This is a true statement.
Consider two events A and B. We say they are complementary if P(A)+P(B) = 1
This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.
---------
Example:
A = the event it rains
B = the event it does not rain
P(A) = 0.30 = 30% chance of rain
P(B) = 0.70 = 70% chance it does not rain
P(A)+P(B) = 0.30+0.70 = 1
So this shows the two events are complementary.
Answer:
The answer is "Principal of marginal analysis".
Step-by-step explanation:
To determine unless the benefits of even an aggressive resource would outweigh its costs, and therefore increase utility, individuals and businesses can use a valuation model to compare the risks versus the benefits of more activities, like whether to create or consuming more. It's the amount during which net value is greater than or equal to marginal cost that's the optimal quantity in this situation. The amount where the marginal social cost curve and consumer surplus line connect.
Answer:

Step-by-step explanation:
Given



Required
List out the sample space
To do this, we simply pick 1 item in each category, without repetition.
So, we have:

At th x-intercept y=o
∴40x + 70 = 0
40x = -70
x = -70/40
x = -1.75
x intercepr = (-1.75,0)
<u>Answer:</u>
The correct answer option is B.
<u>Step-by-step explanation:</u>
We are given a graph with different intervals A, B, C and D and we are to figure out whether which of these intervals on the graph can be describes as linear increasing.
From the given interval options, we can see that C is constant while the intervals A and D are decreasing linear.
Its the interval B which can be describes as linear increasing since it has a positive slope.
