The mean of five numbers is 8. If one of the five numbers is removed, the mean becomes 9. What is the value of the number that w
mestny [16]

Using the mean concept, it is found that the value of the number that was removed was of 4.

<h3>What is the mean?</h3>

The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

The mean of five numbers is 8, hence, the sum of the numbers is given by:

S = 5 x 8 = 40.

If one of the five numbers is removed, the mean becomes 9, hence, the sum of the four numbers is given by:

S = 4 x 9 = 36.

The difference is:

40 - 36 = 4.

Hence, the value of the number that was removed was of 4.

Determine if each fraction is a terminating decimal or a repeating decimal. Write each fraction in the correct box.
Alja [10]
-7/9 is repeating
42/50 is terminating
-1/125 is terminating
-77/600 is repeating
179/200 is terminating
5/11 is terminating

The way to figure this out is just by dividing the Numerator (top number) by the denomiter (bottom number)

Write 2350 million in standard form
AleksAgata [21]

we know that

<u>Standard Form</u> is also known as Scientific Notation, is a method of writing numbers that accommodates value excessively large or small to be suitably written in Standard Decimal Notation

in this problem we have

2,350\ million

Remember that

1\ million=1,000,000

so

2,350\ million=2,350*1,000,000=2,350,000,000

<u>convert to standard form </u>

2,350,000,000=2.35*10^{9}

therefore

<u>the answer is</u>

2.35*10^{9}

- There are 10 number one one the right side of the equation

Equation

                   3x + 4 = 10

Solve for x

                   3x = 10 - 4

                   3x = 6

                     x = 6/3

                    x = 2
