Answer:
(c) 43.
Step-by-step explanation:
Given:
Margin of error (E) = 2
Sample variance
= 44
Confidence level = 95%
The z- value at 95% confidence level is 1.96.
The sample using the provided information can be calculated as:

Hence, the correct option is (c) 43.
Answer:
- asymptotes: x = -5, x = 5
- zero: x = 0
Step-by-step explanation:
The function of interest is ...

The asymptotes are found where the denominator is zero. It will be zero when either factor is zero, so at x = 5 and x = -5
__
The zeros are found where the numerator is zero. It will be zero for x = 0.
The asymptotes are x=-5, x=5; the zero is x=0.
Answer:
'16' is the answer.
Step-by-step explanation:
So, 6=x+2 divided by 3. In this case, we can multiply 6 and 3 which makes
18 = x+2. We substract 2 from 18 and the answer is 16. If you don't understand anything, you can ask by leaving a comment below. Thanks.
16+2 = 18/3 = 6
