Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.
With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.
Answer : It'll take 3.43 hours to do the job if they work at the same rate.
Hope this helps. - M
X subtracted from y means y-x
h+3 subtracted from 6h+1 means 6h+1-(h+3)
din't forgtet to distribute invible -1
6h+1-1(h+3)=
6h+1-h-3=
6h-1h+1-3=
5h-2
Answer:
0.25
Step-by-step explanation:
We are given that Rob created the Venn Diagram shown below which gives us,
The probability of teenagers who like to eat hot dogs = P(HD) = 0.3
The probability of teenagers who like to eat hamburger = P(HB) 0.4
The probability of teenagers who like to eat both = P( HD ∩ HB ) =0.1
The probability of teenagers who like to eat none = 0.2
It is required to find the probability that a teenager eats hot dogs when it is given that he/she eats hamburger i.e. P( HD | HB ).
Now, we know that the probability that an event B occurs given that event A has already occurred is given by,
So,
i.e.
i.e.
Hence, the probability that a teenager eats hot dogs when it is given that he/she eats hamburger is 0.25.
