The answer is B because it is the middle of 16 and 24
This is simply a question about ratios. This ratio means that for every 1 cm on the map, there are 12 km in actuality. You can set this problem up in fractions:
1 cm 12 cm
-------- = ----------
12 km x
To solve for x, we cross-multiply, for the moment ignoring units. Remember, your answer will be in km.
1*x=12*12
x=144
If x=144, then for 12 cm, there are 144 km.
Answer: c. We are 95 percent confident that the proportion of people in the sample who think climate change is a problem is between 0.146 and 0.214.
Step-by-step explanation:
Interpretation for 95% confidence interval :
A person can be 95% confident that the true population parameter lies in it.
By considering the given information , we have
population parameter→ p (Proportion of people who think climate change )
95 percent confidence interval = (0.146, 0.214)
Interpretation : We can be 95% confident that the true population proportion of people who think climate change lies between 0.146 and 0.214.
So , the correct answer is
c. We are 95 percent confident that the proportion of people in the sample who think climate change is a problem is between 0.146 and 0.214.
Answer:
It seems that problem might have an error.
population = 600 * e ^ (.02*t) where e = 2.718281828459
So, at day 1 we have
day 1 population = 600 * 2.718281828459 ^(.02*1) = 32.62
day 2 population = 600 * 2.718281828459 ^(.02*2) = 88.67
We can see that the population doubles in less than one day but the lowest of those multiple choices is 34.657 days
