Correct formula is y = kx, where k is the "constant of proportionality."
If y = 9 when x = 2, then 9 = k(2), or k = 9/2.
Then y = (9/2)x.
If x = 3, y = (9/2)(3) = 27/2 (answer)
5x - 3y - z
By hypothesis, x = -2, y = 2 and z = -3.
So you all need to do is replace each letter by its value and do the calculus:
5x - 3y - z = 5*(-2) - 3(2) - (-3)
= -10 - 6 + 3=
=-16 + 3
= -13
So when x = -2, y = 2 and z = -3
5x - 3y - z = -13 (answer d)
Hope this helps! :)
Answer:
The probability that they each win six games is 0.225.
Step-by-step explanation:
Given : A computer chess game and a human chess champion are evenly matched. They play twelve games.
To find : The probability that they each win six games?
Solution :
Applying binomial distribution,
Here n=12 and p=0.5

The probability that they each win six games is k=6.




Therefore, The probability that they each win six games is 0.225.
