Answer:
10%
Step-by-step explanation:
Find f. F ' ( x ) = √ x ( 6 + 10 x ) f ( 1 ) = 13
Based on the provided informations, the function f(x) is calculated out to be f(x) = \($\frac{1}{25}(6+10x)^{\frac{5}{2}}+13-\frac{1}{25}(16)^{\frac{5}{2}}$\)
We can find the function f(x) by integrating the given derivative function f'(x). Using the power rule of integration, we have:
\(\int \sqrt{x(6+10x)} dx\)
We can simplify this expression by using substitution. Let u = 6 + 10x, then du/dx = 10 and dx = du/10. Substituting these into the integral, we have:
\($f(x) = \int \sqrt{x(6+10x)} dx\)
\(= \frac{1}{10}\int \sqrt{x}u^{\frac{1}{2}}du\)
\(= \frac{1}{10}\int u^{\frac{3}{2}}du\)
\(= \frac{1}{10}\cdot \frac{2}{5}u^{\frac{5}{2}}+C\)
\(= \frac{1}{25}(6+10x)^{\frac{5}{2}}+C$\)
where C is the constant of integration.
Using the given initial condition f(1) = 13, we can solve for the constant of integration:
\($f(x) = \frac{1}{25}(6+10x)^{\frac{5}{2}} + C\)
\(13 = \frac{1}{25}(16 +10x)^{\frac{5}{2}} +C\right)$\)
\(C= 13 - \frac{1}{25}(16)^{\frac{5}{2}}\right)$\)
Therefore, the function f(x) is: \($\frac{1}{25}(6+10x)^{\frac{5}{2}}+13-\frac{1}{25}(16)^{\frac{5}{2}}$\)

In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 35 and a standard deviation of 8. Using the empirical rule (as presented in the book), what is the approximate percentage of daily phone calls numbering between 27 and 43
The approximately 68% of daily phone calls in the mid-size company are expected to fall between 27 and 43.
According to the empirical rule, also known as the 68-95-99.7 rule, for a bell-shaped distribution, approximately 68% of the data falls within one standard deviation of the mean. In this case, the mean is 35 and the standard deviation is 8.
Therefore, the range between 27 (mean - one standard deviation) and 43 (mean + one standard deviation) represents the middle 68% of the distribution. This means that approximately 68% of daily phone calls in the company are expected to fall within this range.

The researchers select a simple random sample of 50 registered voters from each county in the state and ask whether they approve or disapprove of the measure. This is an example of
This is an example of a (B) stratified sample.
What is the stratified sample?When subpopulations within an overall population differ, it may be advantageous in statistical surveys to sample each subpopulation (stratum) independently. Before sampling, stratification is the process of dividing the population into homogeneous subgroups. The strata should define a population division. That is, it should be collectively exhaustive and mutually exclusive: every element in the population should be assigned to only one stratum. Then, within each stratum, simple random sampling is used. The goal is to improve sample precision by reducing sampling error. It can generate a weighted mean with less variability than a simple random sample of the population's arithmetic mean.Therefore, this is an example of a (B) stratified sample.

What value of z should we use when making a 93% confidence interval for p?.
The crucial value (z) relies on the desired level of confidence and is predicated on a normal distribution when creating a confidence interval for a proportion (p) with a confidence level of 93%.
A 93% confidence level in this instance translates to an alpha level of 0.07 (1 - 0.93 = 0.07) that is split evenly between the two tails. In the usual normal distribution table, we search for the value that falls within the range of 0.07 to find the proper z-value. A 93% confidence level corresponds to a z-value of roughly 1.81. The confidence interval for the proportion p may be calculated using this number and provides a range where the genuine proportion is like to fall.

the mean wait time for a drive-through chain is 193.2 seconds with a standard deviation of 29.5 seconds. what is the probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds? (write answer round to whole number like 91%).
The probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds is 94%.
To solve this problem, we can use the Central Limit Theorem, which states that the distribution of sample means is approximately normal for large sample sizes.
First, we need to calculate the standard error of the mean (SEM) using the formula
SEM = standard deviation / sqrt(sample size)
SEM = 29.5 / sqrt(45) = 4.4
Next, we can standardize the sample mean using the formula
z = (x - μ) / SEM
where x is the sample mean, μ is the population mean, and SEM is the standard error of the mean.
For the lower limit, we have
z = (185.7 - 193.2) / 4.4 = -1.70
For the upper limit, we have
z = (206.5 - 193.2) / 4.4 = 3.02
We can use a standard normal distribution table or calculator to find the probabilities associated with these z-scores.
The probability of z being between -1.70 and 3.02 is approximately 0.9429 or 94%. Therefore, the probability that for a random sample of 45 wait times, the mean is between 185.7 and 206.5 seconds is 94%.

