g Let X be a continuous random variable with pdf f(x) = ( k x4 x > 1 0 x ≤ 1 (a) (5 points) Determine the value of k for which f(x) is a legitimate pdf. (b) (5 points) Obtain the cumulative distribution function. (c) (5 points) Use the cdf from (b) to determine the probability that X is greater than 2. (d) (5 points) Obtain the expected value and variance of X.

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

43

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
