The mean is 1.79, the median is 1.8, and the mode is 1.5. To find the mean, add the numbers together and divide that sum by 6, which is how many numbers are in the set. (1.0 + 1.5 + 2.25 + 1.5 + 2.4 …

To find the median of a trapezoid we need the top and bottom lengths. Start by constructing line BH such that BH is perpendicular to AD and H is on the line AD. We can AD using BC and a little trig. …

Nov 6, 2015 · The mean (average) and standard deviations can be obtained directly from a calculator in stat mode. This yields barx=1/nsum_(i=1)^nx_i=219,77 Strictly speaking, since all the data points in …

Oct 29, 2016 · To find the median (middle) of the scores, we must put them in order from least to greatest first. 78,82,90,96,100,100 Since there are an even number of scores, the median will be the …

Find the median from following data? There are 12 data-points between 10 and 19; 19 data-points between 20 and 29; 31 data-points between 30 and 39; 27 data-points between 40 and 49; 16 data …

If A (-3,1), B (8,-2) and C (4,16) are vertices of a triangle and AM is a median of this triangle, how do you show that the coordinates of M is (6,7)?

The sum of two numbers is 37. Their product is 312. What are the numbers? How do you find the mean, median, and mode of the following frequency distribution table? How do you find the exact value in …

How do you find the z-score for an IQ test score of 142 when the mean is 100 and the standard deviation is 15? How do you find z-score given the data:-6, -9, -6, -4, 10? 1. 0.2321 2. -1.737 3. …

Is covariance a measure of variability? If the median is 1900, the mean is 2144.58, and the sample standard deviation is 884.07, then what is the sample variance? What is the variance of z=2x+3y, in …

What is the difference between a trapezoid and a rhombus? How do you prove this theorem on trapezoids and its median? The median (or mid-segment) of a trapezoid is parallel to each base and …
