A jar contains 100 coins. If it is very unlikely that you will randomly choose a quarter out of the jar, how many quarters could be in the jar? 10
85
50
35

10

Step-by-step explanation:

As the question says it is very unlikely, 10 must be correct, the other numbers are way higher

its 10

Step-by-step explanation:

hope it helped mate it was the answer to mine :D

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;
