Using the normal distribution, it is found that:

The z-score of a measure X of a variable that has mean represented by \(\mu\) and standard deviation represented by \(\sigma\) is given by the fraction presented as follows:

\(Z = \frac{X - \mu}{\sigma}\)

The mean and the standard deviation of the number of chips are given as follows:

\(\mu = 1262, \sigma = 118\)

The proportion of bags that has between 1026 and 1380 chocolate chips is the p-value of Z when X = 1380 subtracted by the p-value of Z when X = 1026, hence:

X = 1380:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (1380 - 1262)/118

Z = 1

Z = 1 has a p-value of 0.8413.

X = 1026:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (1026 - 1262)/118

Z = -2

Z = -2 has a p-value of 0.0228.

0.8413 - 0.0228 = 0.8185.

Hence the percentage is 81.85%.

The proportion that has fewer than 1144 chips is the p-value of Z when X = 1144, hence:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (1144 - 1262)/118

Z = -1

Z = -1 has a p-value of 0.1587.

Hence the percentage is of 15.87%.

The proportion that has more than 1498 chips is one subtracted by the p-value of Z when X = 1498, hence:

\(Z = \frac{X - \mu}{\sigma}\)

Z = (1498 - 1262)/118

Z = 2

Z = 2 has a p-value of 0.9772.

1 - 0.9772 = 0.0228

Hence the percentage is of 2.28%.

Group C ran more miles than Group D

the central value of a set of data is expressed by the average of a list of data. It is defined mathematically as the ratio of the total number of data points to the number of units in the list. In terms of statistics, the term "mean" also refers to the average of a certain set of numerical data. The average of 2, 3, and 4 is, for instance, (2+3+4)/3 = 9/3 = 3. The center value of 2, 3, and 4 in this instance is 3, thus. Finding the mean value of a bunch of numbers is the definition of average.

Average = Total Values / Total Values

Answer:

f(x) = x³ - 4x + 6

f'(x) = 3x² - 4

a) f'(2) = 3(2²) - 4 = 12 - 4 = 8

6 = 8(2) + b

6 = 16 + b

b = -10

y = 8x - 10

b) 3x² - 4 = 0

3x² = 4, so x = ±2/√3 = ±(2/3)√3

= ±1.1547

f(-(2/3)√3) = 9.0792

f((2/3)√3) = 2.9208

c) 3x² - 4 = 8

3x² = 12

x² = 4, so x = ±2

f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6

6 = -2(8) + b

6 = -16 + b

b = 22

y = 8x + 22

f(2) = 6

y = 8x - 10

The equation perpendicular to the tangent is y = -1/8x + 25/4

-The smallest slope on the curve is 2.92

The curve has the smallest slope at the point (1.15, 2.92)

The equations at tangent points are y = 8x + 16 and  y = 8x - 16

From the question, we have the following parameters that can be used in our computation:

y = x³ - 4x + 6

Differentiate

So, we have

f'(x) = 3x² - 4

The point is (2, 6)

So, we have

f'(2) = 3(2)² - 4

f'(2) = 8

The slope of the perpendicular line is

Slope = -1/8

So, we have

y = -1/8(x - 2) + 6

y = -1/8x + 25/4

We have

f'(x) = 3x² - 4

Set to 0

3x² - 4 = 0

Solve for x

x = √[4/3]

x = 1.15

So, we have

Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6

Smallest slope = 2.92

So, the smallest slope is 2.92 at (1.15, 2.92)

Here, we set f'(x) to 8

3x² - 4 = 8

Solve for x

x = ±2

Calculate y at x = ±2

y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)

y = (2)³ - 4(2) + 6 = 6: (2, 0)

The equations at these points are

y = 8x + 16

Answer:

Yes, Chris will score.

Step-by-step explanation:

To get the ball in the goal, the ball must be below 8ft (the height of the goal) when the ball passes the 25ft mark; ie, Chris will score if f(x)<8 when x=25:

f(x)=-0.05(x-16)²+11

f(25)=-0.05(25-16)²+11

=-0.05(9²)+11

=-0.05(81)+11

=11-4.05

=6.95

Since 6.95<8, we can see that Chris will score if Deshawn doesn't block the ball.

The estimated values of f'(2) and f'(8) are -4.5 and -8.5, respectively.

In programming, a function is a self-contained block of code that performs a specific task or set of tasks. It is a reusable piece of code that can be called multiple times from different parts of a program. Functions typically take inputs, called arguments or parameters, and produce outputs, which can be returned to the calling code.

Given by the question.

a.

To determine whether the function has a positive or negative first derivative, we can examine the change in values of f(t) between adjacent values of t. Since the values of f(t) decrease as t increases, the function appears to have a negative first derivative.

To determine the second derivative, we can examine the change in the first derivative. Since the first derivative is negative, it is decreasing as t increases, suggesting a negative second derivative.

Therefore, the function appears to have a negative first derivative and a negative second derivative.

b.

