Answer:
Mean number of births = 12.02 births per day.
P(X=14) = 0.0908=9.08%
Not likely
Step-by-step explanation:
Mean number of births (λ):
Assuming a Poisson distribution, the probability of X = 14 successes (births on a single day) is determined by:
The probability that there are exactly 14 births in a day is 9.08%, which is not likely.
Answer:
tip: $7.50
total: $57.50
Step-by-step explanation:
you change the 15% into a decimal by moving the the decimal point 2 spots to the left so now you have .15
next do .15 * 50 to get 7.5, which is the tip
now to find the total, add 7.5 + 50 to get 57.5
Um I think it is 2,1 count over 2 then go up1
Answer:
And that represent the instantaneous velocity at a given time t.
And then we just need to replace t =2 in order to find the instantaneous velocity and we got:
Step-by-step explanation:
For this case we have the position function s(t) given by:
And we can calculate the instanteneous velocity with the first derivate respect to the time, like this:
And if we take the derivate we got:
And that represent the instantaneous velocity at a given time t.
And then we just need to replace t =2 in order to find the instantaneous velocity and we got:
