Answer:
N=115
Step-by-step explanation:
n=.25(2.5715/.12)^2 =114.8 so round up to 115. Hope that help you
Answer:
It is divisible by 11 and (a + b) !
Step-by-step explanation:
Given a two digit number
, the digits written in reverse order is
.
Note that a two digit number ab = 10a + b.
For example: 24 = 10(2) + 4
Similarly, ba = 10(b) + a
Now, the sum of the numbers ab and ba = 10a + b + 10b + a
= 11a + 11b
= 11(a + b)
Hence, the sum of any two digit number ab and the reverse of the number ba, is divisible by 11 and (a + b).
Hence, proved.
Answer:
401 miles
Step-by-step explanation:
Answer: Our required probability is 0.278.
Step-by-step explanation:
Since we have given that
Probability that a player has a batting average = 0.260
Probability of success = 0.260
Probability of failure = 1-0.260 = 0.74
Number of times at bat = 4
Probability that the player will get two or more hits in his next four times at bat is given by

Hence, our required probability is 0.278.
