If you roll a number cube 36 times how many times do you expect to roll a 1

1 answer:

4 0

Probability of a Die* rolling a 1 = 1/6
So you did it 36 times, ASSUMING it is a FAIR die, 1/6 * 36 = 6
You expect it to roll 6 1s

Answer.....15ft by 12ft

Explanation:

Area = Length × Width

180 = LW....make W the subject of formula

;W = 180/L

Perimeter = 2L + 2W

54 = 2L + 2(180/L)...sub W with the formula above...

then simplify the equation and obtain...

2L^2 - 27L + 180 = 0....then solve using the quadratic formula....then obtain..

;L = 15ft....after obtaining L = 15...then substitute into the W = 180/L equation...

where W = 180/15 = 12ft

there you have...Length = 15ft and Width = 12ft
