Answer:

Time for bacteria count reaching 8019: t = 2.543 hours
Step-by-step explanation:
To find the composite function N(T(t)), we just need to use the value of T(t) for each T in the function N(T). So we have that:




Now, to find the time when the bacteria count reaches 8019, we just need to use N(T(t)) = 8019 and then find the value of t:


Solving this quadratic equation, we have that t = 2.543 hours, so that is the time needed to the bacteria count reaching 8019.

Answer:
1178.25cm^3
Step-by-step explanation:
Volume of a cylinder is given as V = Pi x r^2 xh
PI= 3.142
R = 5cm
H=15cm
So volume = 3.142 x 5cm x 5cm x 15cm
= 1178.25cm^3
Answer:
The most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles is 102.
Step-by-step explanation:
Consider the provided information.
Emanuel surveyed a random sample of 50 subscribers to Auto Wheel magazine about the number of cars that they own. Of the subscribers surveyed, 15 own fewer than 2 vehicles.
The probability of fewer than 2 vehicles is: 
Now it is given that there are 340 subscribers to Auto Wheel magazine.
Simply multiply the probability of fewer than 2 vehicles with 340.

Hence, the most reasonable estimate for the number of Auto Wheel magazine subscribers who own fewer than 2 vehicles is 102.
