The position of the particle at time t is given by s = f(t) = t^3 - 15t^2 + 72t, So, at t = 3 seconds, the particle's position is 108 feet.

Let's proceed with the calculation.

The law of motion for the particle is given by the function f(t) = t^3 - 15t^2 + 72t, where t represents time in seconds and s represents the displacement of the particle in feet.

To calculate the position of the particle at a specific time t, we substitute the value of t into the function f(t).

For example, let's calculate the position of the particle at t = 3 seconds:

f(3) = (3)^3 - 15(3)^2 + 72(3)
     = 27 - 135 + 216
     = 108 feet

So, at t = 3 seconds, the particle's position is 108 feet.

The correct answer is b.

The child's height is 1.5 standard deviations below the mean height for children his age.

A z-score is a measure of how many standard deviations an observation is away from the mean of the distribution. A z-score of -1.5 means that the child's height is 1.5 standard deviations below the mean height for children his age. This indicates that the child's height is lower than the average height of his peers.

Option a is incorrect because the z-score does not measure what the model predicted for the child's height, but rather how far the child's height deviates from the mean height of his peers.

Option c is incorrect because the z-score does not measure how low or high the child's height is in absolute terms, but rather how far it deviates from the mean.

Option d is partially correct but not specific enough, as the z-score tells us how much lower the child's height is compared to the mean, but not whether it is unusually low or not.

Option e is incorrect because the z-score is a measure of standard deviations, not inches.

If a child's height has a z-score of -1.5, it means that the child's height is 1.5 standard deviations below the mean height for children his age. So the correct option is C.

The z-score measures the number of standard deviations a particular data point is from the mean of the distribution. A z-score of -1.5 indicates that the child's height is 1.5 standard deviations below the mean height for children his age. Since the z-score is negative, it means that the child's height is below the mean height for his age group. In other words, the child is shorter than what the model predicted for his height.

The mean height for children his age represents the average height of all children in that age group. Standard deviation measures the amount of variability in the height measurements of the children in that age group. A z-score of -1.5 indicates that the child's height is 1.5 standard deviations below the mean height for his age group. This means that the child's height is significantly lower than that of his peers.

Therefore, if a child's height has a z-score of -1.5, it means that the child's height is significantly lower than the mean height for children his age, and he is shorter than what the model predicted for his height.

Since the 1980s, the percentage of Americans who are members of a workplace union has declined significantly.

According to data from the Bureau of Labor Statistics, the union membership rate in the United States has experienced a substantial decrease over the past few decades. In the 1980s, the union membership rate was around 20% of the total workforce. However, as of the most recent available data, which is from 2020, the union membership rate stands at approximately 10.8%.

This indicates a decline of about 9.2 percentage points since the 1980s. The reasons for this decline include various factors such as changes in labor laws, economic shifts, and shifts in industries and employment patterns.

Snowballing payments according to the highest interest rate is likely to save the most money in the long run.

Option (A) is correct.

What is the interest rate?

An interest rate is the amount charged, expressed as a percentage of principal, by a lender to a borrower for the use of assets, such as money or property. It is typically calculated as an annual percentage of the principal amount, and represents the cost of borrowing or the reward for saving.

Snowballing payments according to the highest interest rate is likely to save the most money in the long run.

This method involves paying off the credit card with the highest interest rate first, while continuing to make minimum payments on the other cards. Once the card with the highest interest rate is paid off, the next highest interest rate card is tackled, and so on.

By prioritizing the highest interest rate cards, the overall amount of interest paid will be lower than if the payments were made based on the lowest balance or a fixed payment each month. Additionally, paying only the minimum balance each month will result in much higher interest charges and a longer payoff period.

While the snowball method of paying off the lowest balance may provide psychological benefits by creating a sense of progress and momentum, it may not always be the most cost-effective way to pay off debt.

Hence, Snowballing payments according to the highest interest rate is likely to save the most money in the long run.

Option (A) is correct.

