Answer:
y= 8000x + 2000
Step-by-step explanation:
to find the formula we can use the points given in the question:
the slope:
to get the slope we can take the 2 points, (0,2000) and (2,18000) where x values are time and y values are bacteria
now using slope-intercept form we can get which gives a slope of 8000 meaning for each hour there are 8000 new bacteria
intercept:
since we start with 2000 bacteria we know this is the y intercept so when x is 0
formula:
y=8000x + 2000
Using the Central Limit Theorem, the percentage that is expected to be the closest to the actual percentage is:
A. The Tribune, at 68%.
<h3>What does the Central Limit Theorem state?</h3>It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean and standard error
, as long as
and
.
From this, a larger sample size leads to a smaller error estimate. Since the Tribune had the largest sample size, option A is correct.
