Answer:
90
Step-by-step explanation:
Yes!
- you applied the distributive property
- combined like terms
- and answered the rest right!
The Population mean is 3.3 and the Sample mean is 3.6, 3.6-3.3 is 0.3

<em>Subtract</em> 2/3x on both sides.

Combine 5/3x and -2/3x to get x.

Subtract 4 from both sides. <em>Any value</em> subtracted from zero results in its negative value.
