distribution‚ the mean is 50 with a standard deviation of 6. Use Chebyshev ’s theorem to tell the probability that a number lies in the following interval. Round your results to the nearest whole percent. 2) Between 35 and 65 Ans: we have z = (35-50)/6 = -2.5 and z = (65-50)/6 = 2.5 So 35 and 65 lies within 2.5 standard deviation of mean By Chebyshev’s theorem we have the probability as 1 -1/k2 ‚ where k is the standard deviation within which the numbers In this case k = 2.5 So the required

I feel is much needed‚ all while checking off another class off the graduation checklist. I would really like to gain more confidence in math and test taking over the course of this semester. I have a tendency to get a little dyslexic with numbers especially on tests‚ which tends to be my number one concern with math. This will be my first time back in a math classroom since studying algebra‚ geometry‚ and trigonometry in high school. I do feel a little nervous about getting back in the swing

Math SL Investigation Type 2 Stellar Numbers This is an investigation about stellar numbers‚ it involves geometric shapes which form special number patterns. The simplest of these is that of the square numbers (1‚ 4‚ 9‚ 16‚ 25 etc…) The diagram below shows the stellar triangular numbers until the 6th triangle. The next three numbers after T5 would be: 21‚ 28‚ and 36. A general statement for nth triangular numbers in terms of n is: The 6-stellar star‚ where there are 6 vertices‚ has

Math Portfolio HL- Type 1 INVESTIGATINGRATIOS OF AREAS AND VOLUMES The purpose of this portfolio is to investigate the ratios of areas and volumes when a function y= xn is graphed between two arbitrary parameters x=a and x=b such that a‹b. Task 1 The general formula to find area A is [pic] The general formula to find area B is [pic] Therefore‚ the ratio of Area A to Area B is- = [pic] ÷ [pic] = [pic] × [pic] = n : 1 n:1 is the general conjecture formed.

Calories: 190‚ Protein: 7grams‚ and fat: 2 grams. In order to find out how much protein my math and equation would be based on this: There are 4 grams of calories per each gram of protein so I am going to multiply like this 4*7= 28‚ which means for every gram of protein I am consuming 28 calories. This is amazing because I never knew this. Nature Valley Granola Thins: Calories: 80‚ Fat: 4 grams‚ and protein 1 gram. In order to find out the calories per protein I am going again to multiply; 4*
