Answer:
(a) 0.2824
(b) 0.0002441
Step-by-step explanation:
Assuming that the population is large enough to behave as a binomial distribution (between whites and non-whites), the probability of 12 out of 12 juros being white is:
Where p(w) is the proportion of the population that is white:
(a) for p = 0.90
The probability is 0.2824.
(b) for p = 0.50
The probability is 0.0002441.
Answer: 16/18 reduced is 89 :D
Step-by-step explanation:
In plain and short, we'll simply divide 180 by (4+5+9), and give 4 pieces of those to the ratio of 4, 5 to the ratio of 5 and 9 to the ratio of 9, thus
Answer:
I think it is group b
Step-by-step explanation:
The area of the room is given by:
A = (6) * (12)
A = 72 feet ^ 2
For each 40 watt bulb we have:
(515) / 72 = 7.152777778 footcandle
The number of 40 watt bulbs is:
N = (50) / (7.152777778)
N = 7, 40 watt bulbs
Answer:
will be required about:
N = 7, 40 watt bulbs
