The total profits made from the sales at their hot chocolate shop is 26.15 dollars .

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Raven and Tyler are selling their cups of hot chocolate for $2.25.

They sold 11 cups. They are also selling candy canes on the side for $0.75 and spent $7.50 on supplies that they will have to pay back to the bank.

Therefore, the profit they make in small cups can be calculated as:

The amount sold in small cups = 2.25 × 11 = 24.75 dollars

The amount sold in large cups = 22 × 1.50 = 33 dollars

Therefore,

The profits made = 36 - 9.85 = 26.15 dollars

Percent to the nearest whole number = 7%

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

Probability = (Number of possible outcomes)/(Total number of outcomes)

Total number of outcomes = 2 + 15 + 2 + 11 = 30

Number of possible outcomes = 2

Probability = 2/30 = 1/15 = 0.0666

Percent to the nearest whole number =  0.0666 *100 = 7%

The correct trigonometric substitution for evaluating integral ∫√(x² + 64) dx is option B. x = 8 tan θ.

To evaluate the integral ∫√(x² + 64) dx using trigonometric substitution, use the substitution x = 8 tan θ.

Let's go through the steps to see how this substitution leads us to the solution:

1. Substitute x = 8 tan θ.

This implies dx = 8 sec² θ dθ.

2. Substitute the expression for x and dx in the integral:

∫√(x² + 64) dx becomes ∫√((8 tan θ)² + 64) * 8 sec² θ dθ.

3. Simplify the expression:

∫√(64 tan² θ + 64) * 8 sec² θ dθ = ∫√(64(sec² θ - 1)) * 8 sec² θ dθ.

4. Further simplify:

∫√(64sec² θ - 64) * 8 sec² θ dθ = ∫√(64sec² θ) * 8 sec² θ dθ.

5. Simplify the expression inside the square root:

∫8sec θ * 8 sec² θ dθ = ∫64sec³ θ dθ.

6. Integrate with respect to θ:

∫64sec³ θ dθ = 64∫sec³ θ dθ.

Now, this integral can be evaluated using standard trigonometric integral identities or integration techniques. However, it's worth noting that the original integral did not involve the variable θ, so we would eventually need to convert the result back to x by substituting x = 8 tan θ.

The correct answer is B. x = 8 tan θ.

Step-by-step explanation:

The profit function is P(x) = -500.523x^2 + 600x - 200.

To find the profit function, P(x), we need to subtract the cost function, C(a), from the revenue function, R(x).

Given:

Cost function: C(a) = 500x^2 + 300

Revenue function: R(x) = -0.523x^2 + 600x - 200 + 300

Profit function, P(x), is obtained by subtracting the cost function from the revenue function:

P(x) = R(x) - C(a)

P(x) = (-0.523x^2 + 600x - 200 + 300) - (500x^2 + 300)

Simplifying the expression:

P(x) = -0.523x^2 + 600x - 200 + 300 - 500x^2 - 300

P(x) = -500x^2 - 0.523x^2 + 600x + 300 - 200 - 300

P(x) = -500x^2 - 0.523x^2 + 600x - 200

Combining like terms:

P(x) = (-500 - 0.523)x^2 + 600x - 200

Simplifying further:

P(x) = -500.523x^2 + 600x - 200

Step-by-step explanation:

First, find the z-score.

z = (x − μ) / σ

z = (6 − 7) / 1

z = -1

Use a chart, a calculator, or the empirical rule to find the probability.

Using the empirical rule:

P(Z < -1) = 0.5 − 0.34

P(Z < -1) = 0.16

The percentage is 16%

To calculate the share between two numbers, divide one variety by way of the opposite and multiply the end result by way of one hundred, e.g. (30 / 75) * 100. This indicates what percent the first number is of the second one, in the example - 30 is 40% of 75.

In mathematics, a percent is more than a few or a ratio expressed as a fragment of 100. It is regularly denoted using the percentage signal, "%", although the abbreviations "pct.", "pct" and from time to time "pc" also are used. A percentage is a dimensionless number; it has no unit of size.

First, discover the z-rating.

z = (x − μ) / σ

z = (6 − 7) / 1

z = -1

Use a chart, a calculator, or the empirical rule to discover the chance.

