Answer:

Step-by-step explanation:
According to Reese's model, let the head of the coin represent male, and the tail represents female. The outcome can either be a male or a female.
Total outcome = 2
pr(male) = 
pr(female) = 
Therefore the probability of male equals the probability of females i.e
.
Therefore,
pr(a litter of 5 puppies will be males) =

Answer:
Average speed
= 5 5/6 mph , or
= 5.83 mph (to 2 decimals)
Step-by-step explanation:
Average speed is total distance divided by the total time it takes to cover the given distance.
Since uphill = 5 mph, and downhill = 7 mph, we know the average speed is between 5 and 7 mph.
Let
x = distance uphill, and also distance downhill.
Total distance = 2x miles
Total time = x/5 + x/7 hours = 12x/35 hours
Average speed
= total distance/total time
= 2x / (12x/35) mph
= 70x / 12x
= 5 5/6 mph
= 5.83 mph (to 2 decimals)
