At a school carnival, tickets can be purchased to participate in different activities. The table shows the total cost for different numbers of tickets.

8 | 2.00
12 | 3.00
20 | 5.00
30 | 7.50
50 | 12.50
What is the constant of proportionality that relates y, the total cost in dollars, to x, thenumber of tickets purchased?

Which represents the inverse of the function f(x) = 4x? h(x) = x + 4 h(x) = x – 4 h(x) = x h(x) = x

How to choose the sign of the radical in the denominator of the formula for the distance from a point to a line.

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
