Answer:

16 of the 33 plays none.

Step-by-step explanation:

From the list, we get that 18 students play football, 1 basketball, and 7 both.

What we need to do here is add up 18 and 1

then we subtract 19 by 7 to cancel out the people who play both

and then subtract the total number of 33 by 17,

which gives you 16.

The volume V of solid S is e - 1 cubic unit.

What is Volume?

Volume refers to the measure of three-dimensional space occupied by an object or a region. It quantifies the amount of space enclosed by the boundaries of an object or contained within a given region. In mathematical terms, volume is often calculated by integrating the cross-sectional areas of the object or region along a particular axis. Volume is typically expressed in cubic units, such as cubic meters (m^3) or cubic centimeters (cm^3). It is an essential concept in geometry, physics, engineering, and other scientific fields where the measurement of three-dimensional space is involved.

To find the volume of solid S, we need to integrate the areas of the cross sections perpendicular to the x-axis along the interval \([e, \infty).\)

The area of each square cross-section is equal to the square of the side length, which in this case is \(y = \sqrt{\ln(x)}.\)

Therefore, the volume V of solid S can be calculated as:

\(V = \int_{e}^{\infty} (\sqrt{\ln(x)})^2 dx\)

To evaluate this integral, we can simplify the expression:

\(V = \int_{e}^{\infty} \ln(x) dx\)

Using integration by parts, we let \(u = \ln(x)\)and dv = dx:

\(du = \frac{1}{x} dx\\v = x\)

Applying the integration by parts formula:

\(V = [uv] - \int v du= [x \ln(x)] - \int x \left(\frac{1}{x}\right) dx= x \ln(x) - \int dx= x \ln(x) - x + C\)

Evaluating the definite integral:

\(V = [x \ln(x) - x]_{e}^{\infty}= (\infty \cdot \ln(\infty) - \infty) - (e \cdot \ln(e) - e)= \infty - 0 - (1 - e)= e - 1\)

Therefore, the volume V of solid S is e - 1 cubic unit.

Answer: The first 3 options

Step-by-step explanation:

You have to make sure that the given variable would be able to equal -5. The  \(\geq\) sign in the second and third answer show that the variable could be equivalent to -5.

Answer:

g > -7, f ≤ -5 and g ≥ -5

Step-by-step explanation:

the < and > symbols mean less than and greater than respectively, but not including. Therefore -5 cannot be a valid solution if the range is (for example) g > -5. However, ≤ and ≥ mean less/greater than or equal to, so -5 would be a valid solution for g ≥ -5 (for example).

Step-by-step explanation:

The function represented by the f(x) =\(2(\frac{1}{2})^x\) is an exponential decay function

The function is  

f(x) =\(2(\frac{1}{2})^x\)

The function is defined as the expression that represents the relationship between one variable and another variable.

The function is in the form of

f(x) = a × \(b^x\)

Such functions are called exponential function

Here  

The value of a = 2

The value of b = 1/2

If the value of b > 1, the function is called exponential growth function.

If the value of b < 1, the function is called exponential decay function.

Here b < 1

Therefore it is exponential decay function

Hence, the function represented by the f(x) =\(2(\frac{1}{2})^x\) is an exponential decay function

The probability of getting a job with Globo Corp, given that you applied, can be calculated by multiplying the probability of getting an interview (66%) by the probability of getting the job, given that you had an interview (41%). The resulting probability is 27.06% or approximately 0.27.

Let's denote the event of getting an interview as A and the event of getting the job as B. We are interested in finding the probability of event B given that event A occurred, denoted as P(B|A).

According to the given information, P(A) = 0.66 (66% chance of getting an interview) and P(B|A) = 0.41 (41% chance of getting the job given an interview).

To calculate P(B), the probability of getting the job overall, we can use the formula:

P(B) = P(A) * P(B|A)

Substituting the values, we have P(B) = 0.66 * 0.41 = 0.2706.

Therefore, the probability of getting the job, given that you applied for a job with Globo Corp, is approximately 0.27 or 27.06%.

Answer:

A) both functions are linear

B) f(x) = 7446.4x + 178713.6 and f(x) = 11000x + 179000

C) House 2 will value $106894.4 more than house 1.

Step-by-step explanation:

A) Value Increase from year 1 to year 2:

House 1: 193,606.40 - 186,160 = 7446.4

House 2: 201,000 - 190,000 = 11000

Value Increase from year 2 to year 3:

House 1: 201,350.66 - 193,606.40 = 7744.26

House 2: 212,000 - 201,000 = 11000

This means that a constant increament in x variable gives a constant increament in both houses vales. Then, both functions are linear.

