Answer:
x = 10
Step-by-step explanation:
supplementary angles
y + 6x - 15 = 180
triangle
(2x+18) + (2x-13) + y = 180
simplify the above to get these equations
y + 6x = 195
y + 4x = 175
solve for system of equations by subtracting the second from the first and you get
2x = 20
x = 10 degrees
please give a like and brainly :)
Answer:
0.6535
Step-by-step explanation:
Given that during a one-hour period twenty-five customers buy gasoline at this station.
Let X be the no of persons out of these 25 who pay by cash.
X has two outcomes and each trial is independent of other.
Hence X is binomial (n=25, p=0.40)
Required probability
=
=0.6535
