Step-by-step explanation:
Given that M is a positive integer, M + 1 is also a positive integer.
Since the difference between them is only 1, they cannot have a common factor above 1.
(For example if M is even, M + 1 must be odd and therefore they do not have a common factor 2 and so on)
Hence we conclude the GCF of M and M + 1 is 1.
Answer:
The probability is:

Step-by-step explanation:
Keep in mind that the probability of getting a head is always the same for each

Therefore the probability of not having a head is:

So if we throw the coin 4 times the probability P of not getting any head is:


Set up ratios of height / shadow length:
8/6 = x/100
Cross multiply
6x = 800
Divide both sides by 6
X = 133.33 feet
The tower is 133.3 feet
P = 2(L + W)
P = 264
W = 54
264 = 2(L + 54)
264 = 2L + 108
264 - 108 = 2L
156 = 2L
156/2 = L
78 <=== Length is 78 yards
