PLEASE HELP
Find the value of x and y. Write your answer in simplest radical form.

Y=10

x=14.14

Step-by-step explanation:

Because the two smaller angles are equal, it is an isosceles triangle with both legs equal in length.

so y=10

By the Pythagorean theorem, x^2=10^2+10^2

x^2=200

x=14.14

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

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

have a good day!
