The Dowers make pumpkin pie. If each person wants three slices of pie, and each pie is Cut into 9 slices, how many pies do they

Mrac [35]

The Dowers need to make 5 pies for 15 people.

Step-by-step explanation:

Given,

1 person = 3 slices of pie

15 persons = 15*3 = 45 slices of pie

It is also given that;

9 slices of pie = 1 whole pie

1 slice of pie = $\frac{1}{9}\ pie$

45 slices of pie = $\frac{1}{9}*45$

45 slices of pie = 5 whole pies

The Dowers need to make 5 pies for 15 people.

Mark tosses a coin 25 times. What is the probability that it lands on heads exactly seven times?

mezya [45]

Answer:

1.43%

Step-by-step explanation:

we have that we can solve it by means of binomial, in this case m = 25. Also the probability of head is 50%. we need to know when it falls 7 times, therefore x = 7

the formula is:

P (x) = mCx * p ^ x * q ^ (m-x)

we know that p is 0.5 therefore q is equal to 0.5, replacing:

P (7) = 25C7 * 0.5 ^ 7 * 0.5 ^ (25-7)

P (7) = 25! / (7! * (25-7)!) * 0.5 ^ 7 * 0.5 ^ (25-7)

P = 0.0143

that is, the probability is 1.43%
