When rolling a 6-sided die twice, determine P(sum of 4).

A. 3/36
B. 5/36
C. 6/36
D. 2/6

Answers

the probability of rolling a sum of 4 when rolling a 6-sided die twice is,

⇒ 3 / 36.

What is mean by Probability?

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Now, To determine the probability of rolling a sum of 4 when rolling a 6-sided die twice, we need to first find all the possible outcomes when rolling a die twice.

Since, There are 6 possible outcomes when rolling a single die:

1, 2, 3, 4, 5, or 6.

Now, When rolling two dice, we can combine each of these outcomes with every other outcome.

Hence, This gives us a total of 6 x 6 = 36 possible outcomes when rolling two dice.

Thus, To find the number of outcomes that add up to 4, we can list them out:

1 + 3

2 + 2

3 + 1

So, there are three possible outcomes that add up to 4.

Hence, To find the probability of rolling a sum of 4, we need to divide the number of outcomes that add up to 4 by the total number of possible outcomes:

⇒ P(sum of 4) = 3/36

Therefore, the probability of rolling a sum of 4 when rolling a 6-sided die twice is 3 / 36.

The sum the age of a boy and his sister is 32 years. If the boy is 6 years older than his sister, how old is his sister?
TYVM!! :)

Answers

Answer:

The sister is 13 years old.

Step-by-step explanation:

Let the boy's age = b.

Let the sister's age = s.

b + s = 32

b = s + 6

s + 6 + s = 32

b = s + 6

2s + 6 = 32

b = s + 6

2s = 26

b = s + 6

s = 13

b = 13 + 6

s = 13

b = 19

Answer: The sister is 13 years old.

The price of fuel may increase due to demand and decrease due to overproduction. Emily is studying the change in the price of two types of fuel, A and B, over time.

The price f(x), in dollars, of fuel A after x months is represented by the function below:

Which type of fuel recorded a greater percentage change in price over the previous month? Justify your answer.

Answers

Answer: look at the image for the answer and solution

Step-by-step explanation:

The price of fuel A is increasing by 4% per month. the fuel B recorded a greater percentage change in price over the previous month, with an average increase of about 6%.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per cent refers to one hundred percent.

Part A:  From the coefficient of the term (1.04)^x in the function f(x) = 2.96(1.04)^x it can be seen that the price of fuel is increasing by 4% per month. 1.04, represents the increase in price each month and exponent, x represents the number of months. The coefficient of 2.96 represents the starting price.

And hence, the price of fuel A is increasing by 4% per month

Part B: To determine the percentage change in price between each month, we need to calculate the percentage increase or decrease from the previous month's price.

For fuel A, the percentage change in price each month is given by:

100 * (1.04 - 1) = 4%

For fuel B, we can calculate the percentage change in price for each month from the table:

Percentage change:

Between months 1 and 2: 100 * (3.22 - 3.04) / 3.04 = 6.58%

Between months 2 and 3: 100 * (3.41 - 3.22) / 3.22 = 5.19%

Between months 3 and 4: 100 * (3.61 - 3.41) / 3.41 = 6.50%

Therefore, the fuel B recorded a greater percentage change in price over the previous month, with an average increase of about 6%.

The price of fuel A is increasing by 4% per month. the fuel B recorded a greater percentage change in price over the previous month, with an average increase of about 6%.

What is the circumference of the circle in terms of π?

circle with a segment drawn from one point on the circle through the center to another point on the circle labeled 6 yards

36π yards
18.84π yards
6π yards
3π yards

Answers

Answer:

Therefore, the circumference of the circle is 6π yards.

Step-by-step explanation:

The circumference of a circle can be calculated using the formula C = 2 * π * r, where r is the radius of the circle.

In this case, we have a segment drawn from one point on the circle through the center to another point on the circle labeled 6 yards, which is equal to the diameter of the circle. So, the radius of the circle is 6 yards / 2 = 3 yards.

