Answer:
125 times.
Step-by-step explanation:
Prob(Heads) = 1/2.
Prob(Spinner lands on 2) = 1/4 ( as there are 4 sections on the spinner).
So the best prediction for the number of times this occurs in a 1000 trials
= 1/2 * 1/4 * 1000
= 1/8 * 100
= 125 times.

Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2
