At an ice cream shop, 2 of the last 14 cones sold had cookie dough ice cream. what is the experimental probability that the next cone sold will have cookie dough ice cream?

3x + 4y -25 =0 represents the amount of change sianna should recieve

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;

my guess would be b and d, but i didn’t actually get out the pen and paper. lol

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
