Larry travels 60 miles per hour going to a friend’s house and 50 miles per hour coming back, using the same road. he drove a tot

yaroslaw [1]

V1=60. 60×t1=50×t2=S
V2=50
T=t1+t2=5. 5-t2=t1
60×(5-t2)=50×t2
300-60×t2=50×t2
300=50×t2+60×t2
300=t2×(50+60)
300=t2×110
300/110=t2

S=50×300/110

Say a business found that 98.3% of soda cans at a production facility in California are filled correctly. The company chooses 10

Shtirlitz [24]

Answer:

The events must be independent.

Step-by-step explanation:

The only assumption that must be made is that the events are independent. That is, the amount of soda in a given can does not depend on the amount of soda of any previous can filled at the same facility.

If this assumption holds, then the probability of finding exactly k cans of soda filled correctly would be

$\displaystyle\binom{100}{k}(0.983)^k(1-0.983)^{100-k}$

where

$\displaystyle\binom{100}{k}=\displaystyle\frac{100!}{k!(n-k)!}$

are combinations of 100 elements taken k at a time.
