3. Last year, the numbers of calculators produced per day at a certain factory were normally distributed with a mean of 560 calculators and a standard deviation of 12 calculators. (a) On what percent of the days last year did the factory produce 572 calculators or fewer?

(b) On what percent of the days last year did the factory produce 584 calculators or more?

(c) On what percent of the days last year did the factory produce 548 calculators or fewer?
Please HELP

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
