Which is not equal to 60%?

The weight of water in the aquarium can be calculated by determining the volume of water and multiplying it by the weight of a cubic foot of water.

The given dimensions of the aquarium are 36 inches (length) by 24 inches (width) by 16 inches (height). The water level is at 12 inches. To calculate the volume of water, we multiply the length, width, and height of the water-filled portion, which is 36 inches by 24 inches by 12 inches.

Converting the volume to cubic feet (since the weight is given in pounds per cubic foot), we divide the volume by 12^3 (since 12 inches make up a foot) to get the volume in cubic feet.

Finally, we multiply the volume in cubic feet by the weight of a cubic foot of water, which is 62.4 pounds, to find the total weight of water in the aquarium.

Since J, P, and L are the midpoints of KH, HM, and MK, respectively, the values of x, y, and z are as follows;

x = 4.75.

y = 6.

z = 1.

In Geometry, the centroid theorem states that the centroid of a triangle is located at two-third (2/3) of the distance from the vertex to the midpoint of the (opposite) sides.

Generally speaking, the centroid of a triangle simply refers to the point where the three (3) medians of the triangle meet or intersect. By applying the centroid theorem to triangle KHM (ΔKHM);

Side HQ = 2/3(LH)

y = 2/3(3 + y)

3y = 2(3 + y)

3y = 6 + 2y

y = 6.

Side KQ = 2/3(KP)

7 = 2/3(7 + 2x - 6)

21 = 2(1 + 2x)

10.5 = 1 + 2x

2x = 9.5.

x = 4.75.

Side QM = 2/3(JM)

4 = 2/3(2z + 4)

12 = 2(2z + 4)

6 = 2z + 4

2z = 2.

(C) Regression analysis is the statistical method commonly used to estimate the level and trend in a time series by modeling the relationship between the data and independent variables.

Regression analysis is the statistical method used to estimate the level and trend in a time series. Time series data represents observations taken at different points in time and is commonly used to analyze trends and patterns over time.

Regression analysis allows us to model the relationship between a dependent variable (in this case, the time series data) and one or more independent variables (such as time or other relevant factors). By using regression analysis, we can identify the underlying trend in the time series and estimate its level.

The regression model captures the relationship between the dependent variable (the time series) and the independent variable(s) by fitting a line or curve that best represents the data. This line or curve helps to identify the overall trend and level of the time series.

While moving average, simulation method, covariance analysis, and correlation analysis are useful techniques in analyzing time series data, they are not specifically designed to estimate the level and trend in a time series. Therefore, (C) regression analysis is the most appropriate method for estimating the level and trend in a time series.

The exponential function for the graph is obtained as y = 3^x.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

Assume that the plot of a function is in the form -

y =ab^x

where the horizontal asymptote is the x-axis.

To find a, look for the coordinate where the curve crosses the y-axis.

In the plot, it is seen that this happens at (0,1).

So, the value of a = 1.

To find b, look for the coordinate where the curve crosses the vertical line at x = 1.

In the plot, it is seen that this happens at (1,3).

Then, b is the number divided by a -

b = 3/1 = 3.

This plot is the curve -

y = 3^x

Therefore, the exponential function is y = 3^x.

The sled is moving at approximately 9.38 m/s when you reach the other side of the pond.

To solve this problem, we can use the concept of work and energy. The work done on an object is equal to the force applied multiplied by the distance over which the force is applied. In this case, the work done is equal to the change in kinetic energy of the sled.

Let's break down the problem into two parts: when you're pulling with a constant force of 200 N and when you're pulling with a force increasing linearly from 200 N to 500 N.

First, let's calculate the work done during the first part of the motion, where the force is constant. The work done is given by:

Work = Force × Distance

Work = 200 N × (24 m/2)

Work = 200 N × 12 m

Work = 2400 N·m

The work done during this part is 2400 N·m. This work contributes to the sled's change in kinetic energy.

