Answer: The required probability is 0.6.
Step-by-step explanation:
Since we have given that
It is uniformly distributed between 40 minutes and 90 minutes,
Probability that her trip will take longer than 60 minutes would be
here, a = 40, b = 90, α = 60
Hence, the required probability is 0.6.
6+3w (don't mind this it has to be 20 characters long)
Answer: 17.46
Step-by-step explanation:
X^2 = 7^2 + 16^2 = 49 + 256
X^2 = 305
X = sqrt(305)
X = 17.46
It is (6,11) just find the numbers that are in both sets.
Answer:
c. 5
Step-by-step explanation:
Counting the check digit, there are 12 digits, so this is a GTIN-12 code. Alternate digits are multiplied by 3 and the result summed with the sum of the other digits. The check digit is the amount required to make this sum be a multiple of 10.
(4 +9 +0 +0 +7 +2)·3 +(8 +0 +0 +3 +8) = 66+19 = 85
The check digit is 5, the number that must be added to this to make the total 90, a multiple of 10.
