Answer:
40
Step-by-step explanation:
Given that
Total number of adults, U = 285
Number of plane travellers, P = 75
Number of train travellers, T = 55
To find the number of people that didn't travel by any means of transportation listed in the question, then we say
Total number of adults minus number people who traveled by plane or train minus number of people who traveled by bus but not by plane or train.
This means that number of people who didn't travel by any of the three means of transportation, N =
N = U - pt - b
N = 285 - 215 - 30
N = 40
Therefore, the total number needed is 40
Answer:
y=78
Step-by-step explanation:
y=13(x-4) 2-4
y=(13-52) -2
y=(-24+104)
y=78
Answer:
x>
.
x>\frac{53}{6}
Step-by-step explanation:
12x>140−34
2 Simplify 140-34140−34 to 106106.
12x>106
12x>106
3 Divide both sides by 1212.
x>\frac{106}{12}
Answer:
Probability of each situation is 1/3 .
Step-by-step explanation:
There are 3 possibilities
1- Train will arrive early
2- Train will arrive on time
3- Train will arrive late
Formula for Probability of event a is = n(a)/Sum of events
In this case sum of events = 3
So
Probability of early arrival = 1/3
Probability of on time arrival = 1/3
Probability of late arrival = 1/3
Answer:
2/8
Step-by-step explanation:
There are 2 green marbles.
In all, there are 8 marbles.
So, the probability is 2/8.
