A sandwich store charges $20 to have 3 turkey subs delivered and $26 to have 4 delivered. Which equation would allow you to calculate the price of any number of subs delivered?

Hint: x represents the number of subs

a
6x
b
2 - 6x
c
2 + 6x
d
6x(2)

I think D or A

Step-by-step explanation:

since it goes from 20 to 26 it should be adding 6 and also multiplying by 2

yea

55

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;
