PLEASE RESPOND QUIZ TOMORROW: Finding Value of X Using Central Tendencies

Question

Find X for all problems:

 

1. Mean is 4; 5,1,6,3,4,x

 

2. Median is 28; 21, 24, x, 30, 30, 32

 

3. Mean is -0.35; 2.25, -3.75, -1.25, 3.5, x

 

Thank you so much! Please respond ASAP

Answer 1

I'll do the first one the rest are done in the same way:

 

Given that the mean is 4 so 4=(5+1+6+3+4+x)/6, 24=19+x, so x=5

 

Hope this helps
