Answer:
48
Step-by-step explanation:
It is b: False 1,729 isn’t divisible by 9
X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
Answer:
30 h
Step-by-step explanation:
Formula
speed = distance/time
We clear time from it
time = distance / speed
time = ?
distance = 15 km
speed = 0.5 km/h
time = 15/ 0,5 = 30 h
Ok, so find something you can divide with both 6 and 2. You should get 2. So when you divide 2 and 2, and 6 and 2, you get 1/3.
So the simplest form of 2/6 is 1/3.
