Don’t know if there’s much of an equation for it, but I guess the best way to write it out is 10 + x = -18. Then, you would subtract the 10 from both sides in order to isolate the x. So then you’re left with x = -28. So -28 is your answer.

Answer:
<h3>-9p²+6p+2/4p²</h3>
Step-by-step explanation:
Given the expression
(p ^ 2 + 6p + 2)/(4p ^ 2) - (10p ^ 2)/(4p ^ 2)
Find the LCM
The LCM = 4p²
[p²+6p+2 - (10p²)]/4p²
Expand
p²-10p²+6p+2/4p²
-9p²+6p+2/4p²
hence the required expression is -9p²+6p+2/4p²
Answer:
We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case would be:
Ha: p > 0.15
Step-by-step explanation:
Information given
n=250 represent the random sample taken
X=40 represent the number of people on the alumni mailing list
estimated proportion of people on the alumni mailing list
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to test
