Average = (Sums of the observations)/(Number of observations) Worked-out problems based on average: 1. The mean weight of a group of seven boys is 56 kg. The individual weights (in kg) of six of them are 52, 57, 55, 60, 59 and 55.Distance, rate and time problems are a standard application of linear equations. When solving these problems, use the relationship rate (speed or velocity) times time equals distance. r⋅t = d r ⋅ t = d. For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h) (4h) = 120 km.Q What was that homework grading policy again?. A Most (about 2/3) of your grade will be based on your performance on the problem sets, each of which counts equally. On each problem set that you hand in late without a good excuse, you will be penalized by having your score for that problem set multiplied by the factor (2/3) N, where N is the number of late days (rounded upwards to an integer).Math 55 is a two-semester long freshman undergraduate mathematics course at Harvard University founded by Lynn Loomis and Shlomo Sternberg.

Because adding two odd numbers produces an even number, but adding even and odd (in any order) produces an odd number. Lucas Numbers. Starting the sequence with 2 and 1 we get the "Lucas Numbers". They get closer and closer to the powers of the Golden Ratio:Step 1: To get the sum of weighted terms, multiply each average by the number of students that had that average and then sum them up. 80 × 10 + 60 × 15 = 800 + 900 = 1700. Step 2: Total number of terms = Total number of students = 25. Step 3: Using the formula, Answer: The average score of the whole class is 68. Be careful! ….

So let's figure out what that is. The volume of the tank is going to be 9 foot by 5 foot times 12 feet. That's the volume of the tank. Tank volume. And from that, we want to subtract the metal box volume. So minus 4 foot by 8 feet by 7 feet. This is 4 feet wide. It is 8 feet-- they say it's 7 feet high.Decide whether the system has a solution (and if it does, nd all solutions) by solving the system for each prime factor separately. 1. n2 11 (mod 35) Working over each prime factor separately gives n2 1 (mod 5) and n2 4 (mod 7), so n = 1 (mod 5) and n = 2 (mod 7).an inner product on L(V).
