At the start, you have 10 marbles in total and 6 red marbles. The probability of the first event is 6/10.
Since you do not place the marble back in, you now have 9 marbles in total and 3 blue marbles. This probability of the second event is 3/9.
To find the probability of both events occurring, we multiply the two probabilities together. (6•3)/(10•9)=18/90=1/5
Thus, there is a 20% chance of drawing a red marble then a blue marble without placing the red marble back in the bag.
Answer: Option 3
Step-by-step explanation:
p=total price.
Lets say total price is $100
p=$100.
20% of p=0.2p
p-0.2p=price after 20% off
p-0.2p=
10(p-0.2p)/10=
(10p-2p)/10=
8p/10=0.8p
<u>p-0.2p and 0.8p ==> D and B ==> Option 3</u>
It makes a 90 degree angle.
Answer:
60 people left each year so -60
Step-by-step explanation:
-300 is the total population change over the past 5 years
The population decreased.
Divide 300/5 to find the amount of people who left each year
300/5= 60
60 people left each year.
The change in the towns population is (-60)
