.5 means half. 12 x 2 is 24. so, your equation would be x/2=12
Answer: 0.3741
Step-by-step explanation:
Poison probability ;
P(x) = [U(^x) e(^-U)] ÷ x!
Where U = mean
Note: e = exponential symbol
Number of checks that year = 171
Number of days in a year = 365
U = 171/365 = 0.468
Average checks per day = 0.4685
Probability that at least one check was written per day is can be calculated by;
P(not 0) = 1 - P(0)
Therefore,
P(x) = [U(^x) e(^-U)] ÷ x!
P(0) = [ 0.4685^0 * e^-0.4685] ÷ 0!
P(0) = [ 1 * 0.6259] ÷ 1
P(0) = 0.6259
Therefore,
P(not 0) = 1 - 0.6259 = 0.3741
Answer:
I think the answer is 2/5
Step-by-step explanation:
There are 10 ducks and there are 4 of them that are multiple of 3 (9, 18, 21, 27).
You end up with 4/10 but that is not an option.
If you reduce it you will end up with 2/5
Answer:
x^2-3x+36
Step-by-step explanation:
The total length is 456 cm.
132+94+108+w+w=456
334+2w=456
2w=122
w=61
