Mrs Jenson collected the results from 20 maths tests. She wrote the results like this. 21 , 27 , 31 , 6 , 44 , 26 , 18, 5 ,17 ,25, 43, 22, 19 ,11, 10 ,20, 31 ,41 ,0, 7 simplify the results and group them in the frequency table. What is the tally and the frequency?

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
