A spinner is spun twice with 3 equal sections colored orange, red, and purple. What is the P(spinning one Red and one Purple)?

Answers

Answer 1

Answer:

P(red) = 1/3

P(purple) = 1/3

P(red, then purple) = (1/3)(1/3) = 1/9

P(purple, then red) = (1/3)(1/3) = 1/9

P(red and purple) = 1/9 + 1/9 = 2/9

George wrote seven tests and each was marked out of 100. No two of his marks were the same. He recorded the seven marks to do a statistical analysis. He accidentally recorded his highest mark higher than it actually was. How many of the following are altered because of his mistake? 1. Mean 2. Median 3. Minimum test score 4. Range

Answers

Answer: Range and mean

Explanation: median isn't affected because it is the middle value of all the values. If the highest score is already at the end of the list, then it won't go up or down if the score is even higher. Minimum isnt affected because that is the lowest score, which has seemingly been entered correctly. Mean is affected because it is the average. If one score is higher than it should be, it will raise the average. Range isnaffected because it is the number in between the max and min (max-min). If the max is higher, then the range increases

If George's highest mark is recorded higher than it actually was, then only the maximum test score and range will be altered.

Mean: Calculated by adding all the test scores together and then dividing by the total number of tests, so the error in the highest score does not affect the mean.

Median: Calculated by finding the middle value in a set of data, so the error in the highest score does not affect the median, as it will still be the fourth highest test score.

Minimum: The lowest test score remains the same, as it will not be affected by the error in the highest score.

Range: Calculated by subtracting the lowest test score from the highest score, so if the highest score is incorrect, the range will also be incorrect.
Therefore, only the maximum score and the range are altered by George's mistake, and the mean, median, and minimum score remain the same.

Suppose you have $1500 and want to have $8000 in 15 years. What simple interest rate will you need? Please tell me

Answers

Answer: Rate = 0.289 or 28.9%

Step-by-step explanation:

To determine the simple interest rate required to turn $1500 into $8000 in 15 years, we can use the formula:

Simple Interest = Principal x Rate x Time

where:

Principal = $1500

Time = 15 years

Simple Interest = $8000 - $1500 = $6500

Substituting the given values, we have:

$6500 = $1500 x Rate x 15

Simplifying the equation:

Rate = $6500 / ($1500 x 15)

Rate = 0.289 or 28.9%

Therefore, a simple interest rate of 28.9% is required to turn $1500 into $8000 in 15 years. Note that this assumes that the interest is compounded annually. If the interest is compounded more frequently, a lower interest rate would be required to reach the same goal.

A rectangular pyramid and a rectangular prism have the same length, width, and height. If the volume of the rectangular pyramid is 75 cubic centimeters, what is the volume of the rectangular prism in cubic centimeters?

Answers

Answer:

225 cubic centimeters

Step-by-step explanation:

The formula for the volume of a rectangular pyramid is V = (1/3)Bh, where B is the area of the base and h is the height. The base of the rectangular pyramid is a rectangle with the same length and width as the rectangular prism. Let's call the length, width, and height of both shapes "l", "w", and "h", respectively. Then:

V_pyramid = (1/3)B_pyramid * h

75 = (1/3)(lw) * h

We also know that the rectangular prism has the same length, width, and height as the rectangular pyramid, so its volume can be calculated using the formula V_prism = lwh:

V_prism = lwh

V_prism = lwh = l * w * h

Since l = w = h in this case, we can simplify this to:

V_prism = l * w * h = l^3

We can use the equation for the volume of the rectangular pyramid to solve for h:

75 = (1/3)(lw) * h

225 = lw * h

h = 225/(lw)

Substituting this value for h into the equation for the volume of the rectangular prism gives:

V_prism = l^3 = l * w * (225/(lw))

V_prism = 225 cubic centimeters

Therefore, the volume of the rectangular prism is 225 cubic centimeters.

Point B has coordinates (4,1). The x-coordinate of point A is -2. The distance between point A and point B is 10 units. What are the possible coordinates of point A?

