In a school machine shop, 60% of all machine breakdowns occur on lathes and 15% occur on drill presses. Let E denote the event t

RSB [31]

Answer:

A. P(EC) = 0.4

B. P(E∪E) = 0.75

C. P(EC ∩ FC) = 0.25

Step-by-step explanation:

Let us calculate -:

we are given with - P(E) = 60 and P(F) =.15,

Thus , (a) $P(E^C)=1-P(E)$

$=1-0.6$

$=0.4$

(b) P(E∪F) = P(E) + P(F)

= 0.60 + 0.15

= 0.75

(c) $P(E^C$ ∩ $F^C)$ $=1-P(E$ ∪ $F)$

$=1-0.75$

= $0.25$

Hence , the answers are -A. P(EC) = 0.4 , B. P(E∪E) = 0.75 , C. P(EC ∩ FC) = 0.25.

Please help me on #7

No, the number of children are not proportional. In one household where there is 1 parent, there are 3 children, and in another household where there is 1 parent, there are 5 children. The numbers are not consistent, and therefore not proportional.

At one of New York’s traffic signals, if more than 17 cars are held up at the intersection, a traffic officer will intervene and

olga55 [171]

The random variable is the number of cars held up at the intersection.

A random variable is one whose value is aleatory, then you can not know anticipatedly the outcome for sure. In this case, the number of cars held up at the intersection may be different at any time inside the range given and you cannot know the number of cars that there will be in a future moment.

The point (2, 1) is on the line given by which equation below? A. y=x+1 B. y = 2x C y = 1/2x D. Y = -2x

Murrr4er [49]

Answer:

C. y = 1/2x

Step-by-step explanation:

We can check to see which of the equations passes through (2,1) by substituting the point's x and y values into the options, then checking to see if the result is a true statement.

Let's try this with option C, $y = \frac{1}{2} x$ . To substitute the x and y values of (2,1) into the equation, substitute 2 for $x$ and 1 for $y$ . Then, solve:

$y = \frac{1}{2} x\\\\1 = \frac{1}{2} (2)\\1 = 1$

1 does equal 1, so the result is a true statement. Option C is the answer.
