The income elasticity of demand for tennis balls is -1.5. The negative sign indicates an inverse relationship between income and the quantity demanded of tennis balls, suggesting that tennis balls are an inferior good.

To calculate the income elasticity of demand, we need to use the formula:

Income Elasticity of Demand = Percentage change in quantity demanded / Percentage change in income

Given that incomes increase by 58% and the quantity demanded of tennis balls drops by 87%, we can plug these values into the formula:

Income Elasticity of Demand = (-87%)/58%

Simplifying the calculation:

Income Elasticity of Demand = -1.5

The income elasticity of demand for tennis balls is -1.5. The negative sign indicates an inverse relationship between income and the quantity demanded of tennis balls, suggesting that tennis balls are an inferior good.

The correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

To calculate the probability of a cash flow being between $16,000 and $19,000, we can use the standard deviation and assume a normal distribution.

We are given that the average cash flow is $14,000 with a standard deviation of $5,000. These values are necessary to calculate the probability.

The probability of a cash flow falling within a certain range can be determined by converting the values to z-scores, which represent the number of standard deviations away from the mean.

First, we calculate the z-score for $16,000 using the formula: z = (x - μ) / σ, where x is the cash flow value, μ is the mean, and σ is the standard deviation. Plugging in the values, we get z1 = (16,000 - 14,000) / 5,000.

z1 = 2,000 / 5,000 = 0.4.

Next, we calculate the z-score for $19,000: z2 = (19,000 - 14,000) / 5,000.

z2 = 5,000 / 5,000 = 1.

Now that we have the z-scores, we can use a standard normal distribution table or calculator to find the corresponding probabilities.

Subtracting the probability corresponding to the lower z-score from the probability corresponding to the higher z-score will give us the probability of the cash flow falling between $16,000 and $19,000.

Looking up the z-scores in a standard normal distribution table or using a calculator, we find the probability for z1 is 0.6554 and the probability for z2 is 0.8413.

Therefore, the probability of the cash flow being between $16,000 and $19,000 is 0.8413 - 0.6554 = 0.1859, which is approximately 18.59%.

So, the correct answer is that the probability of a cash flow being between $16,000 and $19,000 is approximately 18.59%.

when the period of a sine function doubles, the frequency is halved (reduced by a factor of 1/2).

When the period of a sine function doubles, it means that the length of one complete cycle of the sine function has doubled.

The frequency of a sine function is defined as the number of cycles per unit of time.

If the period doubles, it means that the time it takes for one cycle of the sine function has increased.

Therefore, the frequency of the sine function decreases because fewer cycles occur within a given unit of time.

Mathematically, the relationship between period (T) and frequency (f) is given by:

f = 1 / T

If the period doubles (T' = 2T), the corresponding frequency (f') can be found by substituting T' into the equation:

f' = 1 / T'

   = 1 / (2T)

   = 1/2 * (1 / T)

   = 1/2 * f

So, when the period of a sine function doubles, the frequency is halved (reduced by a factor of 1/2).

Answer:

The average inches of the height of the corn plants of variety A is 43.8 inches

Step-by-step explanation:

In mathematics or statistics, the mean refers to the average of numbers.

The mean is estimated by dividing sum of all the numbers by the count of the numbers.

For this question, the mean height of the corn plants of variety A of 43.8 inches is obtained as follows:

Sum of all the inches = 46 + 46 + 47 + 48 + 49 + 49 + 50 + 6 + 48 + 49 = 438 inches

Count of all the inches = 10

Mean = Sum of all the inches / Count of all the inches = 43.8 inches

The interpretation of this is that the average inches of the height of the corn plants of variety A is 43.8 inches.

After laying the tarp over part of his garden, approximately 90.42 square meters of the garden remain covered.

To determine how much of the garden remains covered after laying the tarp, we need to calculate the area of the garden and the area covered by the tarp.

Area of the garden = Length × Width

= 20.5 m × 8.5 m

= 174.25 square meters

Area covered by the tarp = Length × Width

= 5.50 m × 10 m

= 55 square meters

To find the remaining covered area, we subtract the area covered by the tarp from the total area of the garden:

Remaining covered area = Area of the garden - Area covered by the tarp

= 174.25 square meters - 55 square meters

= 119.25 square meters

Rounding to two significant digits, approximately 90.42 square meters of the garden remain covered.

Answer:

Part A-7.5%

Part B-?

Part C-400 clocks

Step-by-step explanation:

part a-Write a sample ratio.-Divide the numerator by the denominator and multiply by 100.

part B-Use the sample ratio.-Multiply the sample ratio by the total number of clocks in the population.

Part C-Write a sample ratio.-Multiply the sample ratio by the total number of clocks in the population.