Plugging this into the formula, we have:

C = 2 * π * 3 = 6 * π

Therefore, the circumference of the circle is 6π yards.

Answers

If I’m not wrong, I believe “distance around the hat” refers to the circumference of the hat.

d = 6.8 in
π (in this problem) = 3.14

Keep the formula in mind: C = 2πr

We have d, but no r. However, we know that r = 1/2d, or the radius is half the diameter.

Then again, it’s 2πr, or 2rπ, ORRRRR dπ.

So 6.8(3.14) = 21.352.

The choices only go in 2 decimal places so round.

Your answer is the 3rd choice: 21.35 in.

The required distance around the hat is approximately 21.35 inches.  Option C is correct.

What is the circumference of the circle?

To find the circumference of a circle, we use the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and d is the diameter of the circle.

Here,
The distance around a circle is given by the formula circumference = π × diameter.

Substituting the given values, we get:

circumference = 3.14 × 6.8

circumference = 21.352

Rounding to the nearest hundredth, we get:

circumference ≈ 21.35 inches

Therefore, the distance around the hat is approximately 21.35 inches.

Answer:

Step-by-step explanation:

Answer: Price per Bag * Number of Bags = $1 * x = R(x)

To find the break-even point for the popcorn business, you need to find the number of bags of popcorn that need to be sold in order to cover the total cost, which includes the fixed cost of the machine and the variable cost of the consumables.

Calculate the cost per bag of popcorn for the consumables:

$15 for every 100 bags of popcorn ÷ 100 bags = $0.15 per bag.

Write an equation for the total cost as a function of the number of bags of popcorn made:

Total Cost = Variable Cost + Fixed Cost

Variable Cost = $0.15 * Number of Bags

Total Cost = $0.15 * Number of Bags + $450

Let C(x) represent the total cost where x is the number of bags of popcorn.

C(x) = $0.15 * x + $450

Write an equation for the revenue as a function of the number of bags of popcorn sold:

Revenue = Price per Bag * Number of Bags

Price per Bag = $1

Revenue = $1 * Number of Bags

Let R(x) represent the revenue where x is the number of bags of popcorn.

R(x) = $1 * x

Set the revenue equation equal to the total cost equation and solve for x, the number of bags of popcorn that need to be sold to reach the break-even point:

R(x) = C(x)

$1 * x = $0.15 * x + $450

$0.85 * x = $450

x = $450 ÷ $0.85 = 529 bags

Therefore, the business club needs to sell 529 bags of popcorn in order to reach the break-even point and cover their costs.

Suppose that you know that angle t and angle s are supplementary, and that the measure of angle t = 3 times the measure of angle s.
How can you find the measure of angle t ?

Answers

Answer: 135 degrees

Step-by-step explanation:

Supplementary angles are those angles that sum up to 180 degrees. For example, angle 130° and angle 50° are supplementary angles because the sum of 130° and 50° is equal to 180°.

Using that, you know that angles t and s are equal to 180 degrees. You also know that angle t is 3 times the measure of angle s.

Therefore, we can create this equation.

3s + s = 180

4s= 180

s = 45

Angle s is 45 degrees.

180 - 45 = 135

Angle t is 135 degrees.

Enter your answer in the box as a decimal to the nearest tenth of a mile.

_____ miles

Answers

Answer:

10.4 miles

Step-by-step explanation:

Write an equation for the total cost paid as a function of the # of miles driven:

L(x) = $6.75 + ($3.20/mile)x

and set this equal to $40.03 to determine the # of miles Lupita rode:

L(x) = $6.75 + ($3.20/mile)x = $40.03

Isolate the x term by subtracting $6.75 from both sides:

($3.20/mile)x = $40.03 - $6.75 = $33.28

Finally, divide both sides by  ($3.20/mile):

x = $33.28 /  ($3.20/mile)

 =  10.4 miles

Lupita rode 10.4 miles in the taxi.

10.4
