He number of bacteria in a refrigerated food product is given by N(T)=23T^2−56T+1, 3

where T is the temperature of the food. When the food is removed from the refrigerator, the temperature is given by T(t)=5t+2.5, where t is the time in hours.

a. Find the composite function N(T(t)).

b. Find the time when the bacteria count reaches 6,752.

Round your answer to two decimal places.

a) 14/17

b) 3/14

Step-by-step explanation:

6+13+9+4+2 = 34

a) P( C or better ) = (6+13+9)/34

= 28/35 = 14/17

b) P( A/C or better ) = 6/28 = 3/14
