The score is given by:
z=(x-mean)/s.d
In the question above:
x=1300
mean=1200
s.d=200
Thus:
z=(1300-1200)/200
=100/200
=0.5
The answer is 0.5
(x + -5)(x + -4) = 0
is the anwser

Answer:
not linear
Step-by-step explanation:
this equation becomes y = -4x² + 32x which is a quadratic equation that, when graphed, forms an upside down u-shaped curve (upside down because the x² term is negative; if it's positive then the curve is u-shaped)
25/x=100/20 criss cross and u will get 500/100=5 then 5 students resivs A.
