Calculate x if the mean of 30, x, 12, 40, and 10 is equal to x.​

Answers

Answer 1

Answer:

23

Step-by-step explanation:

Let the mean also is x

Mean = Sum of all observations / Total no of observations

x = 30 + 12 + 40 + 10 + x / 5

5x = 92 + x

4x = 92

x = 23

Therefore 23 is the mean and also one of the numbers.

Answer 2

The value of x such that mean of  30, x, 12, 40, and 10 is equal to x will be 23.

What is mean?

The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.

Mean = sum of data / Number of data

It is known that,

Mean = sum of data / Number of data

x = (30 + x + 12 + 40 + 10)/5

5x = x + 92

4x = 92

x = 23

Hence "The value of x such that mean of  30, x, 12, 40, and 10 is equal to x will be 23".

It is a sequence where the difference between each consecutive term is the same.

We have,

The common difference between successive terms in the sequence 2, 8, 14, 20, 26, ... is 6.

To see why, notice that each term in the sequence is obtained by adding 6 to the previous term.

For example, to get from 2 to 8, we add 6. To get from 8 to 14, we add another 6.

This pattern continues for each successive term in the sequence.

Answer:

She is not correct

Step-by-step explanation:

This is the answer because:

1) We know that an integer is either a negative or positive number which has no fractional components/ no relation to fractions.

2) This means that an integer should not be expressed in the x/y form, also known as the fraction form.

3) Integers should always be a whole number that is negative or positive. An integer should never be a "part" of a number.

can you help me estimate 102.3+4.7

Answers

Answer: 107

Step-by-step explanation:

102.3 can be rounded down to 102 (because the 3 at the end of the number is  less than 5)

4.7 can be rounded up to 5 (because the 7 at the end of the number is greater than 5).

102.3  → estimate = 102

    4.7 →  estimate =   5  

   estimated sum  = 107

Note that estimating the sum is NOT the same as simply adding the numbers and then rounding the sum.

Jordan's team gained 12 yards in the first play in the 2nd play they lost 8 yards witch expression could be used to describe the total yards gained by the team

Answers

Answer:

The expression is (x + 4) yards where x yards represent the initial amount of yards had by tre team

Step-by-step explanation:

In this question, we are told to write an expression which can be used to describe the total yard gained by the team.

Now, before we can write an expression showing the yard gained by the team, we need a variable that will represent the amount of yard they had initially.

Let us represent this by x yard.

By gaining 12 yards in the first play, total amount of yards now become x + 12 yards

Now in the second play, they lost 8 yards and this translates to (x + 12)-8 = (x + 4) yards