B) The slope is the same as the value increment from one year to the next one.

slope (m) of House 1: 7446.4

slope (m) of House 2: 11000

General formula of a line:

f(x) = mx+b

Replacing with a known point:

House 1

186,160 = 7446.4(1) + b

b = 186,160 - 7446.4 = 178713.6

equation: f(x) = 7446.4x + 178713.6

House 2

190,000 = 11000(1) + b

b = 190,000 - 11000 = 179000

equation: f(x) = 11000x + 179000

C) Replacing x = 30 into each equaiton:

Value of House 1 after 30 years

f(x) = 7446.4(30) + 178713.6 = 402105.6

Value of House 2 after 30 years

f(30) = 11000(30) + 179000 = 509000

Then, house 2 will value 509000 - 402105.6 = $106894.4 more than house 1.

The solution to the system of equations is x = 7 and y = -3

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

5x + 2y = 29

5x - 2y = 41

Add both equations

So, we have

10x = 70

Divide the equation by 10

So, we have

x = 7

Substitute x = 7 in 5x - 2y = 41

5 x 7 - 2y = 41

This gives

35 - 2y - 41

Evaluate

2y = -6

Divide by 2

y = -3

To find the number of jelly beans that fit in a 2001 Chevy Suburban, we first need to calculate the volume of the car's interior. The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the length of the Suburban is 219.3in, the width is 78.8in, and the height is 75.4in.

Using the formula V = lwh, we can calculate the volume:

V = 219.3in * 78.8in * 75.4in

Next, we need to find the volume of a single jelly bean. Since the question does not provide this information, we will assume a standard jelly bean size.

Once we have the volume of the car and the volume of a single jelly bean, we can divide the car's volume by the jelly bean's volume to find the number of jelly beans that fit.

The value of 14.3 km/L of gasoline corresponds to approximately 33.6 miles per gallon (mpg).

To convert the fuel efficiency from kilometers per liter (km/L) to miles per gallon (mpg), we need to apply a conversion factor. The conversion factor is based on the fact that 1 kilometer is approximately equal to 0.6214 miles and 1 liter is approximately equal to 0.2642 gallons.

Convert km/L to km/gallon

To do this, we divide the fuel efficiency in km/L (14.3 km/L) by the number of kilometers in a mile (0.6214 km/mile) to get the value in km/gallon.

14.3 km/L ÷ 0.6214 km/mile = 23.02 km/gallon

Convert km/gallon to miles per gallon (mpg)

Next, we convert the value in km/gallon to miles per gallon (mpg) by multiplying it with the number of kilometers in a mile (0.6214 miles/km).

23.02 km/gallon × 0.6214 miles/km = 14.3 miles per gallon (mpg)

Therefore, the value of 14.3 km/L of gasoline corresponds to approximately 33.6 miles per gallon (mpg).

The value of x, y and z in the rhombus are 9, 2 and -4.

A rhombus is a quadrilateral that has 4 sides congruent to each other. The sum of angles in a rhombus is 360 degrees.

Therefore, let's find the value of x, y and z in the rhombus as follows:

Hence,

10y + 3 = 23

10y = 23 - 3

10y = 20

y = 20 / 10

y = 2

Therefore,

3x - 4 = 23

3x = 23 + 4

3x = 27

x = 27 / 3

x = 9

-6z - 1 = 23

-6z = 23 + 1

-6z = 24

divide both sides by -6

z = 24 / -6

z = -4

To find the volume of a cone, we use the formula V = (1/3)πr²h or V = (1/3)π(d/2)²h, where r is the radius, d is the diameter, and h is the height of the cone.

Example 1: A cone with a height of 8 cm and a radius of 3 cm.

V = (1/3)π(3²)(8)
V = 24π
V ≈ 75.4 cm³

Example 2: A cone with a height of 12 cm and a diameter of 6 cm.

V = (1/3)π(6/2)²(12)
V = (1/3)π(3²)(12)
V = 36π
V ≈ 113.1 cm³

Example 3: A cone with a height of 5 cm and a diameter of 10 cm.

V = (1/3)π(10/2)²(5)
V = (1/3)π(5²)(5)
V = (1/3)π(25)(5)
V = 125/3π
V ≈ 130.9 cm³

Example 4: A cone with a height of 15 cm and a radius of 2.5 cm.

V = (1/3)π(2.5²)(15)
V = (1/3)π(6.25)(15)
V = (1/3)π(93.75)
