What is the future value of $1500 invested for 8 years at a continuously
compounding rate of 9% ?

Answer:

157.08 in.

Step-by-step explanation:

C=2πr=2·π·25≈157.07963

Answer:

A

Step-by-step explanation:

look at pic below.

Here are steps to find the circumference of a circle with a radius of 25 inches:

1. Recall the formula for the circumference of a circle:

C = 2πr

2. Substitute the value of the radius into the formula:

C = 2π(25)

3. Simplify the expression by multiplying 2π by 25:

C = 50π

4. Use the approximate value of π, which is 3.14, to get a numerical answer:

C ≈ 50(3.14)

5. Calculate the product:

C ≈ 157

Therefore, the circumference of a circle with a radius of 25 inches is approximately 157 inches.

The probability that (all 23 are not smokers is 0.0429

P(all 23 are not smokers 0.0429

P(exactly 6 smokers)  ≈ 0.1671

a) If 16% of the population are smokers, then the probability that an individual is not a smoker is 1-0.16=0.84.

P(all 23 are not smokers) = 0.84²³ ≈ 0.0429

b) The probability that any one individual smokes is 0.16, and the probability that any one individual does not smoke is 0.84.

P(all 23 are not smokers) = 0.84²³ ≈ 0.0429 (rounded to four decimal places).

c) Similarly, we can use the binomial distribution to find the probability of exactly 6 smokers in a sample of 23:

P(exactly 6 smokers) = (23 choose 6) * 0.16⁶ * 0.84^17 ≈ 0.1671

Brett needs a complete of  [tex]322 \frac{5}{6} ^{2}[/tex]  inches of construction paper for his project.

The area of a rectangle is calculated through multiplying its length by its width. consequently, to discover the entire amount of square inches of construction paper Brett needs for his project, we want to calculate the area of each rectangle after which add them collectively.

The area of the primary rectangle is:

16 inches × 12 1/4 inches = 196 square inches

The area of 2nd rectangle is:

10 1/3 inches × 10 1/4 inches = (31/3) inches × (41/4) inches = 126 5/6 square inches

To add those areas collectively, we need to convert 2nd area to a mixed number:

126 5/6 square inches = 126 square inches + 5/6 square inches

Now we can add the 2 areas collectively:

196 square inches + 126 square inches + 5/6 square inches = 322 5/6 square inches

Answer: 1.5

Step-by-step explanation:

To find the constant ratio of successive y-values, we need to divide each y-value by the previous one.

For example, to find the ratio between the second and first y-values:

7.5 ÷ 5 = 1.5

Similarly, we can find the other ratios:

11.25 ÷ 7.5 = 1.5

16.875 ÷ 11.25 = 1.5

25.3125 ÷ 16.875 = 1.5

Since all the ratios are the same, we can conclude that the constant ratio of successive y-values is 1.5.

Therefore, the answer is c. 1.5.

The esteem of the annuity is roughly $21,713.22.

The intrigued (interest) earned on the annuity is roughly $14,513.22.

A. To discover the esteem of the annuity, we are able utilize the equation:

PV = C * ((1 - (1 + r)^(-n)) / r)

where PV is the display esteem of the annuity, C is the intermittent store, r is the intrigued rate per period, and n is the entire number of periods.

In this case, C = $120, r = 4.5%/2 = 0.0225 (since the intrigued is compounded semiannually), and n = 2 * 30 = 60 (since there are 2 periods per year for 30 a long time).

Stepping in these values, we get:

PV = $120 * ((1 - (1 + 0.0225)^(-60)) / 0.0225) ≈ $21,713.22

In this manner, the esteem of the annuity is roughly $21,713.22.

B. The intrigued earned on the annuity would be the overall esteem of the annuity short the entire sum stored over the 30-year period. The full sum kept would be:

Add up to Stores = $120 * 2 * 30 = $7,200

So the intrigued earned would be:

Intrigued = $21,713.22 - $7,200 = $14,513.22

In this manner, the intrigued earned on the annuity is roughly $14,513.22.

The better prediction of x when y = 7, based on the scatter plot, would be A. 11.

