Answer:
So probability will be 0.34
Step-by-step explanation:
We have given that a university admitted 100 students
In which 34 students are from two year community program
25 students are from private four year institution
And rest that is 100-34-25 = 41 students from public four year institutions
Number of ways for selecting two students from two year community program that is, from 34 students
And the number of ways in selecting the 2 students from total student
So probability will be
Answer:
- y =
+ 7
Step-by-step explanation:
The graph that will lie above the x-axis will be having only positive values throughout its domain,
So, We have to check which graph is having y > 0 for every x.
- y = -
+ 7
clearly y will be negative for many values of x , as coefficient of variable is negative.
- y =
Put x = 0, you will get y as negative .
- y =
Since, Square of anything will always be positive , and here constant term is also positive , so, It will always be positive .
Thus, it is having its graph always above x axis.
- y = x - 7
Put x = 0 , y = -7, which is negative
