The area of the triangular prism is 240 mm²

A triangular prism is a prism with three rectangular faces connecting its two congruent triangular faces. It consists of 5 faces, 6 edges, and vertices.

The sum of the areas of all the triangle's faces is the surface area. By using the net of a prim we can determine the area of the prism as given below. Here we calculate the individual parts of the net to get the total area.

Here we have

A right triangular prism and its net  

The area of the prism can be calculated by calculating the area of the 2 triangles and the areas of 3 rectangles in the given net

As we know Area of rectangle = Length × Width

Area of rectangle parts = [ 3 × 8 ] + [ 3 × 15 ] + [ 17 × 3 ]

= 24 mm² + 45 mm² + 51 mm²

= 120 mm²  

Area of triangle parts = 2 [ 1/2 (15 × 8) ]

= 120 mm²  

Total area of prism = 120 mm² + 120 mm² = 240 mm²

Therefore,

The area of the triangular prism is 240 mm²

$50 can purchase 40 sports drinks.

A purchase is the acquisition of goods or services in exchange for money or other forms of payment. It is a common transaction that takes place in everyday life and can range from small purchases such as buying groceries, to larger purchases such as buying a car or a house.

When making a purchase, a buyer typically identifies a need or desire for a particular product or service, and then selects a seller or retailer who offers the desired item. The buyer then pays the seller the agreed-upon price, either in cash, by credit card, or through other forms of payment.

Purchases can take place in a variety of settings, including physical stores, online marketplaces, and through person-to-person transactions. The process of making a purchase may involve comparing prices, negotiating with the seller, and evaluating the quality and features of the product or service being purchased.

In addition to individual purchases, businesses and organizations also make purchases to acquire the resources and materials needed to operate and grow. This can include purchasing raw materials, equipment, and services from suppliers, as well as acquiring other businesses through mergers and acquisitions.

Overall, purchases are an important aspect of economic activity and play a crucial role in the functioning of markets and the economy as a whole.

Let's start by finding the cost of one sports drink:

$29.99 / 24 = $1.25 per sports drink

To find how many sports drinks can be purchased for $50, we divide $50 by the cost of one sports drink:

$50 / $1.25 per sports drink = 40 sports drinks

Therefore, the n-th term of the sequence is 19 - 2n.

An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a constant value to the previous term. This constant value is called the common difference of the arithmetic sequence. For example, the sequence 2, 5, 8, 11, 14, ... is an arithmetic sequence with a common difference of 3, since each term after the first is obtained by adding 3 to the previous term.

The nth term of an arithmetic sequence can be expressed using the following formula:

an = a1 + (n - 1)d

where an is the nth term of the sequence, a1 is the first term, n is the number of the term, and d is the common difference.

The sum of the first n terms of an arithmetic sequence can also be calculated using the formula:

Sn = n/2(2a1 + (n - 1)d)

where Sn is the sum of the first n terms, a1 is the first term, n is the number of terms, and d is the common difference.

Here,

The first term of the sequence is 17 and the common difference between consecutive terms is -2 (i.e. subtracting 2 from the previous term to get the next term). So, we can write the n-th term of the sequence as:

a_n = 17 + (n-1)(-2)

To calculate the optimal bundle, you need to find the combination of goods or services that maximizes the consumer's utility while staying within their budget constraint.

The optimal bundle can be found by using the consumer's utility function and their budget constraint. The utility function specifies how much utility the consumer gets from consuming various quantities of the goods or services, while the budget constraint specifies the combinations of goods or services that the consumer can afford given their income and the prices of the goods or services.

To find the optimal bundle, follow these steps:

Write down the consumer's utility function, such as U(x, y) where x and y are the quantities of two goods.

Write down the consumer's budget constraint, such as P_x x + P_y y = I where P_x and P_y are the prices of the goods, I is the consumer's income, and x and y are the quantities of the two goods.

Find the marginal utility of each good by taking the partial derivative of the utility function with respect to each good. For example, the marginal utility of x is given by dU/dx.

Set the marginal utility per dollar spent on each good equal to each other, since the consumer should allocate their spending so that the marginal utility per dollar spent is the same for both goods. That is, set dU/dx / P_x = dU/dy / P_y.

Solve the resulting equations for the quantities of the goods that maximize the consumer's utility subject to their budget constraint.

The resulting combination of goods that solves the optimization problem is the consumer's optimal bundle. It represents the combination of goods that maximizes the consumer's utility given their budget constraint.

Answer:

y = 22x - 20

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 22 , then

y = 22x + c ← is the partial equation

to find c substitute (1, 2 ) into the partial equation

2 = 22(1) + c = 22 + c ( subtract 22 from both sides )

- 20 = c

y = 22x - 20 ← equation of line

There is a 42.3% chance that the Rangers will win a majority of their seven games against the Islanders, assuming their win percentage stays the same.

We can use the binomial distribution to calculate the probability of the Rangers winning a majority of their games against the Islanders, given their win percentage of 55.1%. Let's denote the probability of the Rangers winning a single game against the Islanders as p.

Since the Rangers and Islanders play seven games against each other, the number of games the Rangers win against the Islanders follows a binomial distribution with parameters n = 7 and p = 0.551.

To find the probability that the Rangers win a majority of these seven games, we need to sum the probabilities of all possible outcomes where they win four or more games. We can use the binomial probability formula to calculate each of these individual probabilities and then sum them up:

P(Rangers win 4 or more games) = P(Rangers win 4 games) + P(Rangers win 5 games) + P(Rangers win 6 games) + P(Rangers win 7 games)

[tex]= (7 choose 4) * 0.551^4 * (1 - 0.551)^3 + (7 choose 5) * 0.551 ^ 5 * (1 - 0.551)^2 + (7 choose 6) * 0.551^6 * (1 - 0.551) + (7 choose 7) * 0.551^7[/tex]

Using a binomial calculator or a spreadsheet, we can evaluate this expression and find that:

P(Rangers win a majority of their games against the Islanders) = 0.423

Therefore, there is a 42.3% chance that the Rangers will win a majority of their seven games against the Islanders, assuming their win percentage stays the same.

The Binomial distribution is a discrete probability distribution that describes the probability of obtaining a certain number of successes in a fixed number of independent trials, where each trial can have only two outcomes (e.g., success or failure).

The distribution is defined by two parameters: the number of trials n and the probability of success in each trial p. The distribution gives the probability of obtaining k successes in n trials, where k can range from 0 to n.

The formula for the probability mass function of the Binomial distribution is:

[tex]P(k) = (n choose k) * p^k * (1 - p)^n-k[/tex]

where (n choose k) is the binomial coefficient, which gives the number of ways to choose k items from a set of n items. The formula can be used to calculate the probability of obtaining k successes in n trials, given a fixed probability of success p.

The Binomial distribution is used in many areas of statistics, including quality control, epidemiology, and finance, among others. It is also a fundamental building block for more complex statistical models, such as the Poisson distribution and the normal distribution.
