We are to find P(A' ∩ B).

A' indicates Compliment of A.

Since A and B are independent events, we can use the formula:

P(A' ∩ B) = P(A') x P(B)

P(A') = 1 - P(A) = 1 - 0.4 = 0.6

So,

P(A' ∩ B) = 0.6 x 0.9 = 0.54

So, option A gives the correct answer

Which of the following is the equation of the line that is parallel to y=35x+8 y = 3 5 x + 8 and goes through point (-10,4)?

xeze [42]

Slope-intercept form of a line is y=mx+b.

Where m= slope and b= y-intercept.

First step is to compare the given equation y=35x+8 with the above equation to get the value of m.

After comparing the two equations we will get m=35.

Slope of paralle lines always equal which means slope of a line which is parallel to the above line will also be 35.

Now the line is passing through (-10,4).

Point slope form of a line is :

$y-y_{1} =m(x-x_{1} )$

Next step is to plug in m=35, x1=-10 and y1=4 in the above equation. So,

y-4=35(x-(-10)

y-4=35(x+10)

y-4=35x+350

y=35x+350+4

y=35x+354.

So, the equation of the line is y=35x+354.
