X+4=y=-2x-2
x+4=-2x-2
add 2x to both side
3x+4=-2
minus 4 both sides
3x=-6
divide 3
x=-2
sub back
y=x+4
y=-2+4
y=2
(x,y)
(-2,2)
Answer:
120 people [see below]
Step-by-step explanation:
48 out of 120 people like baseball.
That is about 48/120 = 0.4 [40%]
Now, 3/5th of THOSE, play baseball, so
0.4 * 3/5 = 0.4 * 0.6 = 0.24 [24%].
Thus, we have seen that around 24% of total people taken would play baseball.
Now, we take 500 people, so 24% of them would be expected to play baseball.
That is 0.24 * 500 = 120 people
