A portion of the circumference is called an arc.
Answer:
2 (4x - 1) + 6 = 8x + 4 = 4(2x+1)
Step-by-step explanation:
2 (4x - 1) + 6
= (2*4x + 2*-1) + 6
= 8x - 2 + 6
= 8x + 4
= 4/(2x+1)
So, in 240 miles can be made by 2 hours.
Do this equation:
240 × 2 = 480 / 4 hours.
You cannot do 3 because it won't fit another 240 miles.
Next, subtract the 480 miles from 600 miles.
600 - 480 = 120
Also, if you would've divided by 2 hours.
240 ÷ 2 = 120 / 1 hour
Add the hours.
4 + 1 = 5 hours
It takes 5 hours to travel 600 miles by the small plane.
Answer:
a) P = 0.125
b) It is not necessarily true
Step-by-step explanation:
a. If the coin was fair, the probability of obtaining head would be 0.5, and each launch of the coin would be an independent event.
Remember that if two events A and B are independent, then:
P(A∩B) = P(A)P(B)
Therefore, the probability that Caitlin would get heads on all three flips is:
P(A∩A∩A) = P(A)P(A)P(A) = 0.5*0.5*0.5 = 0.125
b) It is not necessarily true, because there exist a probability associated to this event and it means that this situation can occur although the coin was fair.
