Answer:
60pi = ⅓ × pi × r² × h
180 = r²h
Assuming r and h are whole numbers,
r = 3 m , h = 180/3² = 20 m
Diameter = 6 m
Or,
r = 6 m, h = 180/6² = 5 m
Diameter = 12 m
Answer: x = 11
Step-by-step explanation:
x+3 = 42/3 = 14
x = 11
Answer:
The answer should be that Q is (-3,-2)
Step-by-step explanation:
Look at it this way:
When you flip a coin, the probability of it landing with EITHER side showing
is 100%.
This leads us to the rule ...
The sum of the probabilities of
all possible outcomes is 100%.
For a coin: (probability of heads) plus (probability of tails) = 100%.
That just says: We're 100% sure that the coin will land with either
heads or tails up.
An "honest" coin gets heads 50% of the time and tails the other 50%.
But if the coin is all bent and squashed and has a feather stuck to
one side and a wad of gum on the other side so that it comes up
heads 70% of the time, then the coin isn't 'honest'. But it still has to
land EITHER heads OR tails, so the sum of the probabilities is still 100%.
So the probability of heads is 30%.