The inequality that represents the the possible numbers of x pairs of socks you can buy when you buy 2 pairs of sneakers, using a system of equations, is of:

y ≤ 7.

A system of equations is a set of equations involving multiple variables that are related, and then operations are made to solve these equations and identify the numeric value of each variable in the context of the problem from which the system was built.

For this problem, the variables are given as follows:

You have a $250 card to use at a sporting goods store. Each pair of sneakers is worth $80 and a pair of socks costs $12, hence the inequality regarding the total spending is:

80x + 12y ≤ 250.

When two pairs of sneakers are bought, we have that:

x = 2.

Hence the inequality regarding how many pairs of socks can be bought is:

80(2) + 12y ≤ 250.

160 + 12y ≤ 250.

12y ≤ 90

y ≤ 90/12

y ≤ 7. (rounded down, as you can buy 7 pairs of socks but not 8).

The cost of a pair of socks is of $12.

a)  The demand (price) function in terms of x : P(x) = 12 - 0.025(x - 1500)

b) the marginal revenue function is \(MR(x) = dR(x)/dx = 12 - 0.05(x - 1500)\) The marginal revenue from the sales of 1800 T-shirts is -$3. This means that for each additional T-shirt sold after the 1800th, the revenue will decrease by $3 per T-shirt

To determine the demand (price) function, we need to find a relationship between the price of the T-shirts (P) and the number of T-shirts sold (x). We are given that for every $0.50 decrease in price, 20 more T-shirts will be sold.

Let's first find the decrease in price per T-shirt sold. If 20 more T-shirts are sold for every $0.50 decrease, then the decrease per T-shirt is $0.50/20 = $0.025. Now, we can set up the demand function. The base price is $12, and we decrease it by $0.025 for each additional T-shirt sold. So the demand function is:

P(x) = 12 - 0.025(x - 1500) To determine the marginal revenue function, we first need to find the total revenue function. Total revenue (R) is the product of the price (P) and the number of T-shirts sold (x):

R(x) = P(x) * x = (12 - 0.025(x - 1500)) * x Now we need to find the derivative of the total revenue function with respect to x, which will give us the marginal revenue function: MR(x) = dR(x)/dx = 12 - 0.05(x - 1500)

To determine the marginal revenue from the sales of 1800 T-shirts, we simply plug in x = 1800 into the marginal revenue function: MR(1800) = 12 - 0.05(1800 - 1500) = 12 - 0.05(300) = 12 - 15 = -$3

In Mathematics, the y-intercept of any graph such as a quadratic function, generally occur at the point where the value of "x" is equal to zero (x = 0).

In this scenario, the y-intercept of this quadratic function can be calculated as follows;

G(x) = -1/4(x²) + 3x + 37

G(0) = -1/4(0²) + 3(0) + 37

G(0) = 37.

The inequality that describes how many movies Parv can buy is: n ≤ 10.025

Let's denote the number of movies Parv wants to buy as n. We are given that each movie costs $3.99. To determine the inequality that describes how many movies Parv can buy, we need to consider the amount of money he has remaining after purchasing the pack of games.

Parv starts with a $50 gift card and spends $9.99 on a pack of games. The remaining amount on the gift card is $50 - $9.99 = $40.01.

Now, let's consider the cost of n movies. Each movie costs $3.99, so the total cost of n movies would be n * $3.99.

Since Parv wants to buy the movies using the remaining amount on his gift card, we can set up the inequality:

n * $3.99 ≤ $40.01

This inequality states that the total cost of n movies, represented by n * $3.99, must be less than or equal to the remaining amount on the gift card, which is $40.01.

Simplifying the inequality further, we have:

3.99n ≤ 40.01

Now, if we want to solve for n, we can divide both sides of the inequality by 3.99:

n ≤ 40.01 / 3.99

Calculating this value, we have:

n ≤ 10.02506265664

Therefore, the inequality that describes how many movies Parv can buy is:

n ≤ 10.025

This means that Parv can buy a maximum of 10 movies, as he cannot purchase a fractional part of a movie.
