<h3>Answer: Choice F) 1</h3>

=============================================

Explanation:

x^2+8x+7 factors to (x+1)(x+7)

x^2+4x-21 factors to (x-3)(x+7)

Therefore, the numerator (x^2+8x+7)(x-3) updates to (x+1)(x+7)(x-3)

The denominator (x^2+4x-21)(x+1) updates to (x-3)(x+7)(x+1)

We have three pairs of terms that will cancel between the numerator and denominator. The (x+1) terms pair up and cancel out, so do the (x+7) terms and also the (x-3) terms as well. Everything cancels out. The only thing left is 1 because x/x = 1 where x is nonzero. We can have a more complicated expression replace x to get the same basic idea. This is what I mean by "canceling".

What is the equation of the line????????

IrinaVladis [17]

Answer:

y=1/2x+2

Step-by-step explanation:

The equations come in the form of y=mx+c, where m is the gradient and c is the y-intercept. Looking at the graph we know that the y-intercept is (0,2), so that rules out options B and C.

To find the gradient is a little more tricky, but we can follow the formula:

$\frac{rise}{run}$ , where rise is the vertical value and run is the horizontal value

So we sub in our values:

$\frac{2}{4}$

And simplify:

$\frac{1}{2}$

So now we sub in our new found values into y=mx+c:

y=1/2x+2

according to the general equation for conditional probability of p(an B) = 3/10 and P(B)= 3/5, what is P(A|B)

qaws [65]

The required formula is:
$P(A | B)=\frac{P(A\cap B)}{P(B)}$
Therefore the probability of A given B is:
$P(A|B)=\frac{\frac{3}{10}}{\frac{3}{5}}=\frac{3\times5}{10\times3}=\frac{1}{2}$
