-3(x + 2)2 + 4 = -8 what’s the answer

Answer:
x = 0
Step-by-step explanation:
First, multiply the -3 by two (<u>-3</u>(x + 2)<u>2</u> + 4 = -8) -- -6(x+2)+4 = -8.
Then, subtract 4 from both sides (-6(x+2)+<u>4</u> = -8) -- -6(x+2) = -12
After that, divide both sides by -6 (<u>-6</u>(x+2) = -8) --
Simplify -- x+2=2
Subtract 2 from both sides (x+<u>2</u>=2) -- x = 0
Hope this helped! Good luck with future math problems :)

Use the attached formula.
exp = [log (total / principal) / n*years]
where "n" is compounding periods per year
exp = [log (7,194.66 / 2,978.41) / (365*21)
exp = log ( <span> <span> <span> 2.4156042989 </span> </span> </span> ) / 7,665
exp = log ( <span> <span> 2.4156042989 </span> </span> ) / 7,665
exp = 0.38302579382 / 7,665
exp = <span> <span> <span> 0.00004997074935681670 </span> </span> </span>
rate = (10^exp -1)* n

rate = 4.2 %
Yes, it's just that easy. LOL

Answer:
The 25th percentile is 248.
The 70th percentile is 700.
Step-by-step explanation:
The pth percentile is a data value such that at least p% of the data-set is less-than or equal to this data value and at least (100-p)% of the data-set are more-than or equal to this data value.
Arrange the data set in ascending order as follows:
S = {75 , 157 , 224 , 248 , 271 , 381 , 472 , 495 , 586 , 676 , 700 , 723 , 743 , 767 , 1250}
The formula to compute the position of the pth percentile is:
Compute the 25th percentile as follows:
The 4th observation from the arranged data set is 248 .
Thus, the 25th percentile is 248.
Compute the 70th percentile as follows:
The 11th observation from the arranged data set is 700.
Thus, the 70th percentile is 700.
