How to find mean: add up all the numbers and  divide by how many numbers

19, 19, 20, 20, 20, 21, 22, 22, 22, 22, 23

(19+19+20+20+20+21+22+22+22+22+23)/11=230/11=20.9(rounded)

If the new mean is 22, sum of all the numbers is 22 times 12=264

Help me please i need your help
marishachu [46]

Answer:

\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: SOLUTION: \: \: \: \: (3x + 4)^{2}}}}}}}}}

Step-by-step explanation:

The given statement is;: 'I think of a number, multiply it by 3, add 4 & square the result.'

At first, let's take the unknown number as 'x' . (asked in the question).

So, the number we think about = x

Now, we need to multiply it by 3. So,

  • 3 * x = 3x

In the next part, we need to add 4 to it so,

  • 3x + 4

Now, by squaring the result, we'll get the expression as,

  • <u>(3x + 4)²</u>

<u>____________</u>

Hope it helps!
