Students in an engineering class designed model airplanes. The average distance flown was 48 feet. The table shows the difference from average for five students. A 2-column table with 5 rows. Column 1 is labeled Name with entries Shanquelle, Ceili, Ella, Vincent, Conner. Column 2 is labeled Difference (feet) with entries negative 1.3, two-fifths, negative 0.2, 1.5, negative one-fourth. Which statements are true? –1.3 is less than Two-fifths. 1.5 is less than –0.2. Two-fifths is greater than –0.2. Negative one-fourth is less than –0.2. 1.5 is greater than Two-fifths.

What are the relative frequencies to the nearest hundredth of the columns of the two-way table?

Find the difference (8ab+a+2) - (3ab+6)

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?
