Hourly earnings of call center employees is not a discrete random variable.

The answer is C.

The continuous random variable is not a discrete random variable. Continuous random variables are variables that can take an infinite range of values within a specific range, such as time, length, and weight.

A discrete random variable is a random variable that can only take certain discrete values. A discrete random variable is defined as a variable that takes on a specific set of values or a range of values.

The number of births, number of fives, and number of applicants are all random variables that can only take certain discrete values within a particular range of possible values.

So, the answer is C. The hourly earnings of a call center employee in Boston is not a discrete random variable.

Function is a relation that the domain doesn't have the same/repetitive value in a single set.

Some set of relations have repetitive domain

For example, {(1,1),(1,2)} This is NOT a function.

But {(1,1),(2,1)} is a function because there are no repetitive domains.

Therefore the answers are first choice, second choice and fifth choice.

the control limits for the x-bar chart are 9.7439 minutes (LCL) and 11.0561 minutes (UCL), and the control limits for the R chart are 0 minutes (LCL) and 2.0529 minutes (UCL).

To compute the control limits for the x-bar (mean) and R (range) charts, we'll use the following formulas:

For the x-bar chart:

Upper Control Limit (UCL) for x-bar = x-double-bar + A2 * R-bar

Lower Control Limit (LCL) for x-bar = x-double-bar - A2 * R-bar

For the R chart:

Upper Control Limit (UCL) for R = D4 * R-bar

Lower Control Limit (LCL) for R = D3 * R-bar

Where:

x-double-bar = Overall mean of the sample means

R-bar = Overall mean of the sample ranges

A2 = Constant from the control chart constants table

D4 = Constant from the control chart constants table

D3 = Constant from the control chart constants table

For sample sizes of 4, the control chart constants are as follows:

A2 = 0.729

D4 = 2.281

D3 = 0

Given the information you provided:

Overall mean (x-double-bar) = 10.4 minutes

Average range (R-bar) = 0.9 minutes

Let's calculate the control limits:

For the x-bar chart:

UCL for x-bar = 10.4 + 0.729 * 0.9

             = 10.4 + 0.6561

             = 11.0561 minutes

LCL for x-bar = 10.4 - 0.729 * 0.9

             = 10.4 - 0.6561

             = 9.7439 minutes

For the R chart:

UCL for R = 2.281 * 0.9

         = 2.0529 minutes

LCL for R = 0

Answer:

2/5

Step-by-step explanation:

there are 5 lines starting at point 1 and ending at 2. point c is on the second line which makes it 2/5ths

The position of C on the number line below is 7/5 or 1 2/5.

The number line is a horizontal line where all the integers are placed at equal intervals. The number line is extended to infinity on both sides.

Also, the line segment between two integers also divided into subparts to represent the rational number.

here given in the number line there are two integers 1 and 2 in which point C is situated.

The line segment between 1 and 2 is divided into 5 parts.

every subpart in line segment between 1 and 2 will be= the length of the subpart / total number of division

= (2-1)/5= 1/5

C point is present at a distance of 2 subparts from integer 1.

So the position of C will be = 1+(2)(1/5)= 1+(2/5)= 7/5 or 1 2/5

Therefore The position of C on the number line below is 7/5 or 1 2/5.

Using the method of shells to find the volume of the donut created when the circle x² + y² = 4 is 32π².

The volume of a sphere represents its capacity. It is the space that the sphere occupies. The volume of a sphere is expressed in cubic units such as m3, cm3, in3, and so on. The sphere has a circular and three-dimensional form. It has three axes that define its shape: the x-axis, the y-axis, and the z-axis. Football and basketball are two examples of spheres with a lot of volume.

We have circle equation ,

x²+y²=4

so y² = 4-x²

taking square root on both side we get,

y = ± \(\sqrt{(4-x^2)\)

After taking the integral for finding the value we get,

volume\(V = 2\pi\int-22(4 - x)2\sqrt{(4 - x^2)dx\)

= \(4\pi[4 \int-22 \sqrt{(4 - x2)}dx- \int{-22x\sqrt{(4 - x^2)}dx]\)

=4π(8π - 0)

= 32π²

Therefore, the volume of the Donut is 32π².

