Answer:
you have a 2/10 chance which is 1/5 chance.
Step-by-step explanation:
add all the cards which is 10, after, put 2/10 and then simplify. which is 1/5
Answer:
a) X ~
b) μ = 100/3
c)
d) A battery is expected to last 100/3 months (33 months and 10 days approximately).
e) For seven batteries, i would expect them to last 700/3 months (approximately 19 years, 5 months and 10 days).
Step-by-step explanation:
a) The life of a battery is usually modeled with an exponential distribution X ~
b) The mean of X is μ = 1/0.03 = 100/3
c) The standard deviation is
d) The expected value of the bateery life is equal to its mean, hence it is 100/3 months.
e) The expected value of 7 (independent) batteries is the sum of the expected values of each one, hence it is 7*100/3 = 700/3 months.
prices are per 1000 so 100,000/1000 = 100
35 yo smoker pays 9.36 per 1000 so 9.36*100 = 936 per year
35 yo non smoker pays 7.85 per 1000 so 7.85*100 = 785 per year
936 -785 = 151
answer is A $151
Yes I believes so I hope I helped ya
Answer:
Where's the x?
I am assuming that the problem must be
-3 + 42 > 3x
if that is true, then
<u>x < 13</u>.
As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and
39 > 3 [39 is always greater than 3]
