f(6) = 1+2+4+8+16+32 = 63
f(7) = 63 + 64 = 127
This is a geometric sequence where r the common ratio = 2.
f(n) = a1 * (r^n - 1) / (r - 1)
here a1 = 1 and r = 2 so
f(n) = (2^n - 1) / (2 -1)
= 2^n - 1.
When n = 64 ( the last square on the chess board)
f(n) = 2^64 - 1 = 2^64 ( I think we can neglect the 1!!)
That is the total number of grains of rice.
In tons of rice this is 2^64 / (25,000 * 2000)
= 3.689349 * 10^11 tons approximately.
So for each person the amount of rice would be 3.689349 * 10^11 / 6 * 10^9
= 61.5 tons approx. (Answer).
45 because 1.5*30 minutes in a half hour is 45 gallons of water
Answer:
4.45
Step-by-step explanation:
Given:
Height of basketball player is 206 cm.
z-score = 4.45
z-score is a numerical value that tells the number of standard deviations a particular data value is away from the mean. A positive (negative) z-score indicates that the number of standard deviations a particular data value is above (below) the mean.
In this case, it is given that the z-score is 4.45 (positive).
Hence, it could be concluded that the player's height is 4.45 standard deviation(s) above the mean.
