The grapefruit's volume is approximately 1097.4 cubic centimeters.

The volume of sphere is the capacity it has. It is the space occupied by the sphere. The volume of sphere is measured in cubic units, such as m3, cm3, in3, etc. The shape of the sphere is round and three-dimensional. It has three axes as x-axis, y-axis and z-axis which defines its shape.

To find the volume of a sphere, we can use the formula:

\(V = (4/3) * π * r^3\)

where V represents the volume and r represents the radius of the sphere.

In this case, Chase measured the radius of the grapefruit as 6.4 cm. Plugging this value into the formula, we have:

V = (4/3) * π * \((6.4 cm)^3\)

V = (4/3) * π * \((262.144 cm^3)\)

V ≈ \(1097.445 cm^3\)

Rounding this value to the nearest tenth, the grapefruit's volume is approximately 1097.4 cubic centimeters.

Answer:

Step-by-step explanation:

a) The rate of people leaving the health club, L(t), can be calculated as:

L(11) = 0.013(11)^2 - 0.25(11) + 8

b) To find the number of people, we integrate the net rate of change over the time interval:

Number of People at t=20 = Integral of (E(t) - L(t)) dt, from t=0 to t=20

c) This can be done by finding the critical points of the net rate of change and evaluating them to determine whether they correspond to maximum or minimum values.

To determine whether the number of people in the facility is increasing or decreasing at time t=11, we need to compare the rates of people entering and leaving the health club at that time.

a) At time t=11 hours:

The rate of people entering the health club, E(t), can be calculated as:

E(11) = -0.018(11)^2 + 11

Similarly, the rate of people leaving the health club, L(t), can be calculated as:

L(11) = 0.013(11)^2 - 0.25(11) + 8

By comparing the rates of people entering and leaving, we can determine if the number of people in the facility is increasing or decreasing. If E(t) is greater than L(t), the number of people is increasing; otherwise, it is decreasing.

b) To find the number of people in the health club at time t=20, we need to integrate the net rate of change of people over the time interval 0≤t≤20 hours.

The net rate of change of people can be calculated as:

Net Rate = E(t) - L(t)

To find the number of people, we integrate the net rate of change over the time interval:

Number of People at t=20 = Integral of (E(t) - L(t)) dt, from t=0 to t=20

c) To determine the time t at which the number of people in the health club is a maximum, we need to find the maximum value of the number of people over the interval 0≤t≤20.

This can be done by finding the critical points of the net rate of change and evaluating them to determine whether they correspond to maximum or minimum values.

Let's calculate these values and solve the problem.

Note: Since the calculations involve a series of mathematical steps, it would be best to perform them offline or using appropriate computational tools.

Answer: $40

Step-by-step explanation:

If the worth of the stamp is double that of its original price 3 years ago ($1.25), the current price of the stamp should be $2.50. If that doubles every 3 years the answer should look something like this:

3 years: $5 (2.50X2=5)

6 years: $10 (5X2=10)

9 years: $20 (10X2=20)

12 years $40 (20X2=40)

In 12 years the stamp will be worth $40.

The system can be written as a vector equation as [5, 1, -3] [x1, x2, x3]^T = [8, 0]^T and as a matrix equation as AX = B, where A = [5 1 -3; 0 2 4], X = [x1; x2; x3], and B = [8; 0].

To write the given system as a vector equation, we group the variables and the constants into vectors and write the equations in a matrix form. Thus, the system can be written as [5x1 + x2 - 3x3; 2x2 + 4x3] = [8; 0], which is a vector equation.

To write the system as a matrix equation, we can write the coefficients of the variables in a matrix A, the variables in a vector X, and the constants in a vector B. Thus, the system can be written as AX = B, where A = [5 1 -3; 0 2 4], X = [x1; x2; x3], and B = [8; 0].

We can then solve for X by finding the inverse of A and multiplying both sides of the equation by it.

