Answer:

12 weeks.

Step-by-step explanation:

Amanda starts with $2000 and is getting $150 per week which means that we can make the expression:

2000-150n=200

The expression is equal to 200 because is the limit where we can arrive to avoid the fee, then the n is the number of weeks that we are looking for:

150n=2000-200\\n=\frac{1800}{200}\\n=12

n=12 weeks

expeople1 [14]

Answer:

P(X=2)=0.04129

Step-by-step explanation:

-This is a binomial probability problem whose function is expressed as;

P(X=x)={n\choose x}p^x(1-p){n-x}

-Given that p=0.6, n=8 , the probability that among the students in the sample exactly two are female is calculated as:

P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X=2)={8\choose2}0.6^2(1-0.6)^6\\\\=0.04129

Hence, the probability of exactly two females is 0.04129
