We need more detail I will help when i get a real question
Because it's decreasing, you use the formula (1-x/100)y with x the percentage decreased which is here 40, and y the number decreased which is here 90
So we get
(1-40/100) * 90
(100/100 - 40/100) * 90
60/100 * 90
5400/100
54
So 90 decreased by 40% is 54
Hope this Helps :)
Answer:
c.12
Step-by-step explanation:
Using the concept of sample space, it is found that the number of possible outcomes in the experiment is given by:
C. 12
The sample space of an experiment is the set that contains all possible outcomes.
In this problem:
For the coin, there are 2 outcomes.
For the dice, there are 6 outcomes.
The coin and the dice are independent, thus, there are 2 x 6 = 12 possible outcomes, which means that the correct option is:
C. 12
Answer:
Step-by-step explanation:
(2r+s)(r-3s)
2r^2-6rs+sr-3s^2
2r^2-5rs-3s^2
