Answer:
a) 0.8333
b) 0.75
c) 0.8181 or 0.9090
Step-by-step explanation:
a)
The probability the visitor selects an authentic painting is
10/12 = 0.8333
b)
Since the opinion of the expert does not depend on your choice, the events are <em>independent</em>, so the probability that the expert says is authentic and it really is, is
0.8333*0.9 = 0.75
c)
If the expert decides the painting is a copy and it is not, then there are 11 paintings of which 9 are authentic, so the probability the visitor selects a new original painting is
9/11= 0.8181
If the expert decides the painting is a copy and it is, then there are 11 paintings of which 10 are authentic, so the probability the visitor selects a new original painting is
10/11= 0.9090

Determine the line equation
This question will be answered using linear interpolation.
This is represented as thus:
Substitute values for x1,x2,y1 and y2
Cross Multiply
Make y the subject
Isn’t it the theoretical probability?
Answer:
-11
Step-by-step explanation:
plug -3 in x values.
h(-3) = -3^2 -2
=-11
All you have to do is find the area of all the shapes and add them so length times height besides the triangle which is 1/2(l*h)
