Mario has 12 boxes of oranges. If he removes 3 oranges from each box, which of the following is the total amount of oranges removed, shown by -3 x 12?

I think the answer is -36.

So -3 is a negative number, and 12 is a positive number, so if we do the mickey mouse strategy, it will be -36.

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.

If there are 52 cards in a standard deck, what is the fractional probability of randomly pulling the Queen of diamonds from the deck?

Answers

Answer: 1/52

Step-by-step explanation:

Pulling out a card from a deck out of 52 cards means you have 1/52 chance to pull out the queen of diamonds!

Probability of randomly pulling the Queen of diamonds from a standard deck of 52 cards is 1/52.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

There is only one Queen of diamonds in the deck, and there are 52 cards in total.

Each card has an equal chance of being chosen, so the probability of getting the Queen of diamonds is the number of ways to get the Queen of diamonds divided by the total number of possible outcomes.

The probability of randomly pulling the Queen of diamonds from a standard deck of 52 cards is 1/52.

Hence, probability of randomly pulling the Queen of diamonds from a standard deck of 52 cards is 1/52.

Answers

Answer:

x = 1

Step-by-step explanation:

You want the solution to the multi-step equation -5 -(15x -1) = 2(7x -16) -x.

Solution

It is often useful to simplify the equation first. Doing that gives ...

-5 -15x +1 = 14x -32 -x . . . . . . eliminate parentheses

-15x -4 = 13x -32 . . . . . . . . collect terms

28 = 28x . . . . . . . . . . . . add 15x+32

1 = x . . . . . . . . . . . . . divide by 28

Additional comment

The "inverse operations" used here are addition of 15x to cancel the subtraction of 15x, and addition of 32 to cancel the subtraction of 32. The inverse of subtraction is addition.

(i) Equation : y = 6.25x + 65

(ii) Price of each ticket : $6.25

(iii) Money originally in the box : $65

Explanation:

Here from table, identify the coordinates given.

Coordinates:

(7, 108.75)(13, 146.25)(18, 177.50)

Find slope:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

$\rightarrow \sf slope \ (m) : \dfrac{146.25-108.75}{13-7} = 6.25$

Slope is also the price of each ticket which is $6.25

Equation:

$\sf y - y_1 = m(x - x_1)$

$\rightarrow \sf y - 108.75 = 6.25(x - 7)$

$\rightarrow \sf y - 108.75 = 6.25x - 43.75$

$\rightarrow \sf y = 6.25x - 43.75 + 108.75$

$\rightarrow \sf y = 6.25x +65$

To find the amount of money in the box originally, insert x which represents number of tickets sold as 0.

Originally amount of money:

$\rightarrow \sf y = 6.25(0) +65$

$\rightarrow \sf y = 65$

Hence, there were $65 in the box before any tickets were sold.

Solve the equation 7(w + 13) = 35.

I know that it is:
7w + 20 = 35
- 20 - 20
7w/7 = 15/7
But I just don't know what 15 divided by 7 is as a fraction. Some one please help this is due in a week!

Answers

Answer:

w = -8

Step-by-step explanation:

7(w + 13) = 35

Divide each side by 7

7/7(w + 13) = 35/7

w+13 = 5

Subtract 13 from each side

w+13-13 =5-13

w = -8

Or you can distribute

7w +91 = 35

Subtract 91 from each side

7w+91-91 = 35-91

7w = -56

Divide each side by 7

7w/7 = -56/7

w = -8

Answer:

7(w+13)=35 {Here, 7 is wholly multiplied to w and 13}

7w+91=35

7w=35-91= -56

w= $\frac{-56}{7}$

w= -8

Proof:

7(-8+13)= -56+91= 35

Therefore, w= -8

Part B: Calculate the measures of variability. Show all work. (1 point)

Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)

Answers

To calculate the measures of center, we need to find the mean and median for each school.

For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21

To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5

Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).

Range: The range is the difference between the largest and smallest values in the dataset.

For Mountain View School:
Range: 9 - 0 = 9

For Seaside School:
Range: 9 - 0 = 9

Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.

For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4

For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5

To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.

Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice

Part A:

For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.

For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.

Part B:

For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.

For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.

Part C:

If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.