To estimate f'(2) and f'(8) using difference quotients to the right, we can use the following formula:

f'(t) ≈ [f (t + h) - f(t)] / h

where h is a small positive value. To estimate f'(2), we can use h = 2:

f'(2) ≈ [f (4) - f (2)] / 2 = (120 - 129) / 2 = -4.5

To estimate f'(8), we can use h = 2:

f'(8) ≈ [f (10) - f (8)] / 2 = (77 - 94) / 2 = -8.5

Step-by-step explanation:

Truly, I'm not sure what type of problem this is, but most people don't favor all the seasons. If there is more to the problem, I would be glad to help further.

Answer:

One possible way to estimate how many people out of 20 would say that they like all seasons is to use a simple random sample. A simple random sample is a subset of a population that is selected in such a way that every member of the population has an equal chance of being included. For example, one could use a random number generator to assign a number from 1 to 20 to each person in the population, and then select the first 20 numbers that appear. The sample would then consist of the people who have those numbers.

Using a simple random sample, one could ask each person in the sample whether they like all seasons or not, and then calculate the proportion of positive responses. This proportion is an estimate of the true proportion of people in the population who like all seasons. However, this estimate is not exact, and it may vary depending on the sample that is selected. To measure the uncertainty of the estimate, one could use a confidence interval. A confidence interval is a range of values that is likely to contain the true proportion with a certain level of confidence. For example, a 95% confidence interval means that if the sampling procedure was repeated many times, 95% of the intervals would contain the true proportion.

One way to construct a confidence interval for a proportion is to use the formula:

p ± z * sqrt(p * (1 - p) / n)

where p is the sample proportion, z is a critical value that depends on the level of confidence, and n is the sample size. For a 95% confidence interval, z is approximately 1.96. For example, if out of 20 people in the sample, 12 said that they like all seasons, then the sample proportion is 0.6, and the confidence interval is:

0.6 ± 1.96 * sqrt(0.6 * (1 - 0.6) / 20)

which simplifies to:

0.6 ± 0.22

or:

(0.38, 0.82)

This means that we are 95% confident that the true proportion of people who like all seasons in the population is between 0.38 and 0.82. Therefore, based on this sample and this confidence interval, we would expect between 8 and 16 people out of 20 to say that they like all seasons in the population.

The dollar value of total revenue at each price is $\(0\), $\(10\), $\(12\), $\(12\), $\(10\), and $\(6\). Total revenue will be the greatest at a price of $\(4\), with \(3\) units sold.

To find the dollar value of total revenue at each price, we can multiply the price by the corresponding quantity in the demand schedule:

Price: $\(6\)

Quantity: \(0\)

Total Revenue: $\(6 \times 0\) = $\(0\)

Price: $\(5\)

Quantity: \(2\)

Total Revenue: $\(5 \times 2\) = $\(10\)

Price: $\(4\)

Quantity: \(3\)

Total Revenue: $\(4 \times 3\) = $\(12\)

Price: $\(3\)

Quantity: \(4\)

Total Revenue: $\(3 \times 4\) = $\(12\)

Price: $\(2\)

Quantity: \(5\)

Total Revenue: $\(2 \times 5\) = $\(10\)

Price: $\(1\)

Quantity: \(6\)

Total Revenue: $\(1 \times 6\) = $\(6\)

To determine at which price the total revenue will be the greatest, we observe that the highest total revenue occurs at the price with the highest quantity sold. In this case, the price with the highest quantity is $\(3\), and the corresponding quantity sold is \(4\) units.

Therefore, at a price of $\(3\), the total revenue will be the greatest, with \(4\) units sold.

Answer:

In one month we have to pay an interest of $0.5.

Step-by-step explanation:

We are given that you borrow $60.00 at 10% interest and we have to find how much we have to pay in one month.

Let the Principal sum of money = P = $60

the rate of interest = R = 10%

Time period = T = \(\frac{1}{12}\)

Assuming the interest is simple interest, so the formula for simple interest is given by;

              Amount = Principal + Simple interest

                 A = P + ( \(\frac{\text{P}\times \text{R}\times \text{T}}{100}\) )

                 A = \(60 + \frac{60 \times 10 \times 1}{100 \times 12}\)

                 A = 60 + 0.5 = $60.5

So, in one month we have to pay an interest of $0.5.

Answer:

p = 9 when q = 5.

Step-by-step explanation:

p is inversely proportional to the square of q

This means that:

\(p = \frac{k}{q^2}\)

In which k is a constant multiplier.

p is 25 when q is 3

We use this to find k.

\(p = \frac{k}{q^2}\)

\(25 = \frac{k}{3^2}\)

\(k = 25*9 = 225\)

So

\(p = \frac{225}{q^2}\)

Determine p when q is equal to 5.

\(p = \frac{225}{q^2} = \frac{225}{5^2} = 9\)

p = 9 when q = 5.
