The speed with which utility companies can resolve problems is very important. gtc, the georgetown telephone company, reports it can resolve customer problems the same day they are reported in 80% of the cases. suppose the 15 cases reported today are representative of all complaints. a-1. how many of problems would you expect to be resolved today? (round your answer to 2 decimal places.) a-2. what is the standard deviation? (round your answer to 4 decimal places.) what is the probability 6 of the problems can be resolved today? (round your answer to 4 decimal places.) what is the probability 6 or 7 of the problems can be resolved today? (round your answer to 4 decimal places.) what is the probability more than 10 of the problems can be resolved today? (round your answer to 4 decimal places.)

Aboat's value over time is given as the function f(x) and graphed below. use a(x) = 400(b)x + 0 as the parent function. which graph shows the boat's value increasing at a rate of 25% per year?

What is the unit rate of, 75% high fiber chimp food to 25% high protein chimp food.

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