Next, let's calculate the work done during the second part of the motion, where the force is increasing linearly. The average force during this part is (200 N + 500 N) / 2 = 350 N. The distance covered during this part is 24 m/2 = 12 m. The work done is given by:

Work = Average Force × Distance

Work = 350 N × 12 m

Work = 4200 N·m

The total work done on the sled is the sum of the work done in both parts:

Total Work = Work (constant force) + Work (linearly increasing force)

Total Work = 2400 N·m + 4200 N·m

Total Work = 6600 N·m

Now, we can equate the work done to the change in kinetic energy:

Total Work = Change in Kinetic Energy

6600 N·m = (1/2) × mass × (final velocity)^2

Here, the mass of the sled is 150 kg. We need to solve for the final velocity.

Rearranging the equation:

(final velocity)^2 = (2 × Total Work) / mass

(final velocity)^2 = (2 × 6600 N·m) / 150 kg

(final velocity)^2 = 88 N·m/kg

final velocity = √(88 N·m/kg)

final velocity ≈ 9.3808 m/s

Therefore, the sled is moving at approximately 9.38 m/s when you reach the other side of the pond.

Answer:

1. Andre wants to buy a bike that has a price tag of $125. What was the wholesale cost of this bike?    $ 96.15

2. If the bike is discounted by 20%, how much will Andre pay (before tax)?  

                        $ 100

                                       I hope this helped <33 !

The wholesale cost of the bikes was $96.15 and the price that Andre can buy it for after the discount is $100.

The cost of the bikes after the markup is $125. The markup was 30%. Assuming the wholesale price is x, the expression would be:

x + (x × 30%) = 125

x + 0.3x = 125

1.3x = 125

x = 125/1.3

x = $96.15

If Andre want to buy the bike at a discounted price of 20%, the price would be:

= Selling price x (1 - Discount rate)

= 125 x (1 - 20%)

= 125 x 0.8

= $100

In conclusion, the wholesale price was $96.15 and the amount Andre pays is $100.

Step-by-step explanation:

For this problem, you'll need two formulas:

Slope: y1 - y2/x1 - x2

Point Slope: y - y1 = m(x - x1)

First thing you need to use is the slope formula.

Plugging in your coordinates gives you:

\(\frac{-2-3}{4-2}\) = \(\frac{-5}{-2}\)

You can simplify this by getting rid of the negatives since two negatives make a positive.

Now to use the point slope formula.

For this formula, the slope we just found, \(\frac{5}{2}\), replaces the m, and for the x1 and y1, you use one of the original points(either (4,-2) or (2,3)).

I'll be using the point (2,3). Now plug everything in:

\(y-3=\frac{5}{2} (x-2)\)

First thing you should do is distribute the \(\frac{5}{2}\):

\(y-3=\frac{5}{2} x-5\)

Next thing to do is get the y by itself by adding 3 to both sides, which gives you your answer of:

\(y=\frac{5}{2} x-2\)

200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

The absolute difference between the predicted and actual values must be determined, added together, and divided by the total number of periods.

Forecasted values are as follows: 1,500 and 1,400

Values in actuality: 1,200 and 1,500

Absolute differences:

|1,500 - 1,200| = 300

|1,400 - 1,500| = 100

Now, we calculate the MAD:

MAD = (300 + 100) / 2 = 400 / 2 = 200

Therefore, 200 is the mean absolute deviation. Therefore, choice three (200) is the right one.

A sample size of 266 vacuum cleaners must be selected to be 97% confident that the margin of error will not exceed 40 hours.

To determine the sample size needed for this scenario, we can use the formula: n = (z^2 * s^2) / E^2

Where:
- n is the sample size
- z is the z-score associated with the confidence level (in this case, 97% confidence corresponds to a z-score of 2.17)
- s is the estimated standard deviation (300 hours)
- E is the desired margin of error (40 hours)

Plugging in these values, we get:
n = (2.17^2 * 300^2) / 40^2
n ≈ 137.7

Rounding up to the nearest whole number, we would need a sample size of 138 vacuum cleaners in order to be 97% confident that the margin of error will not exceed 40 hours.

To determine the required sample size for a given margin of error with 97% confidence, we can use the formula:

n = (Z * σ / E)^2

where n is the sample size, Z is the Z-score associated with the desired confidence level, σ is the standard deviation, and E is the margin of error.

