Question:
22. What is the value of x if the mean of 30, 70, 110, X, and 200 is 110?
A 120
B. 130
C. 140
D. 150
Answer:
C. 140
Solution:
[tex]\sf Mean = \frac{sum \;of \;all \;numbers}{total \;count \;of \;numbers} \\\\\sf Mean = \frac{30+70+110+x+200}{5} \\\\\sf 110 = \frac{30+70+110+x+200}{5} \\\\\sf (5)(110) = 30+70+110+x+200\\\\\sf 550 = x + 410\\\\\sf x = 550 - 410\\\\\sf x = 140\\\\[/tex]
[tex]\therefore \;\large\boxed{\text{\sf The value of x is 140}}[/tex]