1st integral is area of half of circle of radius 2; 2nd integral is 0 as integral of odd function in symmetric limits.

= \(\sqrt4 - x^2 - (- \sqrt4 - x^2)\)

= \(2\sqrt{4}\)

So after putting the limits we get the integral value as \(2\sqrt{4}\) .

Answer:

210 is the answerrrrrrrrrr

The measure of ∠A is 37 degrees, ∠B is 90 degrees and ∠C is 53 degrees in the triangle ABC.

Let us find ∠A by using sine function.

We know that sine function is a ratio of opposite side and hypotenuse.

The opposite side of ∠A is BC, which is 21.

The hypotenuse side of ∠A is AC, which is 35.

Sin∠A =21/35

Sin∠A =0.6

∠A =Sin⁻¹(0.6)

∠A =36.87 degrees.

∠B is 90 degrees.

By angle sum property the sum of three angles is 180 degrees in triangle.

∠A+∠B+∠C=180

37+90+∠C=180

127+∠C=180

Subtract 127 from both sides:

∠C=180-127

∠C=53 degrees.

Hey there! :)

Answer:

SA = 144 cm².

Step-by-step explanation:

Find the surface area by calculating the areas of each of the lateral sides and bases:

In this instance, the bases are triangles, so the formula A = 1/2(bh) will be used:

Bases:

A = 1/2(bh)

A = 1/2(4·3)

A = 1/2(12)

A = 6 cm².

There are two bases, so:

6 × 2 = 12 cm²

Find the areas of the lateral sides using A = l × w:

5 × 11 = 55 cm²

4 × 11 = 44 cm²

3 × 11 = 33 cm²

Add up all of the areas:

12 + 55 + 44 + 33 = 144 cm².

Answer:

144 cm^2

Step-by-step explanation:

So, first find the area of the triangle. To find that you need to use the formula A = bh ÷ 2 (Area = base x height ÷ 2)

A = (4)(3) ÷ 2

A of triangle = 6

Since there are 2 triangles, you need to multiply the area by 2, which equals 12.

To find the area of the rectangles, you need to use the formula A = lw (Area = length x width)

For the first rectangle,

A = 11 x 5

A = 55

For the second rectangle,

A = 4 x 11

A = 44

For the third rectangle,

A = 3 x 11

A = 33

Now, you need to add the areas of the triangles and rectangles together to get your surface area.

12 + 55 + 44 + 33 = 144cm^2

So, the surface area of the triangular prism is 144 cm^2.

The correct answer is the line crosses the z-axis at the point (0, 0, -9/2).

To find the equation of the plane that contains the points (-1, -1, -4), (1, 5, 8), and (-6, -3, -2), we can use the concept of linear algebra. A plane can be represented by an equation of the form:

ax + by + cz = d

where (x, y, z) are the coordinates of a point on the plane, and a, b, c, and d are constants.

To find the values of a, b, c, and d, we can use the three given points. Let's substitute the coordinates of each point into the equation and form a system of equations:

Equation 1: (-1)a + (-1)b + (-4)c = d

Equation 2: (1)a + (5)b + (8)c = d

Equation 3: (-6)a + (-3)b + (-2)c = d

To solve this system, we can set up an augmented matrix:

 | -1  -1  -4  | d |

 |  1   5   8  | d |

 | -6  -3  -2  | d |

We can row reduce this matrix to solve for the values of a, b, c, and d. Performing the row reduction, we obtain the following matrix:

 | 1   0   0  | -9 |

 | 0   1   0  |  5 |

 | 0   0   1  |  2 |From this row-reduced form, we can determine that a = -9, b = 5, c = 2, and d = -9.

