Answer:

1 quarter, 2 dimes, 2 nickels, and 1 penny.

a) The probability of selecting a jar with a weight between 848 and 854 grams can be determined by finding the area under the bell curve within that range.

Since the distribution is normal with a mean (u) of 850 grams and a standard deviation (σ) of 8 grams, we can calculate the z-scores for the lower and upper limits of the range. The z-score formula is (x - u) / σ, where x is the value, u is the mean, and σ is the standard deviation. For the lower limit, the z-score is (848 - 850) / 8 = -0.25, and for the upper limit, the z-score is (854 - 850) / 8 = 0.5.The probability of the weight being between 848 and 854 grams is the difference between these probabilities.

b) To find the probability of a random sample of 32 jars having a mean weight between 848 and 854 grams, we can use the Central Limit Theorem (CLT). The CLT states that the distribution of sample means approaches a normal distribution as the sample size increases, regardless of the shape of the population distribution. In this case, since the sample size is 32, we can assume that the distribution of sample means will be approximately normal. The mean of the sample means will be the same as the population mean, which is 850 grams. The standard deviation of the sample means, also known as the standard error of the mean (SE), is calculated by dividing the population standard deviation by the square root of the sample size, i.e., σ / √n. In this case, the SE is 8 / √32 ≈ 1.41 grams. We can then calculate the z-scores for the lower and upper limits of the range using the formula (x - u) / SE, where x is the value, u is the mean, and SE is the standard error.

c) To find the probability that a random sample of 32 jars has a mean weight greater than 853 grams, we can again use the Central Limit Theorem. The mean of the sample means will still be 850 grams, but the standard deviation of the sample means (SE) remains 1.41 grams.The probability can be determined by finding the area under the standard normal curve to the right of this z-score.

The probability of getting at least 1 paperback when a person takes 3 books at random out of 15 books will be 0.736.

The area of mathematics known as probability studies potential outcomes of events as well as their relative probabilities and distributions. It is based on the likelihood that something will occur. The justification for probability serves as the main foundation for theoretical probability. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur.

Here,

Total selection=15C3

selection of none being paperback=10C3

Required probability=(15C3-10C3)/15C3

Part A: -6 and -1

Part B: (x - 6)(x - 1) = 0

Part C: x = 6 and x = 1

    We need to find two numbers that add up -7 and multiply to 6.

    We know that 6 * 1 = 6, but 6 + 1 is not -7. However, -6 * -1 = 6 and -6 + -1 = -7. Our factors are -6 and -1.

    Next, we will rewrite this in factored form. Using the factors above, the form is as follows.

(x - 6)(x - 1) = 0

    Lastly, we will use the zero product property to solve. This states that if xy = 0, then x = 0 and y = 0 because anything times zero is equal to zero.

x - 6 = 0       x - 1 = 0

x = 6             x = 1

To determine if the series 1+1/16+1/81+1/256+1/625+... is convergent or divergent, we need to apply the convergence tests. The series is a geometric series with a common ratio of 1/4 (each term is one-fourth of the previous term). The formula for the sum of an infinite geometric series is a/(1-r), where a is the first term and r is the common ratio. In this case, a = 1 and r = 1/4.
Using the formula, we get:
sum = 1/(1-1/4) = 1/(3/4) = 4/3

Answer: &1,552.50

Step-by-step explanation: Step 1: Multiply Shaquana and Briana deposits of $230 times both interest rates.
Step 2: Shaquana dollar amount adds up to $1006.25. Brianna’s dollar amount adds up to $1,092.50.
Step 3: Multiply both totals times 18yrs.
Step 4: Subtract 18,112.50 from 19,665 and you find that Brianna will have $1552.50 more than Shaquana.

Brianna would have $290 more in her account than Shaquana after 18 years.

The final amount in Shaquana's account is:

\(A=230e^0^.^0^4^3^7^5^\times^1^8\)

\(A=230e^0^.^7^8^7^5\)

A=230×1.082

= $249

For Brianna, we have:

P = $230

r = 4.75% / 12 = 0.0039583333

t = 18 × 12 = 216 months

So, the final amount in Brianna's account is:

A = $230×(1 + 0.0039583333)²¹⁶

A=230(1.00395)²¹⁶

A=230×2.34

A=538.2

Therefore, the difference in the final amounts is:

$538.2 - $249= $289.2

So, Brianna would have $290 more in her account than Shaquana after 18 years.

The arc length is D) 3.14 meters.

What is arc length?

In mathematics, an arc is a portion of a curve that can be thought of as a segment of the curve. An arc is a connected set of points on a curve, usually a portion of a circle.

It is defined by two endpoints and all the points along the curve between them. The length of an arc is the distance along the curve between its two endpoints.

The distance along the curved line that forms the arc (a section of a circle) is measured using the arc length formula.

                                      \(A_L=\frac{\theta}{360\textdegree}2\pi r\)

Here the give circle Radius PR = 3m and θ=60°.

Now using arc length formula then,

=> Arc length \(A_L=\frac{\theta}{360\textdegree}2\pi r\)

=> \(A_L=\frac{60}{360} \times2\times3.14\times3\)

=> \(A_L=\frac{1}{6}\times2\times3.14\times3\)

It will take them 3 days to paint the building if they work together on it except for 1 day when the painter is ill and the apprentice works alone is the answer.

Given that a painter can paint a building in 4 days and his apprentice can do it in 6 days, the following steps can be taken to find out the time taken to paint the building when they work together on it except for 1 day when the painter is ill and the apprentice works alone.

Step 1: Let's find the painter's work efficiency.

The painter can paint a building in 4 days. It means, in 1 day, the painter can complete 1/4 of the work.(1/4) × (4 days) = 1 work done

Therefore, the painter can complete 1 work in 1 day.

Step 2: Let's find the apprentice's work efficiency.

The apprentice can paint a building in 6 days. It means, in 1 day, the apprentice can complete 1/6 of the work. (1/6) × (6 days) = 1 work done

Therefore, the apprentice can complete 1 work in 1 day.

Step 3: Let's find out their combined work efficiency.

In 1 day, the painter can complete 1 work and the apprentice can complete 1 work.

So, in 1 day, their combined work efficiency = 1 + 1 = 2 works done.

Step 4: Let's find out the time taken to complete the work if they work together on it except for 1 day when the painter is ill and the apprentice works alone. If they work together for x days (except for 1 day when the painter is ill and the apprentice works alone), then, the following equation can be formed: Painter's work done in x days + Apprentice's work done in x days = Total work to be done.

Painter's work done in x days = (1/4) × (x - 1) = (x - 1)/4.

Apprentice's work done in x days = (1/6) × x = x/6.

Total work to be done = 1.

So, the equation becomes:(x - 1)/4 + x/6 = 1.

⇒ 3(x - 1)/12 + 2x/12 = 1.

⇒ (3x - 3 + 2x)/12 = 1.

⇒ 5x - 3 = 12.

⇒ 5x = 15.

⇒ x = 3.

Therefore, it will take them 3 days to paint the building if they work together on it except for 1 day when the painter is ill and the apprentice works alone.

In fact, some time series may require more complex models such as state-space models, VAR models, or GARCH models to capture the underlying dynamics.

Regarding the other statements:

Spikes in the autocorrelation function do indicate autoregressive terms, as autocorrelation measures the correlation between a time series and its past values.

Spikes in the partial-autocorrelation function do indicate moving-average terms, as partial-autocorrelation measures the correlation between a time series and its past values, controlling for the effects of intermediate lags.
