Step-by-step explanation:
4×3-(-3)=12+3=15
3(2×(-3)+3)=3(-6+3)=(3×(-3)=-9
Answer:
Y
opportunity cost
Step-by-step explanation:
The Production Possibilities Curve, shows the maximum combinations of two goods a theoretical economy can produce with the current state of technology and given the available resources.
Any increase in the production of one commodity must be done at the expense of the other, the opportunity cost of the good increased is the number of unit of the other that we have to give up.
in this question the opportunity cost of producing 10 more unit of good X is the 5 units of good Y that was given up.
Answer:

And using the cdf we got:

Step-by-step explanation:

The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

And 0 for other case. Let X the random variable that represent the random variable of interest and we know that the distribution is given by:

We know the variance on this case given by :

So then the deviation is given by:

And if we solve for
we got:

The cumulative distribution function for the exponential distribution is given by:

Solution to the problem
And for this case we want to find this probability:

And using the cdf we got:

Answer:
The answer is A.
