You would multiply both 2x and -8 by 5. The answer would be 10x-40.
Answer:
option D
Step-by-step explanation:
we have a right triangle
we know
c^2=a^2+b^2
c=hypotenuse
c=52 cm
a=48 cm
b= 20 cm
we substitute in the equation c^2=a^a+b^2
so we have
52^2=48^2+20^2
52= sqrt(48^2+20^2)
52= sqrt(2304+400)
52= sqrt(2704)
52cm=52cm
so c=52 cm
so the option D is the correct answer
Answer:
0.59375
Step-by-step explanation:
In a uniform distribution the probability that the time t is greater than any given value, X, is:

In this problem, the limits of the distribution are a = 0 and b = 8 minutes.
For X =3.25 minutes:

The probability that a randomly selected passenger has a waiting time greater than 3.25 minutes is 0.59375.
150 because if you take 180 and subtract 30 u get 150
