Help meee!! ASAP :)))

its c 84

Step-by-step explanation:

Its c because there's a 9 and if you do 12-9=3

so where the 10 is there's 30 cubes things idk what you call them  

so 9 x 6 = 54 so you add 54+30=84

I am 100% right trust meh

I think maybe D or C

english, cause i can’t you

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;
