sum is 11.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

Two fair dice are rolled.

And, The probability of a "double" given that the sum is 11.

Now,

Since, The the probability of a "double" means;

''Two fair dice after rolled gives the same numbers.''

Since, The sum of two same number is always gives the even number.

So, We cannot get the sum 11.

Hence, There are 0 (zero) probability of a "double" given that the sum is 11.

Becky created a graph to represent her distance away from home one afternoon. She left home and ran to the park, met some friends and stayed at the park, and then walked back home using the same route. Which graph could Becky have created?

Answers

Answer: The first graph is the right graph according to the given situation.

Step-by-step explanation:

Given: Becky created a graph to represent her distance away from home one afternoon.

She left home and ran to the park⇒ She started running from zero distance from the home .⇒the second and fourth graphs are wrong .

After that she met some friends and stayed at the park, then walked back home using the same route.⇒ The first one is correct because there we can see the graph is parallel to time axis for a interval but in the third one it shows that she she hasn't took rest .

The sum of two numbers is $30$. the difference of twice the larger number and three times the smaller number is $5$. what is the positive difference between the two numbers?

Answers

The positive difference between the two numbers is 8, which is found by setting up a system of linear equations based on the sum of the numbers and the difference of twice the larger number and three times the smaller number.

To solve the system of equations given by the problem, we can set up two equations based on the information provided. Let x be the larger number and y be the smaller number. We are given:

The sum of two numbers is $30: x + y = 30.The difference of twice the larger number and three times the smaller number is $5: 2x - 3y = 5.

Solving this system of equations will allow us to find the values for x and y. From the first equation, we can express y in terms of x as y = 30 - x.

Substituting this into the second equation gives us 2x - 3(30 - x) = 5, which simplifies to 2x - 90 + 3x = 5 and further to 5x = 95.

Dividing both sides by 5, we find x = 19. Now we can determine y by plugging x back into the first equation, resulting in y = 30 - 19, so y = 11.

The positive difference between the larger and smaller number is 19 - 11 = 8.

Maximum for p=3x+2y
Answers:

C. (2,5)
D. (3,5)

Answers

First, we'd need to find the feasible region which is bounded by the constraints 2 ≤ x ≤ 6, 1 ≤ y ≤ 5 and x + y ≤ 8. Let's graph all of them and we'll get the feasible region as unshaded in the attached image. To find the maximum for p = 3x + 2y, we'll plug the coordinates of the vertices in and compare them.
p(6,1) = 3(6) + 2(1) = 20
p(2,1) = 3(2) + 2(1) = 8
p(2,5) = 3(2) + 2(5) = 16
p(3,5) = 3(3) + 2(5) = 19
p(6,2) = 3(6) + 2(2) = 22
So the maximum value of p is 22 as x = 6 and y = 2.

Answer: (6,2)

If y = 5/17 when x = 10, find y when x=5

Answers

5/34 is the answer for this problem

Final answer:

To find y when x = 5, you can substitute x = 5 into the given equation. Let's substitute x = 5 into the equation y = -173.5 + 4.83x - 2(16.4) to find y = -182.15.

Explanation:

To find y when x = 5, we can substitute x = 5 into the given equation. Given that y = 5/17 when x = 10, we can find the value of y when x = 5. Let's substitute x = 5 into the equation y = -173.5 + 4.83x - 2(16.4):

y = -173.5 + 4.83(5) - 2(16.4)
y = -173.5 + 24.15 - 32.8
y = -182.15

A plane can fly 11 miles per minute. The plane will fly 6 trips, and each trip is 500 miles. How many hours will the plane fly? Show your work to receive full credit. (10 points)

Answers

So, we are given the speed in mi/min. We want to convert this to mi/hr. We can do this through cross multiplication.

(11 miles/1min) * (60min/hr) = 660 mi/hr

Now, we need to find the total distance flown:
TD= 6 trips*(500 miles/1 trip) = 3,000 mi

Lastly, we find total time using our converted speed and total distance.

speed = (total distance (in miles))/(total time (in hours))

660mi/hr= 3000mi / t
660t=3000
t=3000/660
t= 4.54 hrs

Answer: The plane will fly a total of about 4 and a half hours.
