solong [7]

Answer:

13 units

Step-by-step explanation:

Points A(-1, -6) and B(-1, 7) both lie on the vertical line x=-1. That means the distance between them is the difference of their y-coordinates:

By -Ay = 7 -(-6) = 13

Segment AB is 13 units long.

A machine has four components, A, B, C, and D, set up in such a manner that all four parts must work for the machine to work pro

Answer:

0.756

Step-by-step explanation:

It is given that a machine has four components, A, B, C, and D.

$P(A)=P(B)=0.93, P(C)=0.95,P(D)=0.92$

If these components set up in such a manner that all four parts must work for the machine to work properly.

We need to find the probability that the machine works properly. It means we have to find the value of $P(A\cap B\cap C\cap D)$ .

If two events X and Y are independent, then

$P(X\cap Y)=P(X)\times P(Y)$

Assume the probability of one part working does not depend on the functionality of any of the other parts.

$P(A\cap B\cap C\cap D)=P(A)\times P(B)\times P(C)\times P(D)$

Substitute the given values.

$P(A\cap B\cap C\cap D)=0.93\times 0.93\times 0.95\times 0.92$

$P(A\cap B\cap C\cap D)=0.7559226$

$P(A\cap B\cap C\cap D)\approx 0.756$

Therefore, the probability that the machine works properly is 0.756.

a. Solve the formula:

P = 2L + 2W

-2L = -P + 2W

ANSWER FOR A: L = (P/2) - W

b. Substitute the values:

L = (48/2) - 6

Simplify:

L = 24 - 6

L = 18

So the length is 18 feet.

Answer:

y = 3x + 1

Step-by-step explanation:

Since we know the Graph is Parallel to y = 3x + 11, we know that the "mx" portion of the equation is 3x since only the "b" would be different.

Then we just substitute in the point and to find b.

4 = 3(1) + b

b = 1

y = 3x + 1 is the answer