A small software company will bid on a major contract. It anticipates a profit of $10,000 if it gets it, but thinks there is only a 40% chance of that happening. a) What's the expected profit? b) Find the standard deviation for the profit. a) The expected profit is $ (Round to the nearest dollar as needed.) b) The standard deviation is $ (Round to the nearest dollar as needed.)
a)The expected profit is $4,000. b)The standard deviation for the profit is approximately $4,898.98.
a) To calculate the expected profit, we multiply the profit by the probability of it happening:
Expected profit = Profit * Probability
Given:
Profit = $10,000
Probability = 40% = 0.4
Expected profit = $10,000 * 0.4 = $4,000
Therefore, the expected profit is $4,000.
b) To find the standard deviation for the profit, we need more information about the probability distribution of the profit. If we assume that the profit follows a Bernoulli distribution (with only two possible outcomes: getting the contract or not), we can calculate the standard deviation using the formula:
Standard deviation = √(Probability * (1 - Probability) * Profit^2)
Given:
Profit = $10,000
Probability = 40% = 0.4
Standard deviation = √\((0.4 * (1 - 0.4) * $10,000^2)\)
= √(0.4 * 0.6 * $100,000,000)
= √(24,000,000)
≈ $4,898.98
Therefore, the standard deviation for the profit is approximately $4,898.98.

Initially a slice of pizza costs $5, and a change in the market makes the price of a slice of pizza $13; before the change in the price of a slice of pizza, Raquel consumed 15 cups of Sprite per week and now consumes 17 cups of Sprite per week. Indicate whether the changes are positive or negative and keep 2 decimals. (Use the midpoint formula and averages for all your calculations) What is the percentage change in the price of a slice of pizza? What is the percentage change in the quantity of Sprite? What is the Cross Price Elasticity of Demand? In this example, are Sprite and a slice of pizza complements or substitutes? Complements Substitures
1. To calculate the percentage change in the price of a slice of pizza, we can use the midpoint formula:
Percentage change = [(New value - Old value) / ((New value + Old value) / 2)] * 100
Old value: $5 New value: $13
Percentage change = [($13 - $5) / (($13 + $5) / 2)] * 100 Percentage change = [(8) / (18 / 2)] * 100 Percentage change = (8 / 9) * 100 Percentage change = 88.89%
The percentage change in the price of a slice of pizza is approximately 88.89%.
2. To calculate the percentage change in the quantity of Sprite, we can use the same formula:
Old value: 15 cups New value: 17 cups
Percentage change = [(17 - 15) / ((17 + 15) / 2)] * 100 Percentage change = (2 / 16) * 100 Percentage change = 12.5%
The percentage change in the quantity of Sprite is 12.5%.
3. To calculate the Cross Price Elasticity of Demand, we use the formula:
Cross Price Elasticity = [(New quantity - Old quantity) / ((New quantity + Old quantity) / 2)] / [(New price - Old price) / ((New price + Old price) / 2)]
Old price of pizza: $5 New price of pizza: $13 Old quantity of Sprite: 15 cups New quantity of Sprite: 17 cups
Cross Price Elasticity = [(17 - 15) / ((17 + 15) / 2)] / [(13 - 5) / ((13 + 5) / 2)] Cross Price Elasticity = (2 / 16) / (8 / 9) Cross Price Elasticity = (2 / 16) * (9 / 8) Cross Price Elasticity = 0.28125
The Cross Price Elasticity of Demand is 0.28125.
4. Based on the positive percentage change in the price of a slice of pizza and the positive Cross Price Elasticity of Demand, we can conclude that Sprite and a slice of pizza are substitutes.
In summary:
The percentage change in the price of a slice of pizza is approximately 88.89%.
The percentage change in the quantity of Sprite is 12.5%.
The Cross Price Elasticity of Demand is 0.28125.
Sprite and a slice of pizza are substitutes.
