Let's simplify this equation.
-3(4x-2)-2x
Let's multiply.
-12x+6-2x
Now add like terms.
-14x+6
Well if finding X you get 4,-7 when you simplify the whole equation you get that as well.
Answer:
negative correlation
Step-by-step explanation:
If you were to draw a line of best fit (a line that best expresses the relationship between a group of points), it would have a negative slope.
We are given that the
operation of all circuits is independent with each other, therefore we can use
the multiplication rule for independent events, which states that P (intersection
of A and B) = P(A) * P(B). In this case, we want the intersection of circuit 1 to
be working with the intersection of circuit 2 on and on until circuit 40. That
is, we want every circuit to work with each other. The given probability that
circuit 1 works is .99. The probability that circuit 2 works is still .99 since
this is independent events. And we see that the probability for each of the 40
circuit to work is .99. <span>
So P (intersection of 1 through 40) = .99 * .99 *
.99.....*.99 = (.99)^40 = .6689717586</span>
Answer:
<span>There is a 0.67 probability
(or 67%) that the product will work.</span>
Getting at least a 80% ( B average) is also good still very close to 90
