Answer:
76.92 percent win rate 23.08 lose rate
Step-by-step explanation:
That means you got 6 right, and since it is out of 10, 60 percent. However, since it was only out of ten your teacher may choose to weigh it differently. But, 6/10 is 60 percent.
Answer:
a) The probability of not having failures in 8 days is 0.7866
b) The probability of having at least 1 failure in a 24-hour day is 0.5132
Step-by-step explanation:
a) Lets call X the number of failures in a 8 hour period. Since it is 8 hours insstead of 1, the mean will be 8*0.030 = 0.24. As a consequence, the probability that there are no failures in this period (in other words, X = 0), is
b) Lets call Y the number of failures in 24 hours. Y has mean 24*0.03 = 0.72. The probability that Y is at least 1 can be computed by calculating the probability that Y is equal to 0 and substract from 1 this number (because obtaining 0 failures is the complementary event). The probability of Y being equal to 0 is
Thus, the probability of having at least 1 failure in a 24-hour day is 1-0.4868 = 0.5132
Answer:

Step-by-step explanation:
The pints of paint that Mike needs to buy in order to paint 4 boxes is 9 pints.
How many pints is needed?
The first step is determine the total surface area of a box.
Total surface area of a cuboid = 2 (lw + wh + lh)
where:
l = length
w = width
h = height
2 x[ (5 x 9/2) + (9/2 x 7/2) + (5 x 7/2) ]
2 x ( 45/2 + 63/4 + 35/2) = 111.5ft
The second step is to determine the total surface area of 4 boxes:
111.5 x 4 = 446
Now, divide 446 by 50
446 / 50 = 9 pints
