Graph-like a histogram, a bar is drawn above each X value, so that the height Produce a continuous figure, which emphasizes the continuity of the variable. Is from interval or ratio scale, the bars are draw on so that adjacent bars y-axis (ordinate)-lists the frequenciesīar is drawn above each X value, so that the height of the bar corresponds to x-axis (abscissa)-lists the measurement scale categories Or percentile rank-the percentage of individuals in the distribution with Of each interval should be an easy number (5 or 10) and all intervals should be Should have about 5-10 intervals depending on range of data. The wider the interval, the more information that is lost. Intervals in the frequency distribution table.

How long would it take them to clean the garage if they worked together? Prepared by: Checked by: Reviewed by: KARL DOMINICK A. If the speed of the wind is 29mph, what is the speed of the plane in still air? HE: Albert clean the garage three hours, but it takes Jeneva four hours to do the same work. If the boat travels 94 miles downstream in the same time that it takes to travel 47 miles upstream, what is the speed of the boat in still water? ICT: The plane flies 450 miles with the wind 300 miles against the wind in the same length of time. Find the speed of the boat in still water. If Christian’s rate of travel is 4mph more than Joannes, at what speed does Christian travel? HUMSS: A boat goes 450 miles downstream in the same time it can go 360 miles upstream. Christian travels 104 miles in the same time that Joannes travels 96 miles. STEM: Christian and Joannes agree to meet in SM Manila for the weekend. In the time it takes the train to travel 160 miles, the truck travels 240 miles. ABM: A loaded moving truck 20mph faster than a PNR train. Given f ( x ) =− 3 x + 7, h ( x ) = 5 x 2 − 3 and g ( x ) = x 2 + 8 be a function. Find the inverse of the following equation 1.
