An elevator was at the 4floor It traveled up 18 floors, down 7 floors, up 6 floors and down 2 floors. What floor did the elevator end up on? submarine was traveling at 62 feet below sea level. It rose 17 feet, dropped 250 feet, then rose 25 feet. What was the submarines Final position?

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
