Answer:
I hope this helps :D
Step-by-step explanation:
4
It can be done a lot easier: instead of calculating the probability of one head, two heads, three heads, ... one just needs to calculate the probability of no heads: that is simply 0.5
0.5
n
. If you subtract it from 1, you get the probability you want: it's because that's the chance of not no heads, meaning at least one head. So, the formula is: 1−0.5
1
−
0.5
n
More formally: if X is throwing at least one head,
()=1−(¬)
P
(
X
)
=
1
−
P
(
¬
X
)
, where ¬
¬
X
is throwing zero heads.
Consider the equation:

Subtracting '4' from both the sides of the equation, we get as


Squaring on both the sides of the equation, we get


Subtracting '2' from both the sides of the equation, we get

x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.
The correct answer is 'C'
If X = 2, and Y = 4:
2(2) + 3(4) - 2 - (8 + 1) = 5
4 + 12 - 2 - 9 = 5
16 - 2 - 9 = 5
14 - 9 = 5
= 5
(2) + 3(4) - 9 = 5
2 + 12 - 9 = 5
14 - 9 = 5
= 5
So, your answer would be 'C' X + 3Y - 9
Answer:
domain[-5,-3)U(4,3)
range-(4,-4)
Step-by-step explanation
parentheses are used when the circle is open and brackets are used when the circle is filled in, domain is the x axis and range is the y axis
600 is 10 times larger than 60
