The correct answer is option C: 27.6 to 29.6 pounds.

To calculate the 95% confidence interval for the true mean weight, μ, of all packages received by the parcel service, we can use the following formula:

CI = X ± (tα/2)(s/√n)

where:

X is the sample mean weight

tα/2 is the t-value from the t-distribution with (n - 1) degrees of freedom and α/2 level of significance (α/2 = 0.025 for a 95% confidence interval)

s is the sample standard deviation of weights

n is the sample size

We are given that the sample size is n = 49 and the sample mean weight is X = 28.6 pounds. We do not have the sample standard deviation, so we will assume it is unknown and use a t-distribution to estimate the standard error of the sample mean.

We want to calculate the 95% confidence interval, so α/2 = 0.025 and the degrees of freedom are (n - 1) = 48. From a t-distribution table, the t-value for a 95% confidence interval with 48 degrees of freedom is approximately 2.01.

Now we need to estimate the sample standard deviation, s, using the sample data. We can use the formula:

s = sqrt[ Σ(xi - X)² / (n - 1) ]

where xi is the weight of the ith package in the sample.

Without the actual data values, we cannot compute the exact value of s, but we can estimate it using the sample variance. We know that:

s² = Σ(xi - X)² / (n - 1) = (49 - 1) / 48 * s²

So, an estimate of s is:

s = sqrt[ (SS / (n - 1)) ] = sqrt[ (Σ(xi - X)² / (n - 1)) ]

where SS is the sum of squares of deviations of the sample data from the mean.

Assuming the sample standard deviation is unknown and using the above formula, we can estimate s as:

s ≈ 2.7 pounds

Substituting the known values into the formula for the confidence interval, we have:

CI = X ± (tα/2)(s/√n)

= 28.6 ± (2.01)(2.7/√49)

= 28.6 ± 0.99

Therefore, the 95% confidence interval for the true mean weight, μ, of all packages received by the parcel service is (28.6 - 0.99, 28.6 + 0.99), or approximately (27.6, 29.6) pounds.

So, the correct answer is option C: 27.6 to 29.6 pounds.

The possible rational zeros of the function g(x) = 3x³ - 5x² + 8x + 7 are

±1, ±7, ±1/3, and ±7/3.

To find the possible rational zeros of the function

g(x) = 3x³ - 5x² + 8x + 7, we can use the rational zeros theorem. According to the theorem, the possible rational zeros are of the form p/q, where p is a factor of the constant term (7) and q is a factor of the leading coefficient (3).

The factors of 7 are ±1 and ±7, and the factors of 3 are ±1 and ±3. So, the possible rational zeros are ±1, ±7, ±1/3, and ±7/3.

Therefore, the possible rational zeros of the function

g(x) = 3x³ - 5x² + 8x + 7 are ±1, ±7, ±1/3, and ±7/3. These are all the potential values of x for which g(x) could be equal to zero.

It is important to note that while these values are possible rational zeros, they are not guaranteed to be zeros of the function. Additional analysis or calculations would be needed to determine which of these possible zeros are actually valid zeros of the function.

Step-by-step explanation:

An exponential function to model the quail population is y = 765(1+0.16)ⁿ and the approximate population be after 4 years is 1384.65 quails.

Population growth is seen to increase at an exponential rate. We use the following to model this growth.

y = A₀(1 + r)ⁿ

where

y = value at time

A₀ = original value

r = rate of growth

n = time elapsed

An exponential function that models the quail population is set up like:

y = 765(1+0.16)ⁿ

so that, for example, if we wanted to figure out the population at time (4 years), then we would set up the function as follows,

y = 765(1+0.16)⁴

y = 765(1.16)⁴

y = 765* 1.81

to get

y = 1384.65 quails after 4 year has elapsed.

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0.

Several real-world scenarios use exponential functions, including population increase, compound interest, radioactive decay, and the spread of diseases. For instance, an exponential function may be used to simulate the expansion of a bacterial population, with the rate of increase being proportional to the population size. Similarly, compound interest, which applies the rate of interest to the principal sum across a number of periods, can be represented by an exponential function.

Positive value of a vertically stretches the graph of f when a > 1 or shrinks the graph of f when a < 1. h translates the graph of f to the left when h < 0 or right when h > 0 and k translates the graph of f up when k > 0 and down when k < 0.

Answer:-250,000

Step-by-step explanation:

A price of $75 per unit will yield maximum total revenue for the wholesaler.

To find the price that will yield maximum total revenue, we need to use the concept of elasticity of demand.

Elasticity of demand measures the responsiveness of the quantity demanded to a change in price.

The formula for the price elasticity of demand is:

E = (percent change in quantity demanded) / (percent change in price)

If E is greater than 1, demand is considered elastic, meaning that a change in price will result in a more than proportional change in quantity demanded.

If E is less than 1, demand is considered inelastic, meaning that a change in price will result in a less than proportional change in quantity demanded.

If E is equal to 1, demand is unit elastic, meaning that a change in price will result in a proportional change in quantity demanded.

We know that before the price increase, the wholesaler was selling 250 units per week at a price of $40 per unit.

After the price increase, the wholesaler was selling 225 units per week at a price of $45 per unit.

Using these values, we can calculate the price elasticity of demand as follows:

E = ((225 - 250) / 250) / ((45 - 40) / 40) = -0.5

The negative sign indicates that the relationship between price and quantity demanded is inverse.

Also, we see that the absolute value of E is less than 1, indicating that demand is inelastic.

This means that a price increase results in a less than proportional decrease in quantity demanded.

Now, to find the price that will yield maximum total revenue, we can use the following formula:

P* = E / (E - 1) * C

Where P* is the price that will yield maximum total revenue, E is the price elasticity of demand, and C is the current price that the wholesaler is charging.

Plugging in the values we know, we get:

P* = (-0.5) / (-0.5 - 1) * 45 = $75.

To calculate the t observed value for the slope, we would need additional information such as the sample size, the standard error of the slope estimate (seb1), and the degrees of freedom (df).

The t observed value can be calculated using the formula:

t_observed = sb1 / seb1

Where:

sb1 is the estimated standard deviation of the slope (given as 0.1713)

seb1 is the standard error of the slope estimate, which depends on the sample size and other factors

df represents the degrees of freedom, which also depends on the sample size and the number of predictors in the regression model

The height of the can is approximately 9.74 centimeter.

The surface area of a cylinder is the total area of the curved and flat surfaces that make up the cylinder. It can be calculated using the formula:

SA = 2πr² + 2πrh

where r is the radius of the cylinder and h is its height.

In this case, we are given that the diameter of the can is 4 cm, which means the radius is 2 cm.

We are also given that the surface area is 130 square centimeters. Substituting these values into the formula, we get:

130 = 2π(2)² + 2π(2)h

Simplifying this equation, we get:

130 = 8π + 4πh

Subtracting 8π from both sides, we get:

122 = 4πh

Dividing both sides by 4π, we get:

h = 122/(4π) ≈ 9.74 cm (rounded to the nearest hundredth using 3.14 for π)

Therefore, the height of the can is approximately 9.74 cm.
