<ABC + <ABC = 180
3x- 9 + 7x - 1 = 180
10x - 10 = 180
10x = 190
x = 19

<ABC = 3x- 9 = 3(19) - 9 = 48

Hey there!

So let's take a look at those two angles... they seem to be supplementary, in other words the two angles add up to 180°.

Now lets set them up as an equation...

∠DBA + ∠ABC = 180                     Now substitute in the value of x into ∠ABC
(7x - 1) + (3x - 9) = 180                     (3x - 9)
(10x - 10) = 180                                 (3*19) - 9
10x = 190                                           57 - 9
x = 19°                                                <u>48</u><u />           <----- That's your answer!

I hope this helps! :D

The problem here takes a brilliant mind to answer this. This problem can easily be answered using programming because we can not then and there push all the possibilities using paper and pen.
The answer is 3816547290. 
Trying all the possibilities starting form 1000000080 (we are sure that the last number should be 0). Then traversing that number until 9999999990. Each traverse, check the number if its divisible to n, so on and so forth.

Maria will take two books with her on a trip. Suppose that the probability that she will like book 1 is .6, the probabilitythats
morpeh [17]

Answer:

0.25 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Probability that like book 1 = 0.6

P(1) = 0.6

Probability that like book 2 = 0.5

P(2) = 0.5

Probability that Maria likes both the books = 0.4

P(1\cap 2) = 0.4

We have to find the conditional probability that she will like book 2 given that she did not like book 1.

Thus, we have to evaluate:

P(2|1') = \dfrac{P(2\cap 1')}{P(1')} = \dfrac{P(2)-P(1\cap 2)}{1-P(1)}\\\\P(2|1') =\dfrac{0.5-0.4}{1-0.6} = 0.25

0.25 is the conditional probability that Maria will like book 2 given that she did not like book 1.
