The rainfall duration at Toronto Pearson International Airport follows an exponential distribution with a mean of 2.725 hours. Suppose it has been raining at the airport for 2 hours already. True or false: the probability that the total duration of rainfall at the airport is less than 4.2 hours is equal to the probability that the total duration of rainfall at the airport is less than 2.2 hours (i. e., equal to the probability you calculated in previous question).

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

yes   because as the functions are graphed they eventually will intersect unless otherwise

step-by-step explanation:

the radius is 2 times the diameter.
