Assume the random variable x has a binomial distribution with the given probability of obtaining a success. Find the following.
borishaifa [10]

Answer:

P(x > 10) = 0.6981.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this question:

n = 14, p = 0.8

P(x>10)

P(x > 10) = P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14)

In which

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 11) = C_{14,11}.(0.8)^{11}.(0.2)^{3} = 0.2501

P(X = 12) = C_{14,12}.(0.8)^{12}.(0.2)^{2} = 0.2501

P(X = 13) = C_{14,13}.(0.8)^{13}.(0.2)^{1} = 0.1539

P(X = 14) = C_{14,14}.(0.8)^{14}.(0.2)^{0} = 0.0440

P(x > 10) = P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) = 0.2501 + 0.2501 + 0.1539 + 0.0440 = 0.6981

So P(x > 10) = 0.6981.

Turkey weigh 7kg how long to cook
ch4aika [34]
If a turkey weighs 7kg or 14lbs, it must have a roasting time of 2 3/4 to 3 hours and a resting time of up to 60 minutes. This weight is good for 8 to 10 servings.

Roasting time is the time it is cooked inside the oven. Resting time is the time the turkey is taken out of the oven but left alone so that the heat inside the turkey will still continue to cook the meat within.

Roasting time varies on the weight of the turkey but the resting time has a maximum of 60 minutes.

3kg - 1 3/4 - 2 hrs.
4kg - 2 - 2 1/4 hrs
5kg - 2 1/4 - 2 1/2 hrs
6kg - 2 1/2 - 2 3/4 hrs
9kg - 3 1/2 - 4 hrs
11kg - 4 1/2 hrs

PLESESSSSS HELPPP
slava [35]
<h3>Answer:  APR = 8.5%</h3>

=================================================

Work Shown:

i = p*r*t

85 = 2000*r*0.5

85 = 1000r

1000r = 85

r = 85/1000

r = 0.085

The APR is 8.5%

---------------

Side note: I used t = 0.5 since 6 months = 6/12 = 1/2 = 0.5 years
