Lines M and N are parallel. Find the value of x.

AVprozaik [17]

Answer: 42

Step-by-step explanation:

First of all, referencing the data given, lines M and N are definitely not parallel, and intersect.

However, considering the system included in the question, you may solve for x in a plethora of ways, assuming both expressions are complete, and equal to f(x).

4x - 24 = y

3x + 18 = y

Using the elimination method, consolidate these equations into:

x - 42 = 0

x = 42

Hope it helps :) and post a more complete question if this isn't the answer you were looking for.

To the nearest tenth, what is the value of P(C|Y)? 0.4 0.5 0.7 0.8

erica [24]

Answer:

P(C|Y) = 0.5.

Step-by-step explanation:

We are given the following table below;

X Y Z Total

A 32 10 28 70

B 6 5 25 36

C 18 15 7 40

Total 56 30 60 146

Now, we have to find the probability of P(C/Y).

As we know that the conditional probability formula of P(A/B) is given by;

P(A/B) = $\frac{P(A \bigcap B)}{P(B)}$

So, according to our question;

P(C/Y) = $\frac{P(C \bigcap Y)}{P(Y)}$

Here, P(Y) = $\frac{30}{146}$ and P(C $\bigcap$ Y) = $\frac{15}{146}$ {by seeing third row and second column}

Hence, P(C/Y) = $\frac{\frac{15}{146} }{\frac{30}{146} }$

= $\frac{15}{30}$ = 0.5.
