Solve for x: the quantity of x plus 16 all over 3 = 3x

x = 2

Step-by-step explanation:

(x + 16) ÷ 3 = 3 x

x + 16 = 3 × 3 x

x + 16 = 9 x

16 = 8 x

∴ x = 2

what do you need me to answer?

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;
