Jamie is conducting inventory at a public library, so they have to verify that each item from the catalog is in its correct loca
tion. At any given time, 97%, percent of the items are checked into the library (not checked out). Let B be the number of items that Jamie verifies to reach the first item that is checked out. Assume that each item's checked out status is independent. Find the mean and standard deviation of B.
The equation of the line has the form: y = ax+b parallel to the line y = -2x + 7 => a= -2 Passes through (4,1) => x=4, y=1 Substituting into the equation: 1= -2x(4) + b => b= 9 => y= -2x + 9
