Answer:
Step-by-step explanation:
a) P(X > 6) = (9.5-6)/(9.5-5.5) = 3.5/4 = 0.875
b) P(X < 7) = (7-5.5)/(9.5-5.5) = 1.5/4 = 0.375
c) E(X) = (9.5+5.5)/2 = 7.5
Standard deviation = (9.5-5.5)/sqrt(12) =4/3.46 = 1.154
P= 1.156*2/(9.5-5.5) = 2.308/4 = 0.577
d) P(X > t) = 0.25
(9.5-t) /(9.5-5.5) = 0.3
9.5-t = 1.2
t = 9.5-1.2 = 8.3
There are 4 choices of meats from which you take 3, so there are
4! / (3! (4 - 3)!) = 4! / (3! 1!) = 4!/3! = 4
possible choices of 3-meat combos.
Answer:
x = 7
Step-by-step explanation:
Answer:
20y - 20
Step-by-step explanation:
We multiply the first term and the second term in the parentheses by the 4. That means we do:
4(5y) + 4(-5)
And we simplify to get:
20y - 20
Tank Volume = length X Broad X height
So here Length is 8 m , broad is 3 m and let height is H m
So the volume of the tank will be = ( 8 X 3 X H ) m3
So ( 8 X 3 X H ) m3 = ( 8 X 3 X H ) X 1m3 , here 1 m3 = 1000 L
So the amount of water this tank can take is =
= (8 X 3 X H ) X 1m3
= (8 X 3 X H ) X 1000L
= 24000 X H L
And it is given that the tank is 14400L water ,
So we can calculate
24000 X H = 14400
So , H= 14400/24000
So , H = 0.6
So , Height of the tank is 0.6 m
