Using only a pencil and paper, write a cubic polynomial function that could represent the curve shown (here, x represents the distance, in feet, along the horizontal axis from the western base of the hill, and H(x) is the height, in feet, of the land at that distance from the western base). Be sure that your formula satisfies H(400) = 1500.

Lems1. the following data set represents the scores on intelligence quotient(iq) examinations of 40 sixth-grade students at a particular school: 114, 122, 103, 118, 99, 105, 134, 125, 117, 106, 109, 104, 111, 127,133, 111, 117, 103, 120, 98, 100, 130, 141, 119, 128, 106, 109, 115,113, 121, 100, 130, 125, 117, 119, 113, 104, 108, 110, 102(a) present this data set in a frequency histogram.(b) which class interval contains the greatest number of data values? (c) is there a roughly equal number of data in each class interval? (d) does the histogram appear to be approximately symmetric? if so,about which interval is it approximately symmetric?

Ill mark the brainliest if you me with the these three questions 7,8,9