For a 97% confidence level, the Z-score is approximately 2.17 (from a standard normal distribution table). Given the standard deviation (σ) of 300 hours and a margin of error (E) of 40 hours, we can plug these values into the formula:

n = (2.17 * 300 / 40)^2
n = (16.275)^2
n ≈ 265.16

Since the sample size must be a whole number, we'll round up to the nearest whole number to ensure the desired confidence level is achieved. Therefore, a sample size of 266 vacuum cleaners must be selected to be 97% confident that the margin of error will not exceed 40 hours.

Approximately 84% of people wait less than 55 minutes at the DMV.

To find the percentage of people who wait less than 55 minutes at the DMV, we need to calculate the area under the normal distribution curve to the left of 55 minutes.

We can use z-scores to determine this area. First, we calculate the z-score for 55 minutes using the formula:

z = (x - mean) / standard deviation

z = (55 - 40) / 15

z = 1

Next, we look up the corresponding area in the standard normal distribution table for a z-score of 1. The area to the left of 1 is approximately 0.8413.

Converting this to a percentage, we get 84.13%.

Based on the sample data and the hypothesis test, there is sufficient evidence to support the claim that the population mean μ is greater than 29 at the significance level of 0.05.

What is the mean and standard deviation?

The standard deviation is a summary measure of the differences of each observation from the mean. If the differences themselves were added up, the positive would exactly balance the negative and so their sum would be zero. Consequently, the squares of the differences are added.

To test the claim about the population mean μ at the level of significance α, we can perform a one-sample t-test.

Given:

Claim: μ > 29 (right-tailed test)

α = 0.05

σ = 1.2 (population standard deviation)

Sample statistics: x = 29.3 (sample mean), n = 50 (sample size)

We can follow these steps to conduct the hypothesis test:

Step 1: Formulate the null and alternative hypotheses.

The null hypothesis (H₀): μ ≤ 29

The alternative hypothesis (Hₐ): μ > 29

Step 2: Determine the significance level.

The significance level α is given as 0.05. This represents the maximum probability of rejecting the null hypothesis when it is actually true.

Step 3: Calculate the test statistic.

For a one-sample t-test, the test statistic is given by:

t = (x - μ) / (σ / √(n))

In this case, x = 29.3, μ = 29, σ = 1.2, and n = 50. Plugging in the values, we get:

t = (29.3 - 29) / (1.2 / √(50))

= 0.3 / (1.2 / 7.07)

= 0.3 / 0.17

≈ 1.76

Step 4: Determine the critical value.

Since it is a right-tailed test, we need to find the critical value that corresponds to the given significance level α and the degrees of freedom (df = n - 1).

Looking up the critical value in a t-table with df = 49 and α = 0.05, we find the critical value to be approximately 1.684.

Step 5: Make a decision and interpret the results.

If the test statistic (t-value) is greater than the critical value, we reject the null hypothesis; otherwise, we fail to reject the null hypothesis.

In this case, the calculated t-value is approximately 1.76, which is greater than the critical value of 1.684. Therefore, we reject the null hypothesis.

hence, Based on the sample data and the hypothesis test, there is sufficient evidence to support the claim that the population mean μ is greater than 29 at the significance level of 0.05.

the volume of the silo is approximately 11,657.88 cubic meters.

To find the volume of the silo, we need to calculate the volumes of the cylinder and the cone separately, and then add them together.

The radius of the base of the silo is half the diameter, so it's 10 meters / 2 = 5 meters.

The height of the cylinder is given as 27 meters. Since the height of the cone is half the height of the cylinder, the height of the cone is 27 meters / 2 = 13.5 meters.

The volume of a cylinder is calculated using the formula:

Volume of Cylinder = π * radius^2 * height

Plugging in the values, we get:

Volume of Cylinder = π * 5^2 * 27 = 3375π cubic meters (approximately 10,598.07 cubic meters)

The volume of a cone is calculated using the formula:

Volume of Cone = (1/3) * π * radius^2 * height

Plugging in the values, we get:

Volume of Cone = (1/3) * π * 5^2 * 13.5 = 337.5π cubic meters (approximately 1059.81 cubic meters)

Adding the volumes of the cylinder and the cone, we get:

Volume of Silo = 3375π + 337.5π = 3712.5π cubic meters (approximately 11,657.88 cubic meters)
