2/10 is a fraction
The simplest form is 1/5
The probability that no more than 4 vehicles will change lanes is 50.71%.
Since the probability that a vehicle will change lanes while making a turn is 55%, supposing a random sample of 7 vehicles are observed making turns at a busy intersection, to find the probability that no more than 4 vehicles will change lanes while making the turn, the following calculation must be performed:
- ((0.55 x 4) + (0.45 x 3)) / 7 = X
- 0.5071 = X
Therefore, the probability that no more than 4 vehicles will change lanes is 50.71%.

Answer: r = 16.55 ft
Step-by-step explanation: C=2πr
r=C/2π = 104/2 x π ≈ 16.55211ft
Answer:
At 5:15 PM , they will ring together.
Step-by-step explanation:
We have been given that first bell rings every 15 minutes and second bell rings at every 25 minutes.
In order to find when both will ring together again, we can find the LCM of these two numbers.
15 = 3 × 5
25 = 5 × 5
Therefore, LCM of these two numbers is
LCM = 5 × 5× 3
LCM = 75
Hence, 75 minutes = 75/60 = 5/4 hours
Therefore, at 5:15 PM , they will ring together.
