The data that represent a population is helpful when we have to find the information only about one field.

In the given question we have decide how well data represent a population.

The total group you want to make judgments about is referred to as a population. Data is a set of quantitive data which refers the population only in numbers. So the data is only helpful when we have to find the only in small amount and only one field.

Data collection from a large population is typically only simple when the population is small, approachable, and cooperative.

Example: Gathering information from a population

A high school administrator is looking for trends in the final exam results of all graduating seniors. They use the entire population dataset since they are only interested in applying their findings to the graduating seniors in this high school. So the data is useful.

Area of irregular shape is 41.13m².

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina. Area can be interpreted as the quantity of material with a specific thickness required to create a model of the shape or as the quantity of paint required to completely cover a surface in a single coat.

Given,

Area of irregular shape = Area of rectangle + Area of semicircle

Area of rectangle = Length × Breadth

Area of rectangle = 9 × 3

Area of rectangle = 27 m²

Area of semicircle:

1/2πr²

1/2 × 3.14 × 3²

14.13 m²

Area of irregular shape = 27 + 14.13

Area of irregular shape = 41.13

Area of irregular shape is 41.13m².

The total number of free throws shots Jason made was 6 and the total number of two point shots Jason made was 7.

First, let us understand the variables:

Any number, vector, matrix, function, its argument, set, or one of its elements can be specifically represented by a variable.

Let x and y be the quantity of shorts.

x is the number of attempts at the free throw line.

y is the quantity of two-point attempts.

According to the question, we have;

x + 2y = 20 ............equation 1

x + y = 13    ............equation 2

From equation 2 we can take out the value of x;

x = 13 - y     ............equation 3

substituting the value of x in equation 1, we will get;

(13 - y) + 2y = 20

13 - y + 2y = 20

13 + y = 20

y = 20 - 13

y = 7

putting the value of y in equation 3, we will get

x = 13 - 7

x = 6

Thus, the total number of free throws shots Jason made was 6 and the total number of two point shots Jason made was 7.

The fraction form of 8 1/6 is 49/8 as the definition of fraction says, "An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided".

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator. A fraction merely informs us of the number of parts that make up the whole. The slash that is written between the two numbers identifies a fraction. The numerator is the highest number, and the denominator is the lowest number. 1/2, for instance, is a fraction.

Here,

8 1/6=(6*8+1)/8

=49/8

According to the definition of a fraction, which states that it is "a number represented mathematically as a quotient, where the numerator and denominator are divided," the fraction form of 8 1/6 is 49/8.

Answer:

B is correct. The slope is -3/2.

Answer:D

Step-by-step explanation:

Answer:

(a.):  Company A:  3x + 30; Company B:  2x+85

(b.) Company B is cheaper as it would cost $245 for Mia to drive 80 miles

Step-by-step explanation:

The equations we need are linear and we can think of them as such.  x represents the slope (cost per mile) and the initial fee represents our y-intercept or constant (amount paid before Mia ever drives)

(a.):  Thus, for company A, we have y = 3x + 30 and for company B we have y = 2x + 85.

(b.) Since we know that Mia needs to drive 80 miles, we plug this into x for both companies and find which one is lower

Company A:  3(80) + 30 = $270

Company B: 2(80) + 85 = $245

Company B's price would be lower for Mia's needs.

The equation that represents the table, in slope-intercept form, is: y = -2x + 11.

The slope-intercept form of an equation that represents a line is expressed as y = mx + b, where:

Using two pairs of values from the table, (6, -1) and (9, -7):

Slope (m) = (-7 -(-1)) / (9 - 6)

Slope (m) = -6/3

Slope (m) = -2.

Find the y-intercept, b, by substituting m = -2 and (x, y) = (6, -1) into y = mx + b:

-1 = -2(6) + b

-1 = -12 + b

-1 + 12 = b

b = 11

To write the equation, substitute m = -2 and b = 11 into y = mx + b:

y = -2x + 11

x =  4 -√16-4x 2 x 3))/(2x2)

Calculate the product or quotient

Torren will have $5169 in the account at the beginning of year 8. Option A is correct.

The following formula can be used to calculate the compound interest.

[tex]A(n) = P(1 + r)^{(t- 1)}[/tex]

where,

A(n) denotes the final sum.

P stands for the initial deposit.

r denotes the interest rate (in decimal).

t denotes the time (in year).

The compound interest will be C.I = A - P in this case.

We are given in the question;

The account's initial deposit is $4500, and the term is 8 years.

As a result,

A = 4500 and

t = 8

As we all know, interest is compounded once a year.

We shall divide the interest rate in percentage form by 100 to convert it to decimal form.

r = 2% = 2/100

⇒r = 0.02

The given equation is

[tex]A(n) = 4500(1 + 0.02)^{(n- 1)}[/tex]

Substituting the given values in the above equation, we will get,

[tex]A(n) = 4500(1 + 0.02)^{(8- 1)}[/tex]

[tex]A(n) = 4500(1 + 0.02)^{7}[/tex]

[tex]A(n) = 4500 \times 1.14868[/tex]
