Answer:

the tree will be 11.04 feet tall

Step-by-step explanation:

4 x 0.22 (22%) = 0.88

every year it grows 0.88 foot.

0.88 x 8 = 7.04

4 + 7.04 = 11.04 feet tall

sorry if this is wrong!

The table below shows the number of hours some business people in two states spend in meetings each week: State A 21 23 24 22 24
Lera25 [3.4K]
State A:
21,22,22,23,23,23,24,24,25

minimum = 21
Q1 = 22
Q2(median) = 23
Q3 = 24
maximum = 25
IQR = Q3 - Q1 = 24 - 22 = 2

state B:
20,20,21,22,23,23,24,46,50
minimum = 20
Q1 = (20 + 21)/2 = 20.5
Q2(median) = 23
Q3 = (24 + 46)/2 = 35
maximum = 50
IQR = 35 - 20.5 = 14.5

I do not believe they are symmetrical....I think state B is skewed to the right

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
