Three ballet dancers are positioned on stage. Wanda is straight behind Simon and directly left of Jaylen. If Simon and Wanda are 4 feet apart, and Jaylen and Simon are 5 feet apart, what is the distance between Wanda and Jaylen?

Step-by-step explanation:

Draw a picture. You have a right triangle with hypotenuse = 5 and one leg = 4.

length of remaining leg = √(5²-4²) = 3 ft

point farming, sorry, other answer is correct

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
