What is the sum
of the series it
a = 4,0 = 73, and n = 24?

Step-by-step explanation:

Do you mean last term ( I ) =73

If so use the formula..

Sn= n/2 ( a+l )

= 24/2 (4 +73)

= 12×77

= 924

the distance between point a and point b is 6 units

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
