When solving systems of we have at least two unknowns. A common example of a system of equations is a mixture problem. If I know that the solution I use to clean my car windows is 65% water and 35% cleaner, I have one relationship. If I also know that I only have a 3-liter spray bottle that gives me a second relationship. What do the unknowns in this system represent and what are the two equations that that need to be solved? Finally, solve the system of equations.

The lab experiment is repeated again with the same two glass plates and the same sodium lamp but with a different human hair. The space between the plates is filled with a transparent silicon grease that has n = 1.52. The glass plates each have refractive index 1.20. The separation between adjacent dark fringes is measured to be 0.750 mm. Calculate the diameter of the hair. (The wavelength emitted by the lamp is 589.3 nm. The length of the plates is 12.0 cm.)

A credit score is used by credit agencies (such as mortgage companies and banks) to assess the creditworthiness of individuals. Values range from 300 to 850, with a credit score over 700 considered to be a quality credit risk. According to a survey, the mean credit score is 703.1. A credit analyst wondered whether high-income individuals (incomes in excess of $100,000 per year) had higher credit scores. He obtained a random sample of 35 high-income individuals and found the sample mean credit score to be 716.6 with a standard deviation of 80.1. Conduct the appropriate test to determine if high-income individuals have higher credit scores at the alphaequals0.05 level of significance.

Mark wants to know how many families in his neighborhood plan to attend the neighborhood party. He puts all 80 of the neighborhood addresses in a hat and draws a random sample of 20 addresses. He then asks those families if they plan to attend the party. He finds that 20% of the families plan to attend the party. He claims that 20% of the neighborhood families would be expected to attend the party. Is this a valid inference?A. No, this is not a valid inference because he asked only 20 familiesB. No, this is not a valid inference because he did not take a random sample of the neighborhoodC. Yes, this is a valid inference because he took a random sample of the neighborhoodD. Yes, this is a valid inference because the 20 families speak for the whole neighborhood
