The rule of the mean is

We will find the sum of the given numbers, then divide it by how many numbers

The given numbers are

4, 8, 14, 7, 0, 8, 2, 10, 3, 12

Their sum = 68

There are 10 numbers, then

To find the median we have to arrange the numbers from smallest to greatest, then take the middle number

0, 2, 3, 4, 7, 8, 8, 10, 12, 14

Since there are 10 numbers, then there are 2 numbers in the middle

Then we will find their average by adding them and dividing their sum by 2

The 2 middle numbers are the 5th and the 6th positions

The 2 middle numbers are 7 and 8

The answers are:

Sample mean = 6.8

The median = 7.5

Solution

- 40% of peole would vote for the mMath teacher out f the 750 people. This implies that the number of people tahat would vote for him is

- We are also told that there is a margin of error of 4%. This implies that the number of people that vote for the math teacher is either 4% more or 4% less than the 300 people

- 4% margin of error can be gotten as follows:

- Thus, the number of people that vote for him is 300 give or take 30 people

scal factor = 1.5

Step-by-step explanation:

the scale factor is the ratio of corresponding sides, image to original, that is

scale factor = [tex]\frac{C'D'}{CD}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex] = 1.5

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]

[tex]A(n) = 5169.06[/tex]

[tex]A(n) = 5169[/tex]

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

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.

The original statement is same as third statment and value of y is 27.

Writing the equation form for each statement -

Let the variable be represented as y.

1/3(30 - y) = 3/4

1/3×30 - y = 3/4

1/3×y - 30 = 3/4

1/3(30 - y) = 3/4

1/3(y - 30) = 3/4

Based on the interpretation of all the sentences in equation form, we find the statement 3 to be same as original statement. Solving the equation to get the value of y.

1/3(30 - y) = 3/4

10 - y/3 = 3/4

10 = 3/4 + y/3

10 = (3×4 + y×4)/12
