Answer: 2/5

Step-by-step explanation:

Ben gives 35 to Sonia, 130 to Phill, 75 to Lance, in total he gives away 240 counters. the fraction of the counters left in his bag would be 400-240 which is 160 and so his fraction would be 160/400 and this in simplest form would be 8/20 if you divide by 20 and then to simplify that you can divide by 4 to get 2/5

H(x)= 8 1 ​ x 3 −x 2 h, left parenthesis, x, right parenthesis, equals, start fraction, 1, divided by, 8, end fraction, x, cubed
otez555 [7]

Answer:

m = 324

Step-by-step explanation:

The average rate of change is:

m = \frac{h(2)-h(-2)}{2 - (-2)}

h(-2) = 81\cdot (-2)^{3}-(-2)^{2}

h(-2) = -652

h(2) = 81\cdot (2)^{3}-(2)^{2}

h(2) = 644

m = \frac{644-(-652)}{2-(-2)}

m = 324
