Male cats are either black (B) or orange (O). Females are black, orange, or calico, which has patches of black and orange. Calico is formed from the codominance between the two alleles in the heterozygote, so a calico cat is (XB XO). Give the genotype and phenotype ratio of a cross between an orange male cat and a calico cat.
The trait that is masked by the dominant trait is the _____ trait.
recessive
cross
purebred
hybrid
At a tennis tournament, a statistician keeps track of every serve. The statistician reported that the mean serve speed of a particular player was 87 miles per hour (mph) and the standard deviation of the serve speeds was 13 mph. Assume that the statistician also gave us the information that the distribution of the serve speeds was bell shaped. Use the 68-95-99.7 rule to answer the following questions.
a) What is the approximate percentage of serves between 48 and 126? Do not enter the percent symbol.
Determine the mass in grams of NH3 formed from 1.34 moles of nitrogen
The laws of optics also apply to electromagnetic waves invisible to the eye. A satellite TV
dish is used to detect radio waves coming from orbiting satellites. Why is a curved reflecting
surface (a “dish”) used? The dish is always concave, never convex; why? The actual radio receiver
is placed on an arm and suspended in front of the dish. How far in front of the dish should it be
placed?

Suppose Natasha currently makes $57,000 per year working as a manager at a cable TV company. She then develops two possible entrepreneurial business opportunities. In one, she will quit her job to start an organic soap company. In the other, she will try to develop an Internet-based competitor to the local cable company. For the soap-making opportunity, she anticipates annual revenue of $483,000 and costs for the necessary land, labor, and capital of $434,000 per year. For the Internet opportunity, she anticipates costs for land, labor, and capital of $3,204,000 per year as compared to revenues of $3,273,000 per year.
