In a random sample of 81 audited estate tax returns, it was determined that the mean amount of additional tax owed was $3415 with a standard deviation of $2501. Construct and interpret a 90% confidence interval for the mean additional amount of tax owed for estate tax returns.

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5

step-by-step explanation:

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
