A man and a woman agree to meet at a certain location about 12:30 pm. If the man arrives at a time uniformly distributed between
dimaraw [331]

Explanation.

The question is incomplete. However, the complete part of the question simply states that:  What is the probability  that the man arrives first?

Answer:

Therefore, we can say that the probability that the man will arrive first is half that is 1/2 while the probability that no one will wait more than five times is 1/6

Step-by-step explanation:

We assume the man and the woman arrive at 12:X and 12:Y  respectively (1:00 is 12:60). Also, the space of X and Y are [15, 45]  and [0, 60] respectively, and fₓ (x) ≡ 1 / (45 − 15) = 1/30, fy (y) ≡  1 / (60 − 0) = 1 / 60.

So the joint pdf of X and Y is

f(x, y) = 1 / 30 x 1 / 60

         = 1 / 1800

where ( x , y ) ∈ [15, 45] × [0, 60].

Consequentially,

P(| X − Y | ≤ 5) = ∫ Iim (45)(15) ∫ lim (x+5)(x-5) f (x,y)dydx

= 1 / 1800  ∫ Iim (45)(15) y | ₓ₋₅ˣ⁺⁵ dx

= 30 x 10 / 1800

300 / 1800

= 1 / 6

Hence,

P( X < Y ) = ∫ Iim (45)(15) ∫ lim (60)(x) f (x,y) dydx

= 1 / 1800  ∫ Iim (45)(15) y | ⁶⁰ₓ dx

=  1 / 1800 ∫ Iim (45)(15) ( 60 - x ) dx

= 60 x − x  ²/2 ÷ 1800 ║⁴⁵₁₅

= 1 / 2

HELPPPPPPPPP WITH THESE GRAPH! YOU'LL GET BRAINLIEST IF YOU'RE CORRECT! ALSO... THERE'S 20 POINTS!
lara [203]

<u>Given</u>:

Four coordinates lying on the 3rd quadrant of the Cartesian plane are as follows: \:

  • C' = (–6, –5)
  • D' = (–6, –3)
  • E' = (–4, –3)
  • F' = (–4, –5)

<u>Translation</u>:

Since you've been asked to translate the coordinates of the vertices 2 units right and 8 units up, you'll need to add 2 to its x-coordinate and 8 to its y-coordinate.

C'(–6, –5)

ㅤㅤ= C'(–6 + 2, –5 + 8)

ㅤㅤ= C'(–4, 3)

D'(–6, –3)

ㅤㅤ= D'(–6 + 2, –3 + 8)

ㅤㅤ= D'(–4, 5)

E'(–4, –3)

ㅤㅤ= E'(–4 + 2, –3 + 8)

ㅤㅤ= E'(–2, 5)

F'(–4, –5)

ㅤㅤ= F'(–4 + 2, –5 + 8)

ㅤㅤ= F'(–2, 3)

<u>Final </u><u>answer</u>:

  • C' = (–4, 3)
  • D' = (–4, 5)
  • E' = (–2, 5)
  • F' = (–2, 3)

HELP FAST SO CONFUSED<br><br> Find the area of the shaded sector. Leave your answer in terms of π.
ddd [48]
Total area: pi*9^2 = 81pi

Shaded area = Total area / 3, because 120/360 = 1/3

So Shaded area = 81pi/3 = 27pi
