There are 2,000 players in a basketball tournament. In each round, half of the players are eliminated. Which function can be used to find the number of players remaining in the tournament at the end of x rounds?

Step-by-step explanation:

Left = 2000 * (1/2)^x

Try it.

x = 1

Left = 2000 * (1/2)^1

left = 2000  * 1/2

left = 1000

x = 3

left = 2000 (1/2)^3

left = 2000 (1/8)

left = 250

x = 4

left = 2000 * (1/16)

left = 125

from her on the function does not work accurately. You have to modify the algorithm.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
