Answer:
Step-by-step explanation:
in y = mx + b form, the slope is in the m position and the y int is in the b position
y = -2x + 3.....slope is -2 and y int is 3
y = -2x - 1...slope is -2 and y int is - 1
same slope, different y int's....means parallel lines...NO SOLUTION
learn this...it helps
same slope, different y int's = no solution
different slopes, different y int's = 1 solution
same slope, same y int's = infinite solutions
Answer:
Length of NO is 15
Step-by-step explanation:
because
NO = MO-MN
Answer:
The probability that all three have type B+ blood is 0.001728
Step-by-step explanation:
For each person, there are only two possible outcomes. Either they have type B+ blood, or they do not. The probability of a person having type B+ blood is independent of any other person. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
The probability that a person in the United States has type B+ blood is 12%.
This means that 
Three unrelated people in the United States are selected at random.
This means that 
Find the probability that all three have type B+ blood.
This is P(X = 3).


The probability that all three have type B+ blood is 0.001728
Answer:
C. 50
Step-by-step explanation:
Here we have to look at the given graph and find the answer.
The vertical axis represents the price and cost per unit. That is represented by P.
The horizontal axis represents the units of output, that is represented by q.
We need to find the number of units when p = $55.
By look at the graph of the curve MC, when P = $55, the number of units is 50.
Therefore, the answer is C. 50.
Hope this will helpful to understand the concept.
Thank you.
