3 (1-7) = 3*1+3*-7
I really just used the distributive property for this.
For a number to be divisible by 14 it needs to be both divisible by 7 and 2 which are factors of 14. Every time you have a number (x) to check if it is divisible by some larger number you find the factor of that larger number and check is the x divisible by both.
Answer: it cannot be divisible by 14.
Answer:64
Step-by-step explanation:
Answer:
0.5
Step-by-step explanation:
From the given data, to find out the probability of the train being late we employ the following method:
Probability of train being late = how many times the train was late / total train trips
Probability of train being late = 5 / 10 = 0.5
Since this is the probability of the train being late, the probability of it being on time will be 1 - (prob. of train being late)
This is:
Probability of train being on time = 1 - 0.5 = 0.5
