Let the joint pdf of x and y be f (x, y) = 12e−4x−3 y , x > 0, y > 0. a. find the marginal pdf ’s of x and y. b. are x and y independent? c. find the conditional pdf f1(x|y). d. find the marginal cdf ’s of x and y. e. find p(1 < y < 3). f. find p(1 < y < 3|x = 3). g. find p(x > 2, 1 < y < 3).

if this is really you s much. i only have 3 points left and i have 2 questions to ask

can someone answer this question plz

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to

have a nice day!
