Answer:
the chance that the population mean will either be less than $1,500 or above $2,100 is 10%
Step-by-step explanation:
We are 90% confident that the true population mean willl be between $1,500 and $2,100
This means that there is a 90% probability that the true population mean will be between $1,500 and $2,100.
So 100-90 = 10% probability that it is outside of this interval, that is, either be less than $1,500 or above $2,100.
So the correct answer is:
the chance that the population mean will either be less than $1,500 or above $2,100 is 10%

Answer:
f(-6) = 72
Step-by-step explanation:
Input -6 for x :
2(-6)²
Complete with P.E.M.D.A.S :
2(36)
then :
72
so therefore :
f(-6) = 72
or
f of x equals 72
64^x=16^x-1====> Make the bases the same
4^3(x)=4^2(x-1)=> Solve for x by bringing down the exponent without the base.
3(x)=2(x-1)=====> Distribute
3x=2x-2======> Now solve for x
3x = 2x-2
-2x -2x
x=-2
Therefore x is negative two
