Reduce terms: (sin x + sin 3x)/(cos x - cos 3x) =cos(2x)/sin (2x)
(sin x + sin 3x)/(cos x - cos 3x) = cot (2x)
The last line proves the identity (sin x + sin 3x)/(cos x - cos 3x) = cot (2x)
(PV=nrt) Divide nr from both sides to get t by itself. t=PV/nr
Answer with Step-by-step explanation:
Since we have given the conditions.
As we know that
Discrete random variables are those variables that can be measured in number.
Continuous random variables are those variables that can be measured in range.
a. The square footage of a pool - it will be a continuous random variables as square footage can take any value within an interval.
b. The last book a person in City Upper A read - It is not a random variable.
c. The time it takes to drive from City Upper A to City Upper B - it will be a continuous random variables as it take any value within an interval.
d. The time it takes for a light bulb to burn out
- it will be a continuous random variables as it take any value within an interval.
e. The amount of rain in City Upper A during July - it will be a continuous random as it can take any value within a range.
f. The time required to upload a file to the Internet - it will be a continuous random variable as it can take any value within any range.
