Answer:
Step-by-step explanation:
Let S be the sample space, n(S) = 60
a) Let A be the event that the selected athlete uses
s less than a minute, n(A) = 59
The probability that a randomly selected athlete uses less a minute, P(A) = n(A)/n(S) = 59/60 = 0.9833
b) 1 - 0.9833 = 0.0167
c) 1 - 1 = 0
3 water bottles.
1 liter is the same as 1,000 milliliters. So, the water jug can hold 6,000 milliliters of liquid.
Simple divide 6,000/2,000, which is the same as 6/2, to get 3. So, the water jug needs 3 water bottles of liquid to fill it.

Given : (8 + i)(2 + 7i)
⇒ (8 × 2) + (8 × 7i) + (i × 2) + (i × 7i)
⇒ 16 + 56i + 2i + 7i²
We know that i² = -1
⇒ 16 + 58i + 7(-1)
⇒ 16 + 58i - 7
⇒ 9 + 58i

Answer:
Step-by-step explanation:
hello :
5x-y=7....(*)
4x+8y=-12...(**)
multiply (*) by 8 : 40x-8y =56 ...(***)
add(**) and (***) : 44x = 44 so : x = 1
put this value in (*) : 5(1)-y = 7
y = 5-7 = -2
