Answer:
*see graph below*
Step-by-step explanation:
y = mx + b
m = slope (rise over run)
b = y-intercept
Corresponding with the given equation, the graph below has a y-intercept of 5, and a slope of
or 2.
Answer:
b. because m = -5
Step-by-step explanation:
y = -5x +9
m (gradient) is the coefficient before the 'x' term

I think it's question number three. Sorry if the link dosen't work.
Answer:
a) P=0.0225
b) P=0.057375
Step-by-step explanation:
From exercise we have that 15% of items produced are defective, we conclude that probabiity:
P=15/100
P=0.15
a) We calculate the probabiity that two items are defective:
P= 0.15 · 0.15
P=0.0225
b) We calculate the probabiity that two of three items are defective:
P={3}_C_{2} · 0.85 · 0.15 · 0.15
P=\frac{3!}{2!(3-2)!} · 0.019125
P=3 · 0.019125
P=0.057375
