Question

if the mean of x,x + 2,x + 4, x + 6,x+ 8 is 24, find x

Answer 1

X+x+2+x+4+x+6+x+8=24
5x+20=24
5x=24-20=4
5x=4
x=4/5

Answer 2

Answer:x = 20

Step-by-step explanation:

• mean = sum of all observation / total number of observation  
• mean = 24                                          
• 24 = x , x+2 ,x+4 ,x+6 ,x+8/5                                
• 24 =5x + 20/ 5
• 24 x 5 = 5x + 20
• 120= 5x + 20
• 120 - 20 = 5x
• 100 = 5x
• x = 100 / 5
• x = 20
