Answer:
b. The margin of error would decrease.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
In which z is related to the confidence level, 
is the standard deviation of the population and n is the size of the sample.
This means that the margin of error is inversely proportional to the size of the sample, which means that if the sample size increases, the margin of error decreases.
In this question, the sample size is increased, leading to a smaller margin of error. So the correct answer is given by option b.
The pudu weighed approximately 1 pound at birth.
Given that the New York Queens Zoo celebrated the birth of a Southern pudu deer in July of 2013 which tipped the scale of a mere 0.45 kg, to determine, given that one kilogram is approximately equal to 2.2 pounds, about how many pounds did the pudu weigh at birth, the following calculation must be performed:
- 1 = 2.2
- 0.45 = X
- 0.45 x 2.2 = X
- 0.99 = X
Therefore, the pudu weighed approximately 1 pound at birth.

The greatest place value is the tens spot which 2 is in the tens spot so we need to round up since 5 is next to the 2. The answer would be 30
Answer:
<em>Answer: C</em>
Step-by-step explanation:
<u>The Cosine Function</u>
The graph of a cosine function is a sinusoid that starts at its maximum value of 1 at x=0 and takes x=2π radians to complete a full cycle. The function of the parent cosine function is:
Both the amplitude A and the angular frequency w of a cosine can be modeled by the function
The graph of the cosine function shown in the figure has an amplitude of A=3 and it completes a full cycle at x=π/2, thus:
Thus:
Therefore, the equation of the sinusoid is:
Answer: C
