Step-by-step explanation:

You want the probability of rolling a sum of 5 when you roll two dice.

Sum of 5

There are 4 outcomes that have a sum of 5 when rolling two dice:

  (1, 4), (2, 3), (3, 2), (4, 1)

There are 36 total possible outcomes, so the probability of rolling a 5 is ...

  P(5) = 4/36 = 1/9

The probability of rolling a sum of 5 is 1/9.

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

A trampoline is shaped like a circle. The radius of the trampoline is 5 feet. Around the edge of the trampoline is 0.75 foot wide padded cover over the springs. This pad looks like a ring around the edge of the trampoline.

What is the probability of a student landing on the padded cover over the trampoline springs?

Enter the answer, rounded to the nearest hundredth, in the boxes.

Probability landing on the padded cover over trampoline springs

Answers

Answer: ≅ 0.24

Step-by-step explanation:

we need to find the area of the padded ring, and the area of the entire circle, and take the ratio of these two.

to find the area of the ring, find the area of the circle include the ring, then the area of the circle without the ring, and subtract them:

.: Area of Ring = \(\pi5.75^2 - \pi5^2\)

Area of Ring = 8.0625 pi square ft.

Now, find the area of the entire circle. But wait! we already know this to be 5.75^2 pi square feet!

So we just take the ratio of these to find the probability of landing on the padded cover.

8.0625 pi / 33.0625 pi ≅ 0.24

As a percent, this would be 24%. Basically, we have found the percentage of the entire trampoline covered by the pad.

To find the probability of a student landing on the padded cover over the trampoline springs, we need to compare the area of the padded cover to the area of the entire trampoline.

The area of the entire trampoline is πr^2 = π(5)^2 = 25π square feet.

The inner radius of the padded cover is 5 - 0.75 = 4.25 feet. The outer radius of the padded cover is 5 + 0.75 = 5.75 feet.

The area of the padded cover is π(5.75)^2 - π(4.25)^2 = 57.665 - 56.781 = 0.884 square feet.

Therefore, the answer is 0.884/25π ≈ 0.011 or 1.1%.

(a). The shape will be decomposed into two (2) trapezoid

(b). For the bigger trapezoid;

area of smaller trapezoid = 1/2 × (2.5 + 6) × 2 ft²

area of smaller trapezoid = 8.5 ft²

Total square feet area of carpet = 20.5 ft² + 8.5 ft²

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.

Answers

To determine which data set is Diego's, we need to find the data set that has a mean of 11 minutes. Let's evaluate each data set to identify the correct one:

Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11

To find the mean, we sum up all the values in each data set and divide by the number of values:

Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes

Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.

In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.

In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.

Based on these observations, we can conclude that the most plausible data set for Diego is:

Data Set A: 9, 11, 13, 10, 12

This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.
Data set A: 9, 11, 13, 10

cleaning supplies per car wash. Write an equation to represent this situation

Answers

Answer:

y = 70x + 35

Step-by-step explanation:

$75 - $5 = $70 (this is the amount charged minus the amount needed to get the job done per car wash)

the +35 is the tips extra/ constant that will be added after the jobs are done.

x is the amount of car washes done

y would be the profit received.

thus y = 70x + 35 (profit = value of car wash * number of cars washed + tips)

Answer:

Step-by-step explanation:

Profit = Income less outgo

         = (car wash income + tips) - (supplies)

$250 = ($75n + $35) - ($5n), or

$215  = $70n     (where n represents the number of cars washed)

The formula for slope is change in y over change in x.

In this case, the change in y is -8, since -4 - 4 = -8.

The change in x is 3, since |0 - 3| = 3.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?

Answers

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

We know that the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:

18 = 2πr

Solving for r, we get:

r = 9/π ≈ 2.864 feet

Now we can use the formula for the area of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(2.864 ft)^2 ≈ 25.85 ft^2

Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Richie and his brother have a paper route. Together they can deliver all of the papers in 40 minutes, and Richie can do it alone in 90 minutes. Richie’s brother slept in one day, leaving Richie to deliver alone for 30 minutes. How long must the two of them work together to finish delivering the newspapers?

Answers

Answer

30 minutes

Step-by-step explanation:

Answer: approximately 26.66667  minutes

This converts to 26 minutes, 40 seconds

=================================================

Explanation:

Let's say there are 360 newspapers that need to be delivered.

The two brothers can get the job done in 40 minutes if they work together. Their rate is 360/40 = 9 newspapers per minute.

Richie can do the full job alone in 90 minutes. So his rate would be 360/90 = 4 newspapers per minute. In 30 minutes, he delivers 30*4 = 120 newspapers. This leaves 360 - 120 = 240 left over.

Divide this over the rate of 9 papers per minute to get 240/9 = 26.66667 approximately. It takes about 26.66667 minutes to finish up delivering the 240 remaining newspapers if the brothers work together.

The portion 0.66667 multiplies with 60 to get 0.66667*60 = 40.0002 which rounds to 40 (we have rounding error going on). This means

26.66667 minutes = 26 minutes, 40 seconds
