Answer:

$P(r n L) = 0.12$

$P(L) = 0.225$

$P(\= r | L) = 0.4667$

Step-by-step explanation:

The chance that it will rain is $P(r ) = 0.30$

The chance that it does not rain is $P(\= r ) = 1 - P(r )$

$P(\= r ) = 1 -0.30$

$P(\= r ) = 0.70$

The probability that the bus run late if it rains is $P(L | r) = 0.4$

The probability that the bus run late if it does not rain is $P(L | \= r) = 0.15$

Generally the probability that it will rain and the bus will be late is mathematically represented as

$P(r n L) = P(L | r) * P(r)$

=> $P(r n L) = 0.4 * 0.30$

=> $P(r n L) = 0.12$

Generally the probability that the bus will be late is mathematically represented as

$P(L) = P(r) * P(L|r) + P(L | \= r) * P(\= r)$

=> $P(L) = 0.30 * 0.4 +0.15*0.70$

=> $P(L) = 0.225$

Generally given that the bus ran late, the probability that the bus it was not raining is mathematically represented as

$P(\= r | L) = 1- P(r | L )$

Here $P(r | L ) = \frac{P(r n L)}{P(L)}$

=> $P(r | L ) = \frac{0.12}{0.225}$

=> $P(r | L ) = 0.533$

$P(\= r | L) = 1- 0.533$

=> $P(\= r | L) = 0.467$

Find x <br><br> please help me out will mark you brainliest

Artemon [7]

Answer:

38+31+43+x=180

Step 1: Simplify both sides of the equation.

38+31+43+x=180

(x)+(38+31+43)=180(Combine Like Terms)

x+112=180

Step 2: Subtract 112 from both sides.

x+112−112=180−112

x=68

Questions 4 and 5 refer to the following:

Damm [24]

Answer:

Step-by-step explanation:

Parallel lines are lines that never meet, from the question in the attachment above, the two lines that cannot meet are lines 'a' and 'b' and lines 'c' and 'd'

4. Question four is then lines b and a which is option B

Perpendicular lines are lines in which the angle between them is right angle (90 degrees). Which are 'a' and 'c', 'a' and 'd', 'b' and 'c', 'b' and 'd'

5. Question 5 is therefore 'a' and 'c' which is option D
