A : all real numbers

Answer:

A. All real numbers.

Step-by-step explanation:

According to the given information the mean(MAD) of the data is = 16.

The mean is the average of a set of variables in mathematics and statistics. The mean can be calculated in a variety of ways, such as the simple arithmetic mean (add the numbers and divide the sum by the number of observations), geometric mean, and harmonic mean.

(13 ,14 ,14, 16, 16, 16, 16, 18, 18, 19)

adding the numbers together.

(13 + 14 + 14 + 16 + 16 + 16 + 16 + 18 + 18 + 19)

= 160.

Then divide it by the amount of numbers. Which is ten.

160 divided by 10 = 16.

—MAD—

Subtract each value from the mean.

(|13-16| + |14-16| + |14-16| + |16-16| + |16-16| +|16-16| + |16-16| + |18-16| + |18-16| + |19-16|)

Negative numbers are unimportant; everything should be positive.

(3 + 2 + 2 + 0 + 0 + 0 + 0 + 2 + 2 + 3)

= 16.

16 divided by 16 (amount of numbers).

MAD = 1

–IQR—

Separate both sides in half.

(|13 14 14 16 16| ,|16 16 18 18 19|)

Take the middle value of each group.

Group1.

|13 14 (14) 16 16|

This one is 14.

Group 2:

|16 16 (18) 18 19|

This one is 18.

Subtract (number from group 2) 18 from (number from group 1) 14.

18 - 14 = 4

IQR = 4.

An independent event is an event whose occurrence are random event. There is no relationship between picking a yellow highlighter and then a green highlighter.

Probability determines the chances that a random event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

Probability of  picking a yellow highlighter and then a green highlighter = (number of yellow highlighters / total number of highlighters) x = (number of green highlighters / total number of highlighters)

Answer:

just put out + from the question.

The area of the region inside both curves r = 9 sin(θ) and r = 9 cos(θ) is 11.56 square units.

It is defined as the mathematical calculation by which we can sum up all the smaller parts into a unit.

The curves are:

r = 9 sin(θ) and

r = 9 cos(θ)

On graphing the above curves:

From the graph:

A = (1/2)∫(9sin(θ))2dθ + (1/2)∫(9cos(θ)2dθ

The region is symmetrical about π/4,:

A = 81∫sin2(θ)dθ from 0 to π/4

After solving:

= 11.56 square unit

Thus, the area of the region inside both curves r = 9 sin(θ) and r = 9 cos(θ) is 11.56 square units.

The two situations are:

Situation 1: Test Scores in Two Classes

Suppose we have two classes, Class A and Class B, taking the same exam with the same difficulty level.

The students in Class A are known to have a consistent level of performance, with most students scoring around the class average. The students in Class B, on the other hand, have a wider range of performance, with some students performing significantly better or worse than the class average.

In this situation, both classes are taking the same exam, so the central tendency (mean) of the test scores in Class A and Class B might be similar. However, the variability (spread) of the test scores in Class B is higher due to the wider range of performance among the students.

Situation 2: Monthly Rainfall in Two Cities

Consider two cities, City X and City Y, located in the same region. They experience a similar climate and weather patterns.

Over the course of a year, both cities receive roughly the same amount of rainfall on average. However, City X experiences more consistent monthly rainfall, with each month receiving rainfall close to the yearly average. In contrast, City Y has more variable monthly rainfall, with some months experiencing much higher or lower rainfall than the yearly average.

In this situation, the central tendency (mean) of the monthly rainfall in both cities will be similar since they receive the same average rainfall over the year.

We can form the eq. for y,

→ 6x - y = 2

→ y = 6x - 2

Then the value of x will be,

→ -4x + 3y = 1

→ -4x + 3(6x - 2) = 1

→ -4x + 18x - 6 = 1

→ 14x = 1 + 6

→ x = 7/14

→ [ x = 1/2 ]

Hence, the value of x is 1/2 (or) 0.5.

Now the value of y will be,

→ y = 6x - 2

→ y = 6(1/2) - 2

→ y = 3 - 2

→ [ y = 1 ]

Hence, the value of y is 1.

The location of Café 103 is (4.5, 4)

The given parameters are

From the question, we understand that:

Café 103 is collinear with and halfway between the Metrics School and the Angles Lab.

This means that Café 103 is at the midpoint

So, we have:

Café 103 = 0.5 * (x1 + x2, y1 + y2)

This gives

Café 103 = 0.5 * (2+ 7, 6 + 2)

Evaluate

Café 103 = (4.5, 4)

A histogram is a graph that shows the frequency of numerical data using rectangles.

A set of quantitative data with varying values may be shown as a list or a data display.

Center and spread are ways to describe data sets like this.

Center describes a typical value of a data point. Two measures of center are mean and median.

Spread describes the variation of the data. Two measures of spread are range and standard deviation.

The mean is useful for describing the center of data with similar values.

= 28.0 cents per ounce rounded to 1 decimal place
= 28 cents per ounce rounded to nearest cent

Step-by-step explanation:

[tex]\texttt{{Unit Price} = \ensuremath{\dfrac{\texttt{Total Price}}{\texttt{Quantity}}} }[/tex]

Here
Total Price = $3.98
Quantity = 14.2 ounce

By isolating the variable, we will see that the solution of the linear equation is v = -9

Here we have the following linear equation:

v/9 - 7 = -8

Where we can see that the variable is v. To solve this, we need to perform operations in both sides of the linear equation in a way such that the variable is isolated in one of the sides.

Adding 7 in both sides we get:

v/9 - 7 + 7 = -8 + 7

v/9 = -1

Now we multiply both sides by 9:

(v/9)*9 = -1*9 = -9

v = -9

We conclude that the solution of the linear equation is v = -9.

The dimensions of the fence that will maximize the area are-

Multiply the width by the height of a rectangle to find its area. If we know the lengths of two sides of a rectangle, we can calculate the height and width.

Now, as per the question;

Let 'L'  be the length and,

'W' width of the rectangular

Also, let the river is running along L.

Perimeter to be covered by fence:

P = L + 2W

2700 = L + 2W

Thus, L= 2700 - 2W

Substitute the value of L in the area

Area, A= LW

A = (2700 - 2W)W

A = 2700W - 2W²

This is a quadratic equation;

Now, the vertex of the rectangular with the greatest area will have the greatest width.

(W,A), where W= -b/2a where b = 2700 and a = -2

Solve for W,

W = -2700/2×(-2)

   = -2700/-4

W = 675 ft.

Substitute the value of W in L to find it.

L= 2700 - 2W

 = 2700 - 2×675

L = 1350 ft

Thus, the maximum area will become;

Maximum area A = 1350 × 675

Maximum area A = 911250 sq. ft

Therefore, the maximum area is found to be 911250 sq. ft
