Based on the lengths of the given triangles and the length of segment BD, the length of segment AD is 22.20.
<h3>What is the length of segment AD?</h3>
The triangle ABC is a right angled triangle with segment AB being the hypothenuse.
We can therefore find this length using the Pythagoras Rule:
Hypothenuse ² = a² + b²
Hypothenuse ² = 28.6² + 23.2²
Hypothenuse ² = 1,356.20
Hypothenuse = √1,356.20
= 36.83
Length of AD:
= AB - BD
= 36.83 - 14.60
= 22.2

Between the probability of union and intersection, it's not clear what you're supposed to compute. (I would guess it's the probability of union.) But we do know that

For parts (a) and (b), you're given everything you need to determine

.
For part (c), if

and

are mutually exclusive, then

, so

. If the given probability is

, then you can find

. But if this given probability is for the intersection, finding

is impossible.
For part (d), if

and

are independent, then

.
Answer:
y=2/3x+4.3
Step-by-step explanation:
y=mx+c
(5-3)/(1--2)
2/3= gradient
y=2/3x +c
5=2/3(1)+c
-2/3
4.3=c
Answer:
sqrt239
Step-by-step explanation:
Using the pythagoream thereom, we know that a^2+b^2=c^2.
so x^2+17=256
That makes x the square root of 239.
$54.80 is the correct answer
