The answer is y=-1/2x+4 that is if you are finding y. But if you are finding x it is x=-2y+8.

Answer:
We have, y=f(x)
From graph, when x = 2, y =f(x)=-5. So, functional value at x=2, f(2) = -5
Answer:X=4
Step-by-step explanation:
Congruent triangles method
AB/DB=BC/EC
10-x+x/10-x=3+2/3
10/10-x=5/3
30=50-5x
30-50=-5x
-20=-5x
X=4
We are looking to find P(X>60 students)
X is normally distributed with mean 50 and standard deviation 5
We need to find the z-score of 60 students

To find the probability of P(Z>2), we can do 1 - P(Z<2)
So we read the probability when Z<2 which is 0.9772, then subtract from one we get 0.0228
The number of students that has score more than 60 is 0.0228 x 1000 = 228 students
