Answer: 0.12
Step-by-step explanation:
The expected number of accidents is a weighted average of the potential number of accidents and their probabilities:
= (0 * 0.935) + (1 * 0.03) + (2 * 0.02) + (3 * 0.01) + (4 * 0.005)
= 0.12
A. Your Choice

D. The walls are 8 * 20 ft and 8 * 25 ft, and there are 2 of each of those.
That means you are painting 720 ft^2
There is 1 gallon per 400 ft^2, so you need 2 gallons of paint.
It costs $13.98 per gallon, so you need $13.98 * 2 = $27.96
The Answer is 3 and if they are asking for the male ratio to female it would be 12:3
rounding decimals is very similar to rounding other numbers. If the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change.
For example, rounding 0.843 to the nearest tenth would give 0.8.
If the hundredths and thousandths places are fifty or more, the tenths place is increased by one. The decimal 0.866 rounded to the nearest tenth is 0.9
