1point) a group of 20 hunters wait for ducks to fly by. when a flock of ducks flies overhead, the hunters all fire at the same time, each selecting a target at random and independently of the others. if each hunter independently hits his target with probability 0.5, and if all misses do not hit other ducks, what is the expected number of ducks that will be hit? assume that the number of ducks in a flock is a poisson random variable with mean 5. e[n]=

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!
