Dominic from "Dominic's Pizza" always bakes p pizzas each day. Currently, it costs him $10 per day to use a brick oven and $2 per pizza for the ingredients. One day Dominic realized that if he switched to an electric oven, the use of the oven would cost him $20 per day, but the ingredients would be cheaper, only $0.80 per pizza. This way, his total expenses for each pizza (including shared oven costs and ingredient costs) would be reduced by $1. Write an equation in terms of p to model the situation.

Kapil needed to buy a long wooden beam. he went to two sawmills that each charge an initial fee plus an additional fee for each meter of wood. the following equation gives the price (in dollars) of a wooden beam from the first sawmill as a function of its length (in meters). p = 5+20xp=5+20x

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

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'
