Answer:
D) 0.51, and do the homework
Step-by-step explanation:
First, we have the event "Probability of give a pop quiz" and event 2 "Probability of not doing homework".
The soccer game, and the pop quiz are not related, which means that the outcome of one or another event, will not affect the fact of the soccer game to be realized, so these 2 previous events are independent events, you can either have the quiz and not doing the homework, or even not have the quiz but still do the homework, the result of one will not affect the outcome of the other, hence:
P(A∩B) = P(A) * P(B)
Replacing the data we have:
P(A∩B) = 0.6 * 0.85
P(A∩B) = 0.51 or 51%
This result is lower than 80%, therefore, you'll do the homework
Answer:
7564.9
Step-by-step explanation:
The sum of 5/30 + 4/6 would equal 25/30 because you would want to find a common denominator, which would be 30, but then you would want to simplify 25/30 because both the numerator and the denominator are both divisible by 5. so the final answer would be 5/6. Hope this helped! -Julia
146? because it's 20+120+6...
The annual salaries at a particular company are approximately normally distributed with a mean is 0.42124
Manufacturing job :
Mean (m) = 40,000
Standard deviation (s) = 9000
Sales job :
Mean (m) = 35000
Standard deviation (s) = 9000
Probability of earning more than 45000 if one or the other job is selected;
Obtaining the standardized scores and probability for each :
Z = (x - m) / s
P(x > 45000)
Z = (45000 - 40000) / 9000 = 0.5555
= 0.56
P(Z > 0.56) = 0.28774(Z probability calculator)
For sales
P(x > 45000)
Z = (45000 - 35000) / 9000 = 1.1111111
= 1.11
P(Z > 1.11) = 0.1335 (Z probability calculator)
0.28774 + 0.1335 = 0.42124
