Step-by-step explanation:
We need to do LCM in this case.
2_|_ 6,4,16
2 _|_ 3,2,8
_|_ 3, 1,4
It is not divisible further.
So, LCM is 2×2×3×4 = 48
<u>So, 48 is the answer.</u>
Hope it helps :)

So before we can decide which graph it is, we have to find the zeros (x-intercepts) of this graph. We can do this by setting y to 0.
Firstly, factor out 3x on the right side of the equation: 
Next, use the zero product property to solve y = 0:


So we know that the zeros of this equation are (4,0) and (0,0). Looking at the four graphs, the only graph that has a line crossing those 2 points is the first graph. Therefore, the graph of this equation is the first graph.
The square root of 98 is 9.899<span> so I think if it was rounded to the nearest tenth it would be 9.9</span>
Answer:
The 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is (0.472,0.766).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
In a sample of 42 water specimens taken from a construction site, 26 contained detectable levels of lead.
This means that 
95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is (0.472,0.766).
