To determine the solution of the given equation, we can use the quadratic formula which is expressed as:

x = (-b +/- √b^2 - 4ac ) / 2a

where a, b and c are the coefficients of the equation ( ax^2 + bx + c = 0)

USing the formula above we obtain the values:

x = 21
x = 3/4

Hope this answers the question. Have a nice day.

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

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

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

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

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

What is the answer to (4 x 3) х 10º =

mezya [45]

So it's really easy to do this
4 times 2 is 12 and then time 10 degree
=12 times 10 degree
=120 degree
As long any understand that you don't have to change or do anything with the degree and just multiply the numbers .

I hope it helped u
