Answer:

x=5, y=1. (5, 1).

Step-by-step explanation:

6x+4y=34

3x-y=14

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

y=3x-14

6x+4(3x-14)=34

6x+12x-56=34

18x=34+56

18x=90

x=90/18

x=5

3(5)-y=14

15-y=14

y=15-14

y=1

Answer:

0.8213

Step-by-step explanation:

-This is a binomial probability problem given by the function:

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

Given that n=21 and p=0.2, the probability that she experience a delay on at least 3 days is calculated as:

$P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 3)=1-P(X$

Hence, the probability that she experience delay on at least 3 days is 0.8213
