Answer:
Answers are in bold in explanation
Step-by-step explanation:
We are given the equation:
y = -7x + 8
The first x value is 0
y = -7(0) + 8
y = 8
(0, 8)
The next x value is 7
y = -7(7) + 8
y = -41
(7, -41)
Now we are given the Y value instead of X, so we do this:
36 = -7x + 8
Subtract 8 on both sides to leave -7x alone
28 = -7x
Divide by -7 on both sides to isolate x
-4 = x
(-4, 36)
39 students. 25% of 52 is 13. that is absent students. 52-13=39 which is present students
Answer: 73.55%
Step-by-step explanation:
p = (100-a) e^-b(0.07)
we have a = 20 and b =1.2
= (100-20) e^-(1.2)(0.07)
= 80(e^-0.084)
= 80(0.919431)
= 73.55%
If you mean 
, then the answer is going to be
6.73 - 2 = 4.73
4.73/2 = 2.365 (though it may be 2.37 because you have to round it)
