Answer:
Step-by-step explanation:
The function of a continuous random variable, whose integral over an interval provides the likelihood that the value of the variable is just inside the same interval while The cumulative distribution function (FX) provides the possibility that the random variable X is not up to or equal to a particular amount x. the formula for calculating it is: Summing the values for every one of the outcomes less than or equal to x will give the solution.
The step by step explanation to this question are in the athached images below
7 sqrt(16*2) - 6 sqrt( 36*2)
7*4sqrt(2) - 6*6sqrt(2)
28sqrt(2) - 36 sqrt(2)
-8sqrt(2)
Try and use socratic it will show the answer
Answer:
The number of (2 X 4 ) foot tiles needed for 48 square feet is 6.
Step-by-step explanation:
The dimensions of the small tiles = 2 ft x 4 ft
Area that needed to be covered by tiles = 48 sq feet
Now, Area of 1 tile = LENGTH X WIDTH
= 2 ft x 4 ft = 8 sq ft
Now, 
= 
or, Number of tiles required = 6
Hence, the number of (2 X 4 ) foot tiles needed for 48 square feet is 6.
