Question

whats the missing value for /16?

Answer 1

Answer:

How to find missing value

Step-by-step explanation:

Given the Numbers

Add up the numbers you know. The problem states a mean of 58 with this set of numbers: 43, 57, 63, 52 and ​x​. Assign the missing number a value of “​x​.” So add 43, 57, 63 and 52 to get 215.

Setting Up the Equation

Set up your equation by adding 215 plus “​x​” (the missing number), divided by 5, the number of values given. Set that side of the equation equal to the mean, 58. So, your equation would look like this:

\frac{215+x}{5}=58  

5

215+x

​  

=58

Isolating "x"

Multiply each side by 5 since our goal is to get “​x​” by itself. This process cancels the 5 on the left side of the equation and gives you 290 on the right side (58 × 5). Now, your equation should look like this:

215+x = 290215+x=290

Solving for "x"

Subtract 215 from each side as you continue to work to get “​x​” alone. This cancels out the 215 on the left side of the equation and gives you 75 on the right side. Now, your equation should show that ​x​ = 75. Therefore, the missing number is 75.

Check the Answer

Check the missing number by adding all the numbers together and dividing by 5.

\frac{43+57+63+52+75}{5}=\frac{290}{5}= 58
