Hana orders 3 pairs of athletic socks and her friend, charlie, orders 2 pairs of athletic socks. what is the total cost, including shipping for both orders? show your the shipping is $2 per order

The answer would be $64.

Athletic socks = $12

Hana: 3 pairs ($12) = $36 + $2 shipping    = $38

Charlie: 2 pairs ($12) = $24 + $2 shipping = $26

Hana + Charlie = $64 

($38  +   $26 )   = $64

answer: it is d

step-by-step explanation:

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;
