ANSWER:
The probability is 0.107 or 10.7%
STEP-BY-STEP EXPLANATION:
The probability is calculated with the number of people who are in that age range and meet the study conditions and the total number of people.
We can determine both data in the table, therefore
One day and 6 hours since one day is 24 hours 6 mores hours equals the 30 hours
Answer:
1. 0.1445
2. 0.3426
3. 0.6574
Step-by-step explanation:
Let L be the event that there is liquid in the bag
Let + the be event of a positive test.
we are given:
P(+ | L) = 0.99
P(+ | L') = 0.10
P(L) = 0.05
1. Find P(+), use the Law of Total Probability to do this:
P(+) = P(+|L)P(L) + P(+ | L')P(L')
= 0.99 * 0.05 + 0.1 * (1- 0.05)
= 0.1445
2. Find P( L | + ) = P( L ∩ + ) / P(+) . . . definition of conditional probability
= P( + | L ) P(L) / P(+) . . . again using definition of conditional probability
= 0.99 * 0.05 / 0.1445
= 0.3426
3. P( L' | + ) = 1 - P( L | + ) = 1 - 0.3426 = 0.6574
9x8-[18+(15+60/4)]+10
First, solve the inner parentheses:
(15+60/4) 60/4= 15
15+15= 30
Next, add the 18 and the 15, since they are still inside the parentheses:
18+15= 33
9×8-(33)+10 Is what we're left with.
Multiply: 9×8= 72
72-(33)+10
Subract: 72-33= 39
Add: 39+10= 49
The simplified answer is 49.
Pump A = 45 mins
Pump B = 35 mins
Pump A and B = (45 x 35) / ( 45 + 35) = 19.69 mins (nearest hundredth)
