Answer:
Step-by-step explanation:
If ' n ' is the cardinal number of a set, the number of subsets of a given set can be obtained by using the formula 2ⁿ
Given,
N = { 1 , 42 , 65 , 12 , 31 , 27 }
where n ( total number of elements ) = 6
So, the number of possible subsets of set N :
= 2ⁿ
= 2⁶
= 2 × 2 × 2 × 2 × 2 × 2
= 64

Step-by-step explanation:
Given:
Solve it. First, express y in terms of x from the second equation:
Substitute it into the first equation:
Apply zero product property:
So,
When then
When then
We get two solutions: (5,-4) and (-5,6)
Answer:
D.
Step-by-step explanation:
Solution,
Two dice are thrown.
So we have to find out the total number of outcomes.
The total number of outcomes =
We have to find out the probability of outcomes that add up to 9.
So, Possible outcomes are;
<u></u>
The total number of possible outcomes =
Now, according to the formula of probability,
Hence the correct option is D)4/36.
