The circumference of the circle is 78.5 cm

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident.

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre.

The diameter of the circle is calculated by calculating the diagonal of the rectangle.

d = √7² +24²

d = √625

d = 25 cm

therefore the diameter of the circle is 25 cm

The circumference of a circle is expressed as;

C = πd

C = 3.14 × 25

= 78.5 cm

Therefore the circumference of the circle is 78.5 cm.

The probability that their hospital stay is greater than 6 days is approximately 0.6985.

(a) To find the probability that their hospital stay is from 5 to 6 days, we need to calculate the z-scores for both values using the formula z = (x - μ) / σ, where x is the value, μ is the mean, and σ is the standard deviation.
For 5 days: z = (5 - 7.37) / 2.60 = -0.9
For 6 days: z = (6 - 7.37) / 2.60 = -0.52

Next, we need to find the corresponding probabilities using a z-table or a calculator. From the z-table, we find that the probability of z being less than -0.9 is 0.1841, and the probability of z being less than -0.52 is 0.3015.

To find the probability of the hospital stay being between 5 and 6 days, we subtract the probability of z being less than -0.9 from the probability of z being less than -0.52:
P(5 ≤ X ≤ 6) = P(X ≤ 6) - P(X ≤ 5)

= 0.3015 - 0.1841

= 0.1174
Therefore, the probability that their hospital stay is from 5 to 6 days is approximately 0.1174.

(b) To find the probability that their hospital stay is greater than 6 days, we need to find the probability of z being greater than -0.52.

From the z-table, we find that the probability of z being less than -0.52 is 0.3015.

Therefore, the probability that their hospital stay is greater than 6 days is approximately

1 - 0.3015 = 0.6985,

rounded to five decimal places.

The correct formula to calculate the number of tires, t, needed for c cars per day is t = c/4, which is option b).


The formula that shows how to calculate the number of tires, t, needed for c cars per day is option b) t = c/4.

To understand this formula, let's break it down step by step:

1. Each car needs four regular tires and one spare tire for the trunk. So, the total number of tires needed for one car is 4 + 1 = 5.

2. If we want to calculate the total number of tires needed for c cars, we can multiply the number of cars by the number of tires needed per car, which is 5. So, the formula becomes t = 5c.

3. However, we need to find the number of tires needed, which is represented by t. Since we have t on the left side of the equation, we can rearrange the formula by dividing both sides by 5: t/5 = c.

4. Now, we have the number of tires needed (t) expressed in terms of the number of cars (c), but we want to find the number of cars needed given the number of tires (t).


To do this, we can rearrange the formula again by dividing both sides by 4: t/4 = c/4.

Therefore, the correct formula to calculate the number of tires, t, needed for c cars per day is t = c/4, which is option b).

The price that maximizes revenue is p = 120.

The price that maximizes revenue, we need to find the value of price (p) that corresponds to the maximum value of revenue (R). Revenue is calculated by multiplying the quantity (q) sold by the price (p), so we can express revenue as R = p × q.

Given the demand function q = -5p + 1200, we can substitute this expression for q into the revenue equation:

R = p × q

R = p × (-5p + 1200)

To find the price that maximizes revenue, we can take the derivative of the revenue function with respect to price (p), set it equal to zero, and solve for p.

dR/dp = -10p + 1200 = 0

Solving this equation for p:

-10p + 1200 = 0

-10p = -1200

p = -1200 / -10

p = 120

Therefore, the price that maximizes revenue is p = 120.

The system that sought to ensure the availability of a subservient agricultural labor supply controlled by white people.

Slavery is the practice of forcing individuals to work without pay or freedom. Historically, it has been used as a means of exploiting people for economic gain, and it has been justified on the basis of race, ethnicity, religion, or social status.

In the transatlantic slave trade, which lasted from the 16th to the 19th century, millions of Africans were captured and forcibly transported across the Atlantic Ocean to the Americas, where they were sold into slavery. Slaves were treated as property and denied basic human rights, such as the right to freedom, education, and family.

The system that sought to ensure the availability of a subservient agricultural labor supply controlled by white people is known as "slavery." Slavery was a brutal and inhumane practice that existed in many parts of the world throughout history. In the United States, slavery was primarily used to support the Southern agricultural economy, with enslaved people being forced to work on plantations producing crops such as cotton, tobacco, and sugar cane. The abolition of slavery in the United States was a long and difficult struggle that culminated in the Civil War and the passage of the 13th Amendment to the US Constitution in 1865.

The measure of the angle ACB is 59°.

Step-by-step explanation:

Let be \(D\) the location of the center of circle and \(r\) is the radius of the figure, the triangles ACD and BCD are isosceles triangles, since \(AD = CD = BD = r\). And the measure of the angle C associated with each triangle are, respectively:

Triangle ACD

\(m\angle C = \frac{180^{\circ}-89^{\circ}}{2}\)

\(m\angle C = 45.5^{\circ}\)

Triangle BCD

\(m \angle C = \frac{180^{\circ}-153^{\circ}}{2}\)

\(m\angle C = 13.5^{\circ}\)

Lastly, the measure of the angle ACB is:

\(m\angle ACB = 45.5^{\circ} + 13.5^{\circ}\)

\(m\angle ACB = 59^{\circ}\)

The measure of the angle ACB is 59°.

The sample size necessary such that the margin of error of the estimate for a 90% confidence interval for the mean age of all residents is at most 3.4 years is 59.56.

What is a confidence interval?

An estimated range for an unknown parameter is known as a confidence interval. The 95% confidence level is the most popular, however other levels, such as 90% or 99%, are occasionally used when computing confidence intervals.

Here, we have

Given: A city official would like to estimate the mean age of all residents of Stuart. The standard deviation of the ages of all residents of Stuart is known to be 16 years.

σ = 16 ..Population SD

The margin of error, E = 3.4

c = 90% = 0.90 ...confidence level

a = 1 - c = 1 - 0.90 = 0.1

We have to find the confidence interval for the true mean coefficient of restitution.

We can easily find the confidence interval through the formula of margin of error.

Margin of error is the difference between the calculated values and the real values.

Margin of error=z*σ/\(\sqrt{n}\)

where z is the z value of p value,

σ is population mean or sample mean,

n is the sample size.

In our problem the sample size is 30.

z value for the p value of 0.99 is 2.576.

Margin of error=2.576*0.019/\(\sqrt{30}\)

=0.048944/5.4772
