Answer:
Step-by-step explanation:
total profit=income -cost
or
P(x)=R(x)-C(x)=-0.5x²+800x-100-(300 x+250)
or P(x)=-0.5x²+800x-100-300x-250
or P(x)=-0.5 x²+500 x-350
so (2)
Answer:
a)Discrete random variable
Step-by-step explanation:
A discrete random variable is a variable which can only take a countable number of values, it means only take values in the natural numbers.
A continuous random variable is a random variable where the data can take infinitely many values; the random variable take values in the real numbers
Then the number of free throw attempts before the first shot is a discrete random variable because these can be counted with the natural numbers.
Answer:
y= 50 + 4x, 130 meters and 82 meters.
Step-by-step explanation:
Given, a balloon is released from a 50 meter tall building and rises at the rate of 4 meters per second. So, the equation will be y = 50 + 4x, where x is time in seconds.
So, after 20 seconds, the balloon will be at
y = 50 + 4x= 50 + 4 X 20 = 50+ 80= 130 meters. Here, x = 20 seconds.
For, x = 8 seconds,
y = 50 + 4x= 50+4 X 8 = 50+32= 82 meters. So the balloon will be at 130 meters and 82 meters respectively.