Therefore, the equation of the plane is:

-9x + 5y + 2z = -9

To find where the line crosses the z-axis, we need to determine the point of intersection between the line and the z-axis. Since the z-axis is defined by x = 0 and y = 0, we can substitute these values into the equation of the plane:

-9(0) + 5(0) + 2z = -9

2z = -9

z = -9/2

Therefore, the line crosses the z-axis at the point (0, 0, -9/2).

Answer:

Mean =          15.83 hours

Median =  17 hours

Step-by-step explanation:

The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.

Once this is done, we have the responses as

responses: 9. 14, 16, 18, 19, 19

The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.

this is \(9 +14 + 19 + 18 + 16 + 14 + 19/ 6= 95/6 = 15.83\)

The mean of the distribution is 15.83 hours

The median is obtained by picking out the middle number of the distribution.  However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2

= (16 + 18 )/2 = 34/2 = 17

Answer:

(a) The average television hours for the six students in the previous week    was 15.83 Hours.

(b) The median number of hours would be 17 Hours

Step-by-step explanation:

Mean

The mean of a group of numbers is the average of the numbers. The mean can be gotten with the expression in equation 1.

Mean = Σx / n ...............1

Where Σx is the sum of the numbers

n is the number of values

Substituting our values into equation 1 we have;

Mean = (19+9+18+ 16+14+19) ÷ 6

Mean = 95 ÷ 6

= 15.83 Hours

Therefore the average television hours for the six students in the previous week were 15.83 Hours.

The median of a group of numbers is the middle term of the numbers when arranged in ascending or descending order.

Given the television hours of the six students, we have;

19, 9, 18, 16, 14, 19

We arrange the numbers in ascending order from the smallest to the biggest;

9, 14, 16, 18, 19, 19

Since the number of value is even the median would be obtained by finding the mean of the two middle terms.

From our arranged data, 9, 14, 16, 18, 19, 19

the two middle numbers are 16, 18

Therefore the mean would be

(16+18) /2

=34/2

= 17 hours

Thus the median number of hours would be 17 Hours

Given the set of numbers:

To be able to determine their correct ascending order, we must first make all the numbers into similar forms.

We are required to find a non-zero 2x2 matrix A such that A² = B, where B = [8].

Let A = [a, b, c, d] be a 2x2 matrix.

Then, A² = [a, b, c, d] x [a, b, c, d]

= [a² + bc, ab + bd, ac + cd, bc + d²].

We are given that B = [8].

Hence, A² = B implies that a² + bc = 8, ab + bd = 0, ac + cd = 0, and bc + d² = 8.

Since A is a non-zero matrix, it is not the zero matrix. Thus, at least one element of A is non-zero.

Since ab + bd = 0, either a = 0 or d = -b.

Let us assume that a is non-zero.

Since ac + cd = 0, we have c = -a(d/b).

Therefore, A = [2, 2, -2, 2] is a non-zero 2 x 2 matrix that satisfies A² = B, where B = [8].

The tangent line has the largest slope at the value(s) of x=0 where the derivative of the function y = -6 + 250x^3 - 3x^5 is maximized.

To find the value(s) of x where the tangent line has the largest slope for the given function y = -6 + 250x^3 - 3x^5, we need to determine the maximum of the derivative.

First, we find the derivative of the function: y' = 750x^2 - 15x^4. To find critical points, we set the derivative equal to zero: 750x^2 - 15x^4 = 0.

Factoring out x^2, we get x^2(750 - 15x^2) = 0. This equation has two solutions: x = 0 and x = √(750/15) = √50.

Next, we analyze the sign changes around these critical points to determine the behavior of the derivative. We can create a sign chart to evaluate the sign of the derivative in different intervals.

The intervals to consider are (-∞, 0), (0, √50), and (√50, +∞). After analyzing the sign chart, we find that the derivative is positive on (-∞, 0) and negative on (0, √50) and (√50, +∞).

Thus, the tangent line has the largest slope at x = 0 because the derivative changes from positive to negative at that point.
