1. use both methods to find the distance between the points on the number line.
method a: count the number of units between the points.
method b: take the absolute value of the difference of the two numbers.
when taking the absolute value, show that the greater number or the lesser number can be the subtrahend (the number subtracted).

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to

Find two numbers if their sum is 91 and the ratio is 6: 7?

In the diagram, ab is tangent to c, ab = 4 inches, and ad = 2 inches. find the radius of the circle.
