Houseflies have pretty short lifespans. Males of a certain species have lifespans that are strongly skewed to the
right with a mean of 26 days and a standard deviation of 12 days. A biologist collects a random sample of 9 of
these male houseflies and observes them to calculate the sample mean lifespan.
What is the probability that the mean lifespan from the sample of 9 houseflies 2 is less than 24 days?

c

step-by-step explanation:

i think because what else can be a sample of every member

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

the answer would be 0.54

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
