Answer:
C. (5, 3)
Step-by-step explanation:
this point is within the answer area... look below at the graph of both linear inequalities
For this case we have the following system of inequations:
We must replace each of the points and verify that the inequalities are met:
Point A: (1,1)
It is not fulfilled!
Point B: (-2,2)
It is not fulfilled!
Point C: (5,3)
Is fulfilled!
Is fulfilled!
Point D: (-4,4)
It is not fulfilled!
Thus, the point that is the solution of inequalities is:
(5,3)
ANswer:

Answer:
The correct answer to the following question will be "0.438".
Step-by-step explanation:
Just because Mrs. Gomes finds around 40% of students in herself high school are studying chemistry.
Although each student becomes independent of one another, we may conclude:
"x" number of the students taking chemistry seems to be binomial to p = constant probability = 0.40
Given:
Number of surveys
= 12
Exactly 4 students have taken chemistry:
On substituting the above equation, we get the probability of approximately "0.438".
So that the above would be the appropriate answer.
