Answer:

ΔCTA ≅ ΔDRA

Step-by-step explanation:

Triangles CTA and DRA are congruent by ASA postulate. This is because:

∠1 ≅ ∠2 (given)

AC ≅ AR (given)

∠A is the same for both triangles (they are opposite angles)

Then, correspondent angles and sides are congruent, for example, ∠3 ≅ ∠4

What is the slope and y-intercept?

miv72 [106K]

Slope=rise/run
yintercept is where the line crosses the y axis
y=mx+B
m=slope
b=yint
intercept at -3
y=mx-3
pick a point
(5,0)
x=5,y=0
0=m(5)-3
add 3
3=5m
divide 5
3/5=m

slope=3/5
y int=-3

klasskru [66]

Answer:

0.82

Step-by-step explanation:

Given:

<em>A</em> be the event that an Internet user posts photos taken by themselves.

<em>B</em> be the event that an Internet user posts photos taken by themselves.

P(A) = 0.47

P(A) = 0.28

P(A or B) = $P(A\cup B)$ = 0.52

To find:

Conditional probability that an Internet user posts photos given that they post videos.

OR

P(A/B) = ?

Solution:

<em>Formula </em>to be used to find the required conditional probability:

$P(A/B) = \dfrac{P(A \cap B)}{P(B)}$

For this, $P(A \cap B)$ is required.

<em>Formula</em>

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$0.52=0.47+0.28-P(A\cap B)\\\Rightarrow P(A\cap B)=0.23$

Now, the required conditional probability is:

$P(A/B) = \dfrac{P(A \cap B)}{P(B)}\\\Rightarrow P(A/B) = \dfrac{0.23}{0.28}\\\Rightarrow \bold{P(A/B)} = 0.82}$

So, the answer is <em>0.82</em>.
