Normal Approximation of the Sampling Distribution of a Sum Suppose that the expected number of phone calls that are handled by a switchboard in each second is 5.35. Assume that the distribution of the number of phone calls per second follows the Poisson distribution.
a. The number of phone calls that the switchboard is expected to handle in 1 minute is:___.
b. The 0.80-percentile of the number of calls per minute is (approximately) equal to: .
c. The probability that the switchboard will need to handle no more than 300 call in a minute is:.

rick would give her the best deal as he will charge $8.88 per hour

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
