Speed=distance traveled/time of the travel=78/2=39 mph
Answer:
2/3
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that there are 10 balls of which 3 green, 3 red, and the rest yellow
Number of yellow balls = 10 - 3 - 3 = 4
Probability of picking a;
Green ball = 3/10
Red ball = 3/10
Yellow ball = 4/10
If two balls are picked without replacement, the probability that one is at least yellow will be
YR RY YG GY YY
= 4/10*3/9 + 3/10*4/9 + 4/10*3/9 + 3/10*4/9 + 4/10*3/9
=12/90 *5
= 2/3
I'm not sure what you're really asking but 6 and 9's LCM is 18
- 3 ( x - 1 ) = 18
- or, 3x - 3 = 18
- or, 3x = 18 - 3
- or, 3x = 15
- or, x = 15 ÷ 3
- or, x = 5
