Answer: $532,000

Step-by-step explanation:

If the company is making $140,000 and they get 20% each year, we just multiply it by 20%, or 0.20, and get $28,000. So, we would multiply that by 14, the years the company operated, and then add it to the original $140,000.

28,000 x 14 = 392,000

392,000 + 140,000 = 532,000

So, over the course of 14 years, the company made a profit of $532,000.

Answer:

Equation for x:    3x - 6 = \(\frac{2x - 1 + 25}{2}\)

x = 9

CD = 17

GH = 21

Step-by-step explanation:

The midsegment formula for a trapezoid is

GH = \(\frac{CD + FE}{2}\)

3x - 6 = \(\frac{2x - 1 + 25}{2}\)

6x - 12 = 2x + 24

4x = 36

x = 9

CD = 2x - 1 = 2(9) - 1 = 18 - 1 = 17

GH = 3x - 6 = 3(9) - 6 = 3 = 27 - 6 = 21

The formula 3x-y=5 is a linear function.

We must first examine the slope of the original function in order to determine the equation of parallel lines. We are also given the other function's intercept in this issue.

The function's slope-intercept form is y=3x-5.

In order to locate the parallel line that corresponds to the point (0,-7)

Parallel lines are those that share the same slope but have different y-intercepts, as you may have seen.

As a result, we must put in the point to solve for the y-intercept.

Thus,

y = 3x + b

-7 = 3(0) + b

-7 = b

b = -7

Thus the equation of a parallel line is y = 3x - 7

Answer:

The volume of a cylinder:

\(V \approx 2035.75\) \(ft^3\)

Step-by-step explanation:

-To find the volume of a cylinder, you first need the formula:

\(V = \pi (\frac{d}{2})^2 h\)

\(d =\) diameter

\(h =\) height

-Use the following diameter and height for the formula:

\(V = \pi (\frac{18}{2})^2 8\)

-Then, you solve:

\(V = \pi (\frac{18}{2})^2 8\)

\(V = \pi \times (\frac{18}{2})^2 \times 8\)

\(V = \pi \times (9)^2 \times 8\)

\(V = \pi \times 81 \times 8\)

\(V = \pi \times 648\)

\(V = 648\pi \approx 2035.752\)

-Since the hundredth place is 2, It cannot be rounded to the nearest hundredths place, so it would be:

\(V \approx 2035.75\) \(ft^3\)

Step-by-step explanation:

none of the provided options (a, b, c, d) appear to be accurate or close to the minimum space required.

To determine the minimum space required for a male restroom design with the given plumbing requirements, we need to consider the minimum space required for water closets and lavatories.

The minimum space required for water closets is typically around 30-36 inches per unit, and for lavatories, it is around 24-30 inches per unit.

Since the design requires a minimum of 12 water closets and 13 lavatories, we can estimate the minimum space required as follows:

Minimum space required for water closets = 12 water closets * 30 inches = 360 inches

Minimum space required for lavatories = 13 lavatories * 24 inches = 312 inches

Adding these two values together, we get a total minimum space requirement of 672 inches.

Among the given options, the closest value to 672 inches is option d) 249. However, this value seems significantly lower than the expected minimum space requirement.

This shows that they read less frequently than 95.7% of their classmates in the same grade level.

In statistics, a percentile is a metric that is used to express where one observation stands in relation to a larger group of data. It displays the proportion of data points that fall under a given value. For instance, if a student achieves a score in the 90th percentile on a standardised test, it signifies that they outperformed 90% of their peers who also took the test. As an alternative, if a child is taller than 25% of children their age and shorter than 75%, their height is in the 25th percentile for their age.

given

We must first compute the z-score using the following formula to determine the percentile of the child's reading proficiency.

z = (x - μ) / σ

where x represents the child's reading rate, represents the grade-level mean reading rate, and represents the standard deviation.

Inputting the values provided yields:

z = (46.2 - 85) / 22

z = -1.727

We can calculate or use a conventional normal distribution table to obtain the value of 0.0428 for the region to the left of z = -1.727. The child's reading rate is at the 4.28th percentile according to this statistic.

As a result, the child's reading proficiency is 4.3 percentile (rounded to one decimal place).

This shows that they read less frequently than 95.7% of their classmates in the same grade level.

Answer:

They will be 5 miles apart in 1 hour

Step-by-step explanation:

Here, we want to calculate the time it will take for the two ferries to be 5 miles apart

Mathematically; distance = speed * time

Let the number of hours be x

In x hours, the cat will have traveled 34 * x = 34x miles

In x hours, the Bird will have traveled 29 * x = 29x miles

So;

34x - 29x = 5

5x = 5

x = 5/5

The volume of the sphere is given by the situation V = 147.456π m³

A sphere is balanced, and round in shape. It is a three-layered strong, that has generally its surface focuses at equivalent good ways from the middle. It has surface area and volume in light of its radius. It has no faces, corners, or edges.

The Surface Area of a Sphere = 4πr²

The Volume of a Sphere

= ( 4/3 ) πr³

where r = radius of the sphere

Given information,

Let the volume of the sphere be addressed as V

Presently, the condition will be

Let the radius of the sphere be r

The worth of r = ( 4 8/10 ) m

In this way, the radius of the sphere = 4.8 m

Presently , Volume of a Sphere = ( 4/3 ) πr³

Subbing the qualities in the situation, we get

Volume of Sphere V = ( 4/3 ) π ( 4.8 )³

On improving on the situation, we get

Volume of Sphere V = ( 4/3 ) π ( 110.592 )

On additional improvement, we get

Volume of Sphere V = 147.456π m³

In the question, the independence assumption may have been violated, while the Nearly Normal Condition is likely justified. Therefore, the use of the Student-t model for inference may be unreliable.

a) In order to perform a hypothesis test on the claim made by the diet guide, we need to assess the assumptions and conditions required for reliable inference. The independence assumption states that the observations are independent of each other. In this case, it is not explicitly mentioned whether the yogurt samples were independent or not. If the samples were obtained from the same batch or were not randomly selected, the independence assumption could be violated.

Regarding the Nearly Normal Condition, which assumes that the population of interest follows a nearly normal distribution, it is reasonable to assume that the distribution of calorie counts in vanilla yogurt is approximately normal. However, since we do not have information about the population distribution, we cannot definitively justify this condition.

b) The appropriate hypotheses for testing the claim made by the diet guide would be:

H0: The average calories per serving of vanilla yogurt is 120.

HA: The average calories per serving of vanilla yogurt is not equal to 120.

To test these hypotheses, we can use a t-test for a single sample. The test statistic (t) can be calculated by taking the mean of the sample calorie counts and subtracting the claimed average (120), divided by the standard deviation of the sample mean. The p-value can then be determined using the t-distribution and the degrees of freedom associated with the sample.

Without the actual sample mean and standard deviation, it is not possible to provide the specific test statistic and p-value for this scenario. These values need to be calculated using the given data (calorie counts) in order to draw a conclusion about the claim made by the diet guide.