By applying the unitary method, counting 67 colonies on a plate with 1ml of the 1:1,000,000 dilution indicates that 67,000,000 bacteria were present in 1ml of the original sample.

The unitary method is a mathematical technique that involves finding a unit value and using it to solve problems. In this case, we need to determine the number of bacteria present in 1ml of the original sample.

The dilution factor represents the ratio of the volume of the original sample to the volume of the diluted sample. In this case, the dilution factor is 1:1,000,000, which means that 1ml of the original sample was diluted with 1,000,000ml of a diluent solution to obtain 1ml of the diluted sample. Therefore, the number of bacteria in the original sample is 1,000,000 times the number of bacteria in the diluted sample.

Now, let's use the colony count to determine the number of bacteria in the diluted sample. We are told that 67 colonies were counted on the plate with 1ml of the 1:1,000,000 dilution. This means that each colony represents the growth of a single bacterium in the diluted sample. Therefore, the number of bacteria in the diluted sample is 67.

Using the unitary method, we can now determine the number of bacteria in 1ml of the original sample. We know that the number of bacteria in the original sample is 1,000,000 times the number of bacteria in the diluted sample. Therefore:

Number of bacteria in original sample = Dilution factor x Number of bacteria in diluted sample

Number of bacteria in original sample = 1,000,000 x 67

Number of bacteria in original sample = 67,000,000

So, the answer is that 67,000,000 bacteria were present in 1ml of the original sample.

Step-by-step explanation:

it depends upon the area of the triwngle

Therefore, Coastal Cove will have a higher temperature at 3:00 pm.

Temperature is a measure of the degree of hotness or coldness of an object or a substance. It is a physical quantity that is measured using a thermometer, and is typically expressed in units such as degrees Celsius (°C) or Fahrenheit (°F), or in the Kelvin (K) scale.

Temperature is a result of the average kinetic energy of the molecules or particles in a substance. When molecules or particles have a high kinetic energy, they move faster and collide more frequently, resulting in a higher temperature. Conversely, when molecules or particles have a low kinetic energy, they move more slowly and collide less frequently, resulting in a lower temperature.

Temperature is an important property in many scientific and engineering fields, such as thermodynamics, meteorology, and materials science. It is also important in everyday life for tasks such as cooking, heating and cooling homes and buildings, and monitoring body temperature for health purposes.

Part A: To find an exponential function that approximates the data on the table, we can use the exponential regression function on a calculator or software. Here is one possible exponential function that fits the data:

\(g(x) = 2.331(1.102)^x\)

where x represents the number of hours since 6:00 am and g(x) represents the temperature in °F.

Part B: To compare the temperatures at 3:00 pm, we need to evaluate the temperature function for each town at x=9 (since 3:00 pm is 9 hours after 6:00 am).

For Coastal Cove:

\(f(9) = 84(1.01)^9\) ≈ 100.63°F

For Inland burgh:

\(g(9) = 2.331(1.102)^9\) ≈ 98.77°F

Therefore, Coastal Cove will have a higher temperature at 3:00 pm.

The area of the figure/geometric shape U will be 15 yard^2.

What are geometric shapes in mathematics?

In Mathematics, Geometric shapes are the figures which demonstrate the shape of the objects we see in our everyday life. In geometry, shapes are the forms of objects which have boundary lines, angles and surfaces. There are different types of 2d shapes and 3d shapes.

Shapes are also classified with respect to their regularity or uniformity. A regular shape is usually symmetrical such as a square, circle, etc. Irregular shapes are asymmetrical. They are also called freeform shapes or organic shapes. For example, the shape of a tree is irregular or organic.

In plane geometry, the two-dimensional shapes are flat shapes and closed figures such as circles, squares, rectangles, rhombus, etc.  In solid geometry, the three-dimensional shapes are cube, cuboid, cone, sphere and cylinder. We can observe all these shapes in our daily existence also. For example books (cuboid shape), glasses (cylindrical shape), traffic cones (conical shape) and so on.

Now

As the scale factor for similar shapes V and U is 5:1.

Then their area should also be in same ratio.

15% = 570

100% = w (for "whole package")

15w = 100 * 570

15w = 57000

w = 57000 / 15

w = 3800

85 = m (for "men)

15m = 570 * 85

15m = 48450

m = 48450 / 15

m = 3230
