Answer:
Step-by-step explanation:
Thinking process:
Let the total set be the combination of all the sets as shown
It means that total items = 7 + 14 + 7 + 2
= 30
But the total number of the subsets = 5 + 7+ 2
= 14
Therefore the probability =
=
=
Step-by-step explanation:
Price of Jeans = $78.35
30% coupon = 30% × $78.35 = $23.51
6% sales tax = 6% × $78.35 = $4.70
1% local option tax = 1% × $78.35 = $0.78
Total cost of jeans = $78.35 - $23.51 + $4.70 + $0.78 = $60.32

Step-by-step explanation:
Answer:
Therefore the diameter of the hole is m.
Step-by-step explanation:
Bernoulli's equation,
P₁ = P₂= atmospheric presser
= density
[since P₁ = P₂]
[]
Here
Here g= 9.8 m/s² , h = 10.4 m
The velocity of water that leaves from the hole = m/s
=14.28 m/s.
Given, the rate of flow from the leak is
Let the diameter of the hole be d.
Then the cross section area of the hole is
We know that,
The rate of flow = Cross section area × speed
Therefore the diameter of the hole is m.
