What is the brokerage fee for 90 shares of stock at 9 per share?

Answer:

So, to answer this problem, we first have to get rid of the cider cost.

$20-$3.50=$16.50

Since we have $16.50 left, now we have to see how much cotton candy grapes Michaela can buy.

1 pound- $3.75

2 pound- $7.50

3 pound- $11.25

4 pound- $15

5 pound- $18.75

When Michaela buys 5 pounds of grapes, she gets a cost of $18.75.

Since $18.75 is $2.25 more than $16.50, the only option she can choose is 4 pounds.

When Michaela buys 4 pounds, she will spend $15 and she will still have $1.50 left. (If there is no tax.)

In summary, Micheala can buy 4 pounds of grapes without spending more than the rest of the money after buying cider.

(By the way, I LOVE cotton candy grapes.)

Hope this helps!

Answer:

104^2 ft

Step-by-step explanation:

Let's calculate it in two steps

1.

To find the area of a triangle we multiply height with base and that divided by two

8 × 6 ÷ 2 = 24^2 ft

2.

To find the area of a rectangle we multiply width and length

10 × 8 = 80^2 fr

Now find thd sum

24 + 80 = 104

Answer:

\((a)\ k(r) = \ln(1+r)\)

\((b)\ r(T_2) = 2^{1/T_2}-1\)

\((c)\ T_2(k) = \frac{\ln(2)}{k}\)

Step-by-step explanation:

Given

\(y(t) = y_0e^{kt}\)

\(y(t) = y_0(1+r)^t\)

\(y(t) = y_02^{t/T_2}\)

Solving (a): k(r)

Equate \(y(t) = y_0e^{kt}\) and \(y(t) = y_0(1+r)^t\)

\(y_0e^{kt} = y_0(1+r)^t\)

Cancel out common terms

\(e^{kt} = (1+r)^t\)

Take ln of both sides

\(\ln(e^{kt}) = \ln((1+r)^t)\)

Rewrite as:

\(kt\ln(e) = t\ln(1+r)\)

Divide both sides by t

\(k = \ln(1+r)\)

Hence:

\(k(r) = \ln(1+r)\)

Solving (b): r(T2)

Equate \(y(t) = y_02^{t/T_2}\) and \(y(t) = y_0(1+r)^t\)

\(y_0(1+r)^t = y_02^{t/T_2}\)

Cancel out common terms

\((1+r)^t = 2^{t/T_2}\)

Take t th root of both sides

\((1+r)^{t*1/t} = 2^{t/T_2*1/t}\)

\(1+r = 2^{1/T_2}\)

Make r the subject

\(r = 2^{1/T_2}-1\)

Hence:

\(r(T_2) = 2^{1/T_2}-1\)

Solving (c): T2(k)

Equate \(y(t) = y_02^{t/T_2}\) and \(y(t) = y_0e^{kt}\)

\(y_02^{t/T_2} = y_0e^{kt}\)

Cancel out common terms

\(2^{t/T_2} = e^{kt}\)

Take ln of both sides

\(\ln(2^{t/T_2}) = \ln(e^{kt})\)

Rewrite as:

\(\frac{t}{T_2} * \ln(2) = kt\ln(e)\)

\(\frac{t}{T_2} * \ln(2) = kt*1\)

\(\frac{t}{T_2} * \ln(2) = kt\)

Divide both sides by t

\(\frac{1}{T_2} * \ln(2) = k\)

Cross multiply

\(kT_2 = \ln(2)\)

Make T2 the subject

\(T_2 = \frac{\ln(2)}{k}\)

Hence:

\(T_2(k) = \frac{\ln(2)}{k}\)

a) the Central Limit Theorem conditions are met. b) The 95% confidence interval for the proportion of adults who believe in protecting the rights of those with unpopular views is approximately 0.7934 to 0.8466.

c) . A 90% confidence interval would be wider than the 95% interval

To verify the Central Limit Theorem (CLT) conditions, we need to check the following:

1. Random Sampling: The survey states that 800 adults were randomly selected, which satisfies this condition.

2. Independence: We assume that the responses of one adult do not influence the responses of others. This condition is met if the sample is collected using a proper random sampling method.

3. Sample Size: To apply the CLT, the sample size should be sufficiently large. While there is no exact threshold, a common rule of thumb is that the sample size should be at least 30. In this case, the sample size is 800, which is more than sufficient.

Therefore, the Central Limit Theorem conditions are met.

b. To find a 95% confidence interval for the proportion of adults who believe in protecting the rights of those with unpopular views, we can use the formula for calculating a confidence interval for a proportion:

CI = p ± z * √(p(1-p)/n)

where:

- p is the sample proportion (82% or 0.82 in decimal form).

- z is the z-score corresponding to the desired confidence level. For a 95% confidence level, the z-score is approximately 1.96.

- n is the sample size (800).

Calculating the confidence interval:

CI = 0.82 ± 1.96 * √(0.82(1-0.82)/800)

CI = 0.82 ± 1.96 * √(0.82*0.18/800)

CI = 0.82 ± 1.96 * √(0.1476/800)

CI = 0.82 ± 1.96 * √0.0001845

CI ≈ 0.82 ± 1.96 * 0.01358

CI ≈ 0.82 ± 0.0266

The 95% confidence interval for the proportion of adults who believe in protecting the rights of those with unpopular views is approximately 0.7934 to 0.8466.

c. A 90% confidence interval would be wider than the 95% interval. The reason is that as we increase the confidence level, we need to account for a larger margin of error to be more certain about the interval capturing the true population proportion. As a result, the interval needs to be wider to provide a higher level of confidence.

