Answer:
Both answer choices are irrational
Step-by-step explanation:
Irrational means the number cannot be over a fraction or repeating so they are both irrational

Answer:
y-7= -1/5x
Step-by-step explanation:
general formula (y-y1)= m(x-x1)
m is the slope and in this case m=-1/5
(x1, y1) is a point on thhe line in this case is (0, 7) because f(x)=y
substitute your given in the equation
(y-7) = -1/5(x-0)
y-7= -1/5x
This is a binomial distribution where 80% of flights arrive on time (p = 0.8) and 20% do not (q = 1 - 0.8 = 0.2). Then the probability that exactly 2 flights arrive late follows the formula:
(nCr)(p^r)(q^(n-r)), where n = 16 (total # of flights), r = 14 (flights that arrive on time)
(16C14)(0.8^14)(0.2^2) = 0.2111
a=2c+40 z=2c+142 x=2c+165 b=c+82 y=c-20
14+2c+40+2c+142+2c+165+c+82+c-20=1203
c=86 2/3
y=66 2/3
b=168 2/3
x=338 1/3
z=315 1/3
a=213 1/3
