(a) The probability that an automobile being filled with gasoline will also need an oil change is 0.35; the probability that it

cricket20 [7]

Answer:

0.714 ; 0.556 ; (A1 n A2 n A3) = 0

Step-by-step explanation:

Given that :

P(oil) = 0.35

P(filter) = 0.45

P(oil n filter) = 0.25

P(filter | Oil) = P(oil n filter) / P(oil)

P(filter | Oil) = 0.25 / 0.35 = 0.714

11)

P(Oil | filter) = P(oil n filter) / P(filter)

P(Oil | filter ) = 0.25 / 0.45 = 0.556

Number of red aces = 2

Queen or king = 4 + 4 = 8

Number on card greater than 3 and less than 8 = {4,5,6,7} = 4 card ; for 4 suits = 4 * 4 = 16

Total number of cards in deck = 52

Choosing without replacement :

Hence,

A1 = 2 / 52

A2 = 8 / 51

A3 = 16 / 50

(A1 n A2 n A3) ;this means card common to all three events.

However, (A1 n A2 n A3) = 0 because ;

1.) No red ace card is greater than 3 and less than 8.

11.) An ace card can neither be a king nor a queen

4. Given the line 7x + 6y = 5, do the following.

Annette [7]

Answer:

a- Slope-intercept form (y = $\frac{-7 x}{6\\}$ + $\frac{5}{6}$ ) ::=> 1

b- Slope of Line = m = $\frac{-7}{6}$ : From Equation 1

Step-by-step explanation:

a- We have following equation:

7x + 6y = 5

Here if we re-arrange for y:

6y = 5 -7x :: Compare it with y = mx + b

y = $\frac{-7 x}{6\\}$ + $\frac{5}{6}$

b-Compare y = mx + b and y = $\frac{-7 x}{6\\}$ + $\frac{5}{6}$

m= -7/6 and Slope of lines parallel to the given line is shown in the equation
