Answer:
Theoretical probability: 50/100 or 50%
Experimental probability: 12/20 or 60%
Step-by-step explanation:
Let's find out both probabilities asked.
Theoretical probability:
In the whole bank, here are 100 coins (20 nickels + 30 quarters + 50 one-dollars), among which there are 50 one-dollar coins. So the probability to pick up a one-dollar coin is 50 out 100, so...
TP = 50/100 or 50%
Experimental probability:
For the experimental probability, we know Jonathan picked out 20 coins, out of which 12 were one-dollar coins, so the probability is 12 out of 20...
EP = 12 / 20 = 60%
Answer: X = -36
Step-by-step explanation:
X/-2 = 18 we need to get the variable alone, so we need to get rid of the /-2 to get x alone. And whatever we do to one side we have to do to the other so:
X/-2 = 18
X/-2 • (-2) = 18 • (-2)
The /-2 cancels out so we are left with
X = -36

I hope this helps you
6 (x^2+3x)=0
x (x+3)=0
x=0
x+3=0
x= -3
6x+4=4x-2 subtract four x to get 2x+4=-2 and subtract 4 and get -6 and divide it by two to get -3
