Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.
Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2
So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2
Then you would solve it and you should end up with 11.6619
Answer is 100/55 = n/620 Reasoning is the percentage has a max of 100 and you do is 100/55 = to the number for N/620
I don't know if this is the ans.u2+14-28=0
Due to a negative value of P(X = x), it is found that the following is not a probability distribution.
---------------------
A sequence (x, P(X = x)) is a probability distribution if:
- The sum of all values of P(X = x) equals 1.
- There is no negative values of P(X = x).
In this problem, P(X = 2) is negative, thus, it is not a probability distribution.
