Group of students was asked about the number of emails they each sent that day the results are: 0,1,1,2,4,4,5,7,7,8,11,12,16,19

Which histogram correctly shows the data?

There is a D but it would not fit.

Please help me

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

In which form is the following function written? y = - 2(x – 3)(x + 5)

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
