g statements is correct regarding the number of students and the number of gold medals won? A histogram titled Gold Medals Won is shown. The horizontal axis is labeled Number of Gold Medals with bins 0 to 2, 3 to 5, 6 to 8, and 9 to 11. The vertical axis is labeled Students with values from 0 to 10 at intervals of 1. The first bin goes to 4, the second goes to 6, the third goes to 8, and the last goes to 2.
A total of 8 gold medals were won by all the students.
Eight gold medals were won by 6, 7, or 8 students.
A total of 8 students won all the gold medals.
Eight students won 6, 7, or 8 gold medals.
We see that the third bin is labelled 6 - 8. Since this is on the horizontal, or x, axis, this means that the students in this "bin" have won 6 - 8 medals, which is the same as saying winning 6, 7, or 8 medals.
Because this "bin" goes to 8, that means that there are 8 students who earned this many medals.
Frequency corresponding to 6 - 8 is 8 which means 8 students won 6 to 8 gold medals, i.e 6 7 or 8 gold medals (because no. of medals has to be a natural number)
D. y=mx+b. m being slope and b being the y intercept. so the equation for the line is y=3x+2 and to be parallel your m must be the same number so D. 3x
