Answer:
4x^2 +16x +42 +92/(x -2)
Step-by-step explanation:
Synthetic division tells you the quotient is 4x^2 +16x +42 with a remainder of 92. To check this, we can multiply the quotient by the divisor and add the remainder:
(x -2)(4x^2 +16x +42) +92
= x(4x^2 +16x +42) -2(4x^2 +16x +42) +92
= 4x^3 +16x^2 +42x -8x^2 -32x -84 +92
= 4x^3 +8x^2 +10x +8 . . . . . the original dividend, as required
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
Given : Sample mean : hours
Standard deviation hours
Sample size : n=90, which is a large sample(n<30), so we use z-test.
Significance level:
Critical value :
Then , the confidence interval for population mean will be :-
Hence, the 90% confidence interval for the mean life of all light bulbs of this type. is
