First you have to find a common denominator which would be 24.
5/6 = 20/24
7/8 = 21/24
5/8 = 15/24
So your final answer would be 7 over 8.
3x + 4(3x+17) = 8
3x + 12x + 68 = 8
15x = - 60
x = - 4
i am a mathematics teacher. if anything to ask please pm me
Key word: sum
twice a number = 2n
Sum of that and 15 = 2n + 15
is = equals
Answer: 2n + 15 = 9
Answer:
36% is the joint probability that a flight arrives late because of weather and ground operations
Step-by-step explanation:
Given
% of flight late because of weather = 0.75
% of flight late because of ground operation = 0.35
% of flight late because of both weather and ground operation = 0.10
The probability of joint probability that a flight arrives late because of weather and ground operations is equal to
p (A and B) + {P(A) * P(B)}
0.10 + (0.75 * 0.35)
0.36
or 36%