The area of a parallelogram of width W and length L is A = W*L.

The area of a trapezoid of width W and different side lengths L1 and L2 is

A = W(L1 + L2)/2.  

To find the area of the trapezoid, take the average of the lengths L1 and L2 of the two parallel sides and call the result L.  Then apply the formula for the area of a parallelogram, given above).

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..

To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.

Substituting t = 4 into the equation:

A = 39500(0.86)^4

A ≈ 39500(0.5996)

A ≈ 23726.20

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.

This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

Roland's percent error is approximately 3.889%.

This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.

The positive sign indicates that Roland's measured value is slightly lower than the actual value.

To calculate Roland's percent error, we can use the formula:

Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100

Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:

Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100

Simplifying the expression within the absolute value:

Percent Error = (|-0.007| / 0.180) \(\times\) 100

Since the absolute value of -0.007 is 0.007, we have:

Percent Error = (0.007 / 0.180) \(\times\) 100

Calculating the division:

Percent Error = 0.03889 \(\times\) 100

Percent Error = 3.889%.

As x tends to negative one from the left, the value of f(x) tends to positive infinity. As x → -1⁻, f(x) → ∞.

In Mathematics and Geometry, the vertical asymptote of a function simply refers to the value of x (x-value) which makes its denominator equal to zero (0).

By critically observing the graph of this rational function f(x) shown below, we can logically deduce that its vertical asymptote is at x = -1 and x = 2, and its horizontal asymptote is at y = 3.

The value of iⁿ is -1 \(i^n\) = \(-i\).

Complex numbers are numbers which are of the form \(a + ib\), where a and b are real numbers and i is the imaginary number called iota whose value is \(i^2\) = -1.

We have to find the value of iⁿ if the remainder of  n/4 is 3.

The remainder of n/4 is 3 means that the value of n is 1 less than the multiple of 4.

When 1 is taken less to any of the multiple of 4, then the number will be an odd number.

So n is an odd number.

Now, the value of \(i^2\) = -1.

\(i^3\) = \(i^2\) × \(i\) = \(-i\)

\(i^4\) = \(-i\) × \(i\) = \(-i^2\) = 1

From the pattern it is seen that any number, n which is 1 less than the multiple of 4 will have, \(i^n\) = \(-i\).

Hence the value of \(i^n\) = \(-i\).

The average thickness of the metal sheet is 0.0423 inches.

In statistics, the mean is a measure of central tendency of a set of data. It is also referred to as the arithmetic mean and is calculated by adding up all the values in the data set and dividing by the total number of values.

Mean = (sum of all values) / (number of values)

For example, suppose we have the following set of data: 5, 7, 9, 11, 13. To find the mean, we add up all the values and divide by the total number of values, which is 5 in this case:

Mean = (5 + 7 + 9 + 11 + 13) / 5

Mean = 9

Therefore, the mean of this data set is 9.

The mean is a commonly used measure of central tendency because it takes into account all the values in the data set and is sensitive to changes in the data. However, it can be affected by outliers or extreme values in the data set, which can skew the results.

To find the average thickness of the sheet, we need to add the five measurements together and then divide by 5 (the number of measurements):

Average thickness = (0.0401 + 0.0417 + 0.0462 + 0.0407 + 0.0428) / 5

Average thickness = 0.0423 in

The exact values of the remaining trigonometric functions of θ are:

sin(θ) = √(1/64)

cos(θ) = -8

tan(θ) = -8√(1/64)

csc(θ) = 1

cot(θ) = -√(1/64) / 8

Given that sec(θ) = -8 and sin(θ) > 0, we can find the exact values of the remaining trigonometric functions using the Pythagorean identity:

sec^2(θ) = 1/sin^2(θ)

Substituting the value of sec(θ), we have:

(-8)^2 = 1/sin^2(θ)

64 = 1/sin^2(θ)

sin^2(θ) = 1/64

sin(θ) = ±√(1/64)

Since sin(θ) > 0, we take the positive square root:

sin(θ) = √(1/64)

Next, we use the reciprocal identity for cosecant:

csc(θ) = 1/sin(θ)

Substituting the value of sin(θ), we have:

csc(θ) = 1/√(1/64) = 8√(1/64) = 8/√(64) = 8/8 = 1

Next, we use the reciprocal identity for cotangent:

cot(θ) = 1/tan(θ)

We can find the value of tan(θ) using the definition:

tan(θ) = sin(θ) / cos(θ)

Substituting the values of sin(θ) and cos(θ), we have:

tan(θ) = √(1/64) / (-8) = -√(1/64) / 8

Finally, we use the reciprocal identity for a tangent:

tan(θ) = 1/cot(θ)

Substituting the value of cot(θ), we have:

tan(θ) = -8√(1/64)

Therefore, the exact values of the remaining trigonometric functions of θ are:

sin(θ) = √(1/64)