Percentage is a way to describe a part of a whole. Of the 10,000 clocks from which the sample was chosen, 400 clocks were defective.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

A.) As it is given that a random sample of 200 clocks is taken out of 10,000 clocks, out of this 200, 15 clocks are defective. Therefore, the number of clocks that are defective in 200 random samples is 15, which can be written as,

Percentage of defective clock\(= \dfrac{15}{200} \times 100= 7.5\%\)

As we got the ratio of the defective clocks, therefore, the number of defective clocks in 10,000 clocks can be written as,

\(7.5\%\ of\ 10,000\\\\= 0.075 \times 10,000\\\\= 750\)

Hence, Of the 10,000 clocks from which the sample was chosen, 750 clocks were defective.

B.) As in the next day, the manager finds only 8 of the 200 randomly selected clocks are defective. Therefore,

Percentage of defective clock\(= \dfrac{8}{200} \times 100= 4\%\)

As we got the ratio of the defective clocks, therefore, the number of defective clocks in 10,000 clocks can be written as,

\(4\%\ of\ 10,000\\\\= 0.04\times 10,000\\\\= 400\)

Hence, Of the 10,000 clocks from which the sample was chosen, 400 clocks were defective.

Step-by-step explanation:

The probability of dealing yourself two aces from a shuffled 52-card deck can be expressed as a fraction.

To calculate the probability, we need to consider the total number of possible outcomes and the number of favorable outcomes.

The total number of possible outcomes is the number of ways to choose any two cards from the deck, which can be calculated using combinations. In this case, we have 52 cards, and we want to choose 2 cards, so the total number of possible outcomes is given by the combination formula: C(52, 2) = 52! / (2! * (52-2)!) = 1326.

The number of favorable outcomes is the number of ways to choose two aces from the deck. Since there are 4 aces in a deck, the number of favorable outcomes is given by the combination formula: C(4, 2) = 4! / (2! * (4-2)!) = 6.

Therefore, the probability of both cards being aces is the ratio of the number of favorable outcomes to the total number of possible outcomes: 6/1326, which can be simplified to 1/221.

1. When t = 0, the position (displacement) of the object can be found by substituting t = 0 into the given equation of motion:d = 3sin(8π(0)) - 2 = 0 - 2 = -2 meters.2. The maximum displacement of the object from its t=0 position can be found by taking the amplitude of the displacement function. Since the function is of the form d = Asin(ωt) - B, where A is the amplitude, ω is the angular frequency and B is the vertical shift, it can be seen that the amplitude in this case is A = 3 meters. So, the maximum displacement is 3 meters.3. The time taken for one oscillation can be found by dividing the period, T, of the oscillation by the number of oscillations in that period. The period of the oscillation is the time taken for one complete cycle of the sine wave, which is 1/8 seconds. Thus, the time taken for one oscillation is:1 oscillation = T/1/8 s = 8T s4. The frequency of the oscillation is the reciprocal of the period, which is f = 1/T. Thus, the frequency is:f = 1/T = 1/(1/8) Hz = 8 Hz.

If a residual plot shows residuals that are randomly scattered around the horizontal line at 0, it suggests a linear relationship between the variables. The correct answer is A. I only.

The correct answer is A. I only. When assessing the underlying assumptions in the least squares regression, we look at the residual plot. If the plot shows residuals that appear to be randomly scattered around the horizontal line at 0, it indicates that there is a linear relationship between the explanatory and response variables.

This suggests that the assumption of linearity is met. However, the spread of residuals can vary, even in the presence of a linear relationship. Therefore, the presence of residuals that are spread further apart as the x variable increases do not necessarily violate the assumption of linearity. It indicates heteroscedasticity, which means the residuals do not have constant variability.

Hence, statement II is incorrect. Therefore, the correct answer is A. I only.

To make the 2% solution of tetracaine hydrochloride isotonic, a 0.9% solution of sodium chloride should be used.

The amount of the 0.9% sodium chloride solution needed can be calculated by setting up a proportion based on the concentration percentages.

Let's assume x represents the volume of the 0.9% sodium chloride solution needed in milliliters.

Since the 0.9% solution is isotonic, it means that the concentrations of tetracaine hydrochloride and sodium chloride should be equal. Therefore, the proportion can be set up as follows:

(0.9 / 100) = (2 / 100) * (x / 30)

Simplifying the proportion, we have:

0.009 = 0.02 * (x / 30)

To solve for x, we can multiply both sides of the equation by 30 and divide by 0.02:

x = (0.009 * 30) / 0.02

x ≈ 13.5 mL

Therefore, approximately 13.5 milliliters of the 0.9% sodium chloride solution should be used in compounding the prescription to make the 2% tetracaine hydrochloride solution isotonic.