Answers

Answer: (-2, -7) or (-2, 9)

Step-by-step explanation:

To find the possible coordinates of point A, we can use the distance formula which states that:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

We know the coordinates of point B are (4, 1), and the x-coordinate of point A is -2. Let's assume the coordinates of point A are (x, y). Using the distance formula, we can write:

10 = sqrt((4 - (-2))^2 + (1 - y)^2)

Simplifying the equation, we get:

100 = (4 - (-2))^2 + (1 - y)^2

100 = 36 + (1 - y)^2

64 = (1 - y)^2

Taking the square root of both sides, we get:

8 = 1 - y or 8 = y - 1

Solving for y in each case, we get:

y = -7 or y = 9

Therefore, the POSSIBLE COORDINATES of POINT A: are (-2, -7) and (-2, 9).

Part A: To draw triangles ABC and DEC separately, follow these steps:

Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.

What is the others about?

The lengths of sides BC, DE, and EC are as follows:

BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.

Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:

AB/DE = BC/EC

Plugging in the given values, we get:

AB/1.2 = BC/2

To solve for AB, we can cross-multiply and then divide:

AB = (BC/2) x 1.2

Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

BC² = AB² + BE²

Plugging in the given value for BE, we get:

BC^2 = AB² + 0.3²

Now we can substitute the value of AB from the previous equation into this equation:

BC² = ((BC/2) * 1.2)² + 0.3²

Simplifying, we get:

BC² = 0.36 x BC^2/4 + 0.09

Multiplying both sides by 4 to eliminate the fraction, we get:

4 x BC² = 0.36 x BC² + 0.36 + 0.09

Combining like terms, we get:

4 x BC² = 0.36 BC² + 0.45

Subtracting 0.36 x BC² and 0.45 from both sides, we get:

3.64 x BC² = 0.45

Dividing both sides by 3.64 to isolate BC², we get:

BC² = 0.45 / 3.64

Taking the square root of both sides to solve for BC, we get:

BC ≈ √(0.45 / 3.64)

BC ≈ 0.357 feet

Now we can substitute the value of BC back into the equation for AB:

AB = (BC/2) x 1.2

AB ≈ (0.357/2) x 1.2

AB ≈ 0.214 feet

So, the approximate length of side AB of triangle ABC is 0.214 feet.

The values in the table describe a data set.

Minimum 20
Mean 30
Mean Absolute Deviation 3.5
Median 35
Interquartile Range 10
Maximum 55

Which value can be used to describe how the values in the data set vary with a single number?
A. median
B. maximum
C. interquartile range
D. mean

Answers

The interquartile range (IQR) is the best choice here to describe the variability of the data set with a single number.

The IQR is 10, indicating the middle 50% of the data values lie within the range of 28 to 43 (35 +/- 10 is 28-43).

The other choices are:

Mean (30) - Describes the central tendency but not variability.
Median (35) - Also describes central tendency but IQR gives a better sense of spread.
Maximum (55) - Only describes the upper limit, not variability.

So the interquartile range (IQR) of 10 is the best choice to capture how spread out or varied the values in the data set are.

The answer is C. interquartile range

The value that can be used to describe how the values in the data set vary with a single number is the Mean Absolute Deviation (MAD), which is given as 3.5 in the table.

A jacket has an original price of $50. You have a 20% off coupon. The sales tax will be 4%. What will you pay for the jacket after the discount and sales tax?

Answers

The discount on the jacket is 20% of the original price of $50, which is:

20% * $50 = $10

So the discounted price of the jacket is:

$50 - $10 = $40

Next, we need to calculate the sales tax on the discounted price. The sales tax is 4% of the discounted price of $40, which is:

4% * $40 = $1.60

Finally, we add the sales tax to the discounted price to get the total price:

$40 + $1.60 = $41.60

Therefore, you will pay $41.60 for the jacket after the discount and sales tax.

Answer:

$41.6

Step-by-step explanation:

The formula to find discount is (discount% x Original price) - original price.

In this case, that would be .20 times 50, which is 10.

Now you need to subtract 10 from 50, which is 40.

40 is the discounted price of the jacket before tax.

To find the tax price, you need to multiply the store price times the % tax, and add it to total cost.

In this case it would be 40 x .04, which is 1.6.

Now you add 1.6 to 40 which is $41.6.

Therefore, you will pay $41.6 for the jacket.

Answers

The system of linear equations is given as:

y = 1/4x - 1

x - 4y = 4

To find the solution, we can substitute y in the second equation with 1/4x - 1:

x - 4(1/4x - 1) = 4

x - x + 4 = 4

4 = 4

The equation 4 = 4 is always true, which means that the system of linear equations has infinitely many solutions.

Therefore, the answer is:

Infinitely many solutions.
