Answer:
The answer is C) -2 and 6
Step-by-step explanation:
x+4 / -3x^2 + 12x + 36
= x + 4 / -3 ( x^2 - 4x - 12)
= x - 4 / -3(x - 6)(x + 2)
the excluded values make the denominator = 0
so the answer is -2and 6
Answer:
I believe it is 8 and 75/100.
Step-by-step explanation:
Standard deviation= σ= 0.1
Confidence interval= 95%= 0.95
Significance level=α= 1-0.95= 0.05
α/2 = 0.025
At α/2 z( α/2 ) =1.960 [from statistic table]
Now,
the sample size at error of 0.02 is
0.02=z( α/2 )σ/√n
0.02=(1.960)*(0.1)/√n
5/49 = 1/√n
√n=49/5
n=96.04
n should be 96 or greater
