Bronze is a mix, or alloy, of tin and copper. A metal worker needs 100 g of bronze that is 25% tín. He has one tin/copper alloy that is
5% tin and another tin/copper alloy that is 45% tin.
Let x = the number of grams of the 5% tin alloy.
Let y = the number of grams of the 45% tin alloy.
How many grams of each alloy should the metal worker combine?

Solve the equation below: (x+4)/6x=1/x a. x=2 b. x=0,2 c. x=-2 d. x=0,-2

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

Unaware that 35% of the 10000 voters in his constituency support him, a politician decides to estimate his political strength. a sample of 200 voters shows that 40% support him. a. what is the population? b. what is the parameter of interest? state its value c. what is the statistics of the interest? state its value d. compare your answers in (b) and (c) is it surprising they are different? if the politician were to sample another 200 voters, which of the two numbers would most likely change? explain
