A 3-column table with 3 rows. Column 1 is labeled Element with entries Sodium (upper N a), Oxygen (upper O), and Iron (upper F e). Column 2 is labeled electron configuration with entries 1 s superscript 2, 2 s superscript 2, 2 p superscript 6, 3 s superscript 1; 1 s super 2; 2 s super 2, 2 p super 4; and 1 s super 2, 2 s super 2, 2 p super 6, e p super 6, 4 s super 2, 3 d super 6. Column 3 is labeled number of valence electrons with entries A, B, and C.

Line gh passes through points (2, 5) and (6, 9). which equation represents line gh? y = x + 3 y = x – 3 y = 3x + 3 y = 3x – 3

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?

Kendra had twice as much money as kareem. kendra later spent $8 and kareem earned $6. by then,the two had the same amount of money. how much money did each have originally?
