We would expect 2 people to come down with the flu.
We multiply the probability, 35%, by the number of people exposed, 5:
0.35*5= 1.75 ≈ 2
Answer:
Part A speed=96*2=192km/h
Step-by-step explanation:
Two parts, parts A and part B
Part A=200% more than B
Let part B=x
Part A=200 more than B
=2x
Speed ratio=2:1
Average speed of train=64km/h
Let Part A speed=2x
Part B speed=x
A:B=2:1
Total ratio =3
Speed in the part A can be calculated thus:
Totatl speed= ratio of speed in part A / total ratio
64=2x/3
192=2x
x=96km/h
Part A speed=96*2=192km/h

$26,000 because 25,000 × 0.06 = 1,500.
1,500 + 25,000 + 26,000
let the greatest number be a and remainder be x. And let the whole number result of the division be b, c and d. So we have
ab + x = 2447............(1)
ac + x = 3118...............(2)
ad + x = 6168.............(3)
Subtracting (2) - (1) gives:-
ac - ab = 671
a(c - b) =671
Now 671 = 61 * 11 so 61 could be the value of a
Checking:- 2447 / 61 = 40 remainder 7 , 3118 / 61 = 51 remainder 7
and 6168 / 61 = 101 remainder 7
Answer 61
