8 0

The answer is 104.4 because 38+65 is 103. then you add the decimal part of the equation which is 37. If you are rounding to the nearest tenth it would be 104.4

38.94 rounds up to 40 as it is more than half-way between 30 & 40.
65.43 rounds up to 70. even though 65 is half-way, .43 makes it closer to 70 than 60.

40 + 70 = 110

A bin has 5 white balls and k black balls in it, where k is an unknown positive integer. A ball is drawn at random from the bin.

Answer:

Step-by-step explanation: The expected loss is 50 cents, we know that it is more likely to lose than win. It is therefore difficult to get-50, so the overall difference between the two possibilities is 2, 50/200=1/4, and the probability to win is 1/4, and the probability to lose is 3/4. Since (1/4)*3=3/4, the number of black balls is 3 times the number of white balls, so k=15.
