Answer:
0.7553
Step-by-step explanation:
Given that in a busy coffee shop, which is a member of an international chain of coffee shops, 40% of customers order a pastry in addition to their drink.
Hence for 20 customers selected at random during one business day, x the no of customers who did not order a pastry with their drink is binomial since each customer is independent and there are only two outcomes.
X is binomial with n =20 and p = 1-0.4 = 0.60
q = 0.4
the probability that at least 11 of them did not order a pastry with their drink
=
Note that binomial prob
Your answer is 142.86 milliseconds rounded to two decimal places.
As 1 second is equal to 1000 milliseconds, we can write the ratio 7:1000 to represent feet to milliseconds. We can then see that to get 1 foot, we just have to divide 1000 by 7, which gives us 142.8517, or 142.86 to two decimal places.
I hope this helps!

Denote by M the point of intersection of the medians.
Denote also the distance DM by x and the distance QM by y.
From the median properties of triangles we know that
Also,
Since the medians are perpendicular, we deduce that:
Then, since
