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.

Please help with the 4th one

The whole field is square, and its total area is 25 acres. 
It's divided up into 25 little sections. 
Each little section is a square, and its area is 1 acre. 

So the whole thing looks like a square tray with 25 little square blocks in it.
The blocks are in 5 rows, and there are 5 blocks in each row.

There are 16 blocks around the edge of the square tray, and 9 in the middle
that don't touch the edge.

Every block costs $1,200 to start out.  But the ones around the edge are
more expensive.  Anything on the edge costs an extra $150 for each side
of the little block that touches the edge.

Most of the 16 little blocks around the outside have only 1 side that touches
the edge.  But the ones in the <em>corners</em> of the tray have 2 sides along the edge.

You may want to have a look at the picture I attached.

That should be plenty to put you in a position to work out the costs.

Determine whether the two triangles are similar and, if they are similar, state a reason.
aleksley [76]

Answer:

Step-by-step explanation:

By triangle sum theorem,

Sum of interior angles of a triangle is 180°.

Therefore, measure of third angle in the larger triangle = 180° - (35° + 120°) = 25°

Similarly, measure of third angle in the smaller triangle = 180° - (25° + 120°)

= 35°

Since, measure of interior angles of larger triangle is equal to the measure of smaller triangle,

Both the triangles will be similar by AA property of similarity.