Answer:

the grade point average​ (GPA) of the student is 2.27

If the​ Dean's list requires a GPA of 3.00 or​ greater,  the student did not make the Dean's list.

Step-by-step explanation:

Given that:

A student grade are as follows:

B    ---   3

F   ---   0

B   ----   3

B  ----- 3

C ------- 2

Those courses had the corresponding numbers of credit hours 4​, 2​, 1​, 2​, and 2.

The grading system assigns quality points to letter grades as​ follows:

A = 4; B=​3; C=​2; D=​1; F=0

The sample mean simply implies the sum of the products of the value and the weights divided by the total weights;

i.e

\(\overline x = \dfrac{\sum xf}{n }\)

\(\overline x = \dfrac{3(4)+0(2)+3(1)+3(2)+2(2)}{4+2+1+2+2 }\)

\(\overline x = \dfrac{12+0+3+6+4}{11 }\)

\(\overline x = \dfrac{25}{11 }\)

\(\overline x =\) 2.27

the grade point average​ (GPA) of the student is 2.27

If the​ Dean's list requires a GPA of 3.00 or​ greater,  the student did not make the Dean's list.

The minimum wage set by the government at $7.50 per hour does not result in a pay cut for unskilled workers, as it is below the equilibrium wage of $8.00 per hour.

The wage rate remains unchanged, and the labor market remains in balance.

The statement is false.

False.

The equilibrium wage in the market for unskilled labor is $8.00 per hour, which means that the market naturally sets the wage rate at this level, based on the forces of supply and demand.

The government then sets a minimum wage at $7.50 per hour.

Since the minimum wage is below the equilibrium wage, it does not directly impact the wage rate for unskilled workers.
The equilibrium wage represents the point at which the supply of labor (the number of workers willing to work at a given wage) equals the demand for labor (the number of workers that employers are willing to hire at a given wage).

In this case, both workers and employers are satisfied with the $8.00 per hour wage, and the labor market is balanced.
The government sets a minimum wage below the equilibrium wage, it essentially sets a wage floor that is not binding. Employers are still willing to pay the equilibrium wage of $8.00 per hour, and workers are still willing to accept this wage.

The wage for unskilled workers remains at $8.00 per hour, and there is no pay cut of 50 cents per hour.

The commission does grace owe her broker is = 41. 43 $ (Option(b) is correct)

Given data,

Grace wishes to buy a corporate bond with a par value =  $1,000

If grace’s broker charges her a commission = 4%

A market rate = 103.563

So,

We can write,

In Mathematics, face value is the actual value of the digit in a number.

The par value or the face value of the share is the price that one gets while issuing.              

So, par value is $1000              

A commission of 4 % is charged by the broker.

The market rate is $103.563,  

Then,

Commission becomes as per par value =  \(\frac{4}{100} *103.563\)

= 0.04 * 103.563

= 41.425

≅ 41. 43 $

Therefore,

The commission does grace owe her broker is = 41. 43 $ (Option(b) is correct)

The second graph with numbers till 50 is not the accurate representation of the quiz grades.. The solution is obtained by using the concept of frequency plot.

What is frequency plot?

A frequency plot is a graphic data analysis approach for condensing information about a variable's distribution. The response variable is split into intervals of the same size (or bins). For every bin, the response variable's frequency is determined.

The vertical axis represents frequencies or relative frequencies, and the horizontal axis represents the response variable in the frequency plot (i.e., the mid-point of each interval).

The first graph accurately represents the quiz grades as the graph ranges from 0 to 100 and the markings on it are made from 10 to 70.

The second graph is not the accurate representation of the quiz grades because the graph is ranging from 0 to 50 but the quiz grades are ranging from 10 to 70.

The third graph accurately represents the quiz grades as the graph ranges from 0 to 90 and the markings on it are made appropriately.

The fourth graph also accurately represents the quiz grades as the graph ranges from 0 to 80 and the markings on it are made accurately.

Hence, the second graph with numbers till 50 is not the accurate representation of the quiz grades.
