A is a function

To represent a function each value from the input (x ) can only map to exactly one value in the output (y)

In B

x = 3 → y = 10/ 30 ← 2 values of y

In C

x = - 5 → y = 2/ 3 ← 2 values of y

x = - 10 → y = 4/ 5 ← 2 values of y

In D

x = 20 → y = 25/ 35 ← 2 values of y

A is the only table where each value of x maps to exactly one value in y

Explain why P(A|D) and P(D|A) from the table below are not equal.
trasher [3.6K]

Answer:

The Probability that Event A and  Event D occur is equal to the probability Event A occurs times the probability that Event D occurs, given that A has occurred.


P(A\cap D)=P(A)\cdot P(D/A)

We can find the values of P(A/D) and P(D/A) using the above form formula.

P(D/A)=\frac{P(A\cap D)}{P(A)} ;

P(A/D)=\frac{P(D\cap A)}{P(D)}

From the given table, we have the values of P(A), P(D), P(D\cap A) and P(A\cap D).

Since, Probability=\frac{The number of wanted outcomes }{the number of possible outcomes}

∴P(A)=\frac{8}{17}, P(D)=\frac{10}{17}, P(A\cap D)=\frac{2}{17} and P(D\cap A)=\frac{2}{17}

Now, putting these values in above formula we get,

P(D/A)=\frac{\frac{2}{17}} {\frac{8}{17}}

P(D/A)=\frac{2} {8}=\frac{1}{4}

P(D/A)= \frac{1}{4}.

P(A/D)=\frac{\frac{2}{17}} {\frac{10}{17}}=\frac{2}{10}

P(A/D)=\frac{1}{5}

As, you can see above that the values of P(A|D) and P(D|A) are not equal.

(g o h)(5) = g(h(5))

h(5) = 5-7

plug in h(5) where you have x.

Find the equation of the set of points which are equidistant from the origin and the line x = −2. Sketch this set of points.
lina2011 [118]

Answer:   y² = 8x    

Step-by-step explanation:

The set of points which are equidistant from one point and from a line is a parabola.

In this particular case we have directrix line × = -2 so that means focus must be on the x-axis and with coordenates f (2,0) and p = 2 (the distance between the vertex and the focus with that information we can get the equation

vertex ( 0, 0)     p = 2 the parabola open to the left so is of the form

y² =- 4*p*×           ⇒  y² = 8x
