Answer:
Step-by-step explanation:
f(-x) is a reflection of f(x) in the y-axis
Assuming that their exam success is independent then
P(both fail) = 1/4 x 2/5 = 2/20 or 1/10
28.2% of 1128
(28.2%)(1128)
(28.2/100)(1128)
(0.282)(1128)
318.096
The answer is 318.096
Well let's see.
If the figure is split up into 10 pieces, then
each piece is 1/10 of the whole figure.
If 2 of the pieces are shaded, then
2/10 of the whole figure is shaded.
How many pieces are left ?
There were 10 pieces all together, and
2 of them are shaded. Hmmm. I think
there are probably (10 - 2) = 8 of them left
that are not shaded.
8 pieces makes 8/10 of the whole figure.
Really that’s your question :> the answer is 5
