Answer:
all real numbers.
Step-by-step explanation:
<em>gg</em>
<em>all </em><em>are </em><em>real </em><em>numbers</em>
i assume the line plot is the % difference, the original 95% vs 92% has a difference of 3%,
the 10 random values center around 3% and 3% has the most occurrences of the 10.
the average value for the 10 is 2.9%, so that is within .1 of the original 3%
so it should be significant, not sure what criteria you are supposed to use?
is there a p or z test involved?
Hope this helps!
The answer is x=2
Remember, first add/substract the like terms, in this case 6x-10x to get -4x. Then, add 8x to negative 8x to cancel it out and do the same thing to -4x. Do this with all your terms and you should get 4x=8. Then divide both sides by 4 to get x=2.
