Answer:
B
Step-by-step explanation:
in a 30,60,90 triangle the longer leg is rt3 times the value of the shorter leg and the hypotenuse is 2 times greater than the shorter leg.
A hypothesis is only tentative: to make sure it's valid, you have to test it.
The answer is B.
Explanation: A doesn’t make sense because he only has 3 tries not 4. C doesn’t make sense because he tried 3 times not 2 times
<span>Because a mean is an average, the means of each of the samples of 40 college presidents' incomes will have less of a skew than the actual income distribution in dollars of all of them. That is because outliers, like a president who is paid $2 million a year, will be averaged in with many others who are paid less. The shape of the curve of the means will depend upon how many different samples of 40 presidents are included, with the shape becoming more bell-like (normal distribution) the more random samples are included. Another consideration is how often the outliers are included and how big the income skew is that you start with. For example, if 2 college presidents are earning $2 million a year and the other 4,198 are earning $200,000 or less then the shape of your curve will depend greatly upon the number of times those two high earners are randomly selected and factored into the mean.</span>
