Answer:
4) 6 students
5) 7 fewer students
6) No, you can not tell from the frequency table how many students ran a mile in exactly 12 minutes.
Step-by-step explanation:
4) you’d look at the row from 8:00-8:59.
5) Add the first two rows together (6+2=8), then subtract that by the sum of the last two rows (9+6=15), which is 7
6) There’s no pattern in the frequency table, and the data points would be plotted differently since it’d be from a range of times, not one set time.
Hope this helped, sorry if I’m wrong on #6 ;)
Answer:
x-3/y
Step-by-step explanation:
thats the expression
-2 1/2 / 6 would be -5/12, just turn - 2 1/2 into a decimal and divide by 6 :)
Y=3x+2 when x=-3
=> y= 3(-3)+2 = -9+2 =-7