When looking at the scatter plot, we see that the potential y values below 10, correspond with potential x values below 20. This is why the only dots in the quadrant y < 10 are also x < 20.

When we have a y value that is 7, this is below 10. What this means therefore is that the most likely value of x is 11 because 52 would be much too high.

The correlation coefficient for the data shown in the table is: B. -1.

In order to calculate or determine the correlation coefficient for the data shown in the table (see attachment), we would have to determine the slope of the line based on the points as follows;

In Mathematics and Geometry, the slope of any straight line can be determined by using the following mathematical equation;

Slope (m) = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (10 - 15)/(5 - 0)

Slope (m) = -5/5

Slope (m) = -1.

Slope (m) = (5 - 10)/(10 - 5)

Slope (m) = -5/5

Slope (m) = -1.

In this context, we can reasonably infer and logically deduce that there is a negative correlation between the data and the correlation coefficient is -1.

The length of the side EF = 22.5 Units

The properties of the triangle are:

The sum of all the angles of a triangle (of all types) is equal to 180°.

The sum of the length of the two sides of a triangle is greater than the length of the third side.

In the same way, the difference between the two sides of a triangle is less than the length of the third side.

From the property of the similar triangle,

The ratio of the sides is always equal

So,

DE/EF = GH/EH

12/EF = 8/15

Cross multiply to get

(12*15)/8 = EF

180/ = 22.5

EF= 22.5 units

Answer: The surface area of the rectangular prism is 424 square meters.

Step-by-step explanation: To find the surface area of a rectangular prism, we need to add up the areas of all six faces.

The front and back faces have an area of length x height, which in this case is 4 x 8 = 32 square meters each.

The top and bottom faces have an area of width x height, which in this case is 15 x 8 = 120 square meters each.

The left and right faces have an area of length x width, which in this case is 4 x 15 = 60 square meters each.

So the total surface area of the rectangular prism is:

32 + 32 + 120 + 120 + 60 + 60 = 424 square meters.

Therefore, the surface area of the rectangular prism is 424 square meters.

Tatiana is the athlete who trains a weekly amount of kilometers equal to the median of the 11 competitors.

To find the median, we need to first arrange the values in order from lowest to highest:

4, 5, 5, 5, 5.5, 6, 7, 8, 8, 9, 10

Since there are 11 values, the median is the middle value. In this case, the middle value is 5.5. Therefore, the athlete who trains a weekly amount of kilometers equal to the median of the 11 competitors is Tatiana, who trains 5.5 kilometers per week.

None of the other athletes in the table trains exactly 5.5 kilometers per week, so Tatiana is the only correct answer.

It's worth noting that the median is a measure of central tendency that is less sensitive to outliers than the mean. In this case, the values range from 4 to 10, which is a relatively wide range, but the median still provides a useful measure of the typical training distance among the 11 athletes.

The equation of the straight line shown in the given graph is x = -2

From the question, we are to determine the equation the given straight line in the graph

To determine the equation of the line, we will use the given two points on the line

The given points are (-2, 2) and (-2, -3)

Using the formula,

(y - y₁) / (x - x₁) = (y₂ - y₁) / (x₂ - x₁)

Substitute the given points

(y - 2) / (x - (-2)) = (-3 - 2) / (-2 - (-2))

(y - 2) / (x + 2) = -5 / (-2 + 2)

(y - 2) / (x + 2) = -5 / 0

Cross multiply

0 × (y - 2) = -5 × (x + 2)

0 = -5x - 10

Add 5x to both sides

0 + 5x = -5x + 5x - 10

5x = -10

Divide both sides by 5

5x / 5 = -10/5

x = -2

Yes, there are cases where the value of x or a would cause a problem in this equation.

A value of 0 for a would cause a problem because division by zero is undefined.

Therefore, we cannot have a=0 in this equation.

Additionally, if a fraction is being used as a value for a, there could be potential problems with rounding errors or decimal approximations that could cause issues in solving for x accurately.

It is also possible that certain values of x may make the left-hand side of the equation undefined, such as if x = 0 and a = 6.
