On the average, only 1 person in 1000 has a particular rare blood type. a) Find the probability that, in a city of 10,000 people, no one has this blood type. b) How many people would have to be tested to give a probability greater than 1/2 of finding at least one person with this blood type?

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
