If4 times the reciprocal of a number is 3 more than 5/2 times the reciprocal of that number find the number show your work

1)

4·1/n = 3 + 5/2n

²⁾4/n = ²ⁿ⁾3 + 5/2n

8 = 6n + 5

6n = 8 - 5

6n = 3

n = 3⁽²/6

n = 1/2

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;
