Answer:
A: yes because the sample is fairly small and is collected in a convenient manner
Answer:
The domain of a rational function consists of all the real numbers x except those for which the denominator is 0 . To find these x values to be excluded from the domain of a rational function, equate the denominator to zero and solve for x .

Hello there!
Here is a simple step you need to follow and remember it. You'll be able to find the percentage of any fraction next time.
First, start by transferring the fraction to decimal. To do that, divide the top number by the bottom.
74 ÷ 50 = 1.48
Second, multiply the decimal you got by 100
1.48 * 100 = 148%
Thus,
74/50 as a percentage is 148%
Good luck!
Consider a triangle ΔABC, where sides AB, BC and angle ∡C are given.
Angle ∡C is the angle opposite of side AB.
It says that the given side opposite the given angle is less than the other given side. It means AB < BC.
It says that the ratio of the longer side to the shorter side, multiplied by the sine of the angle opposite the shorter side, is less than 1. It means
· sin(C) < 1
We know about Law of Sines of Triangle is given by :-
\\
We got sin(A) < 1, and BC > AB.
Therefore, angle ∡A could be either acute or obtuse angle.
So, There will be two solutions for the angle ∡A.
⇒ option D is the final answer.
Answer:
It is failed to reject the null hypotehesis. There is no enough evidence that the proportion of investors who are risk-averse is not 0.6.
Step-by-step explanation:
We have to perform an hypothesis test of a proportion.
The null and alternative hypothesis are:
We state a significance level of 0.1.
The sample proportion is
The standard deviation is
The test statistic z is calculated as
The P-value of z=0.247 is P=0.8. This value is bigger than the significance level, so the efect is not significant.
It is failed to reject the null hypotehesis. There is no enough evidence that the proportion of investors who are risk-averse is not 0.6.
