x = 27

Step-by-step explanation:

Since l, m, and n are cut across by the two transversal lines, therefore, the transversal lines are cut off proportionally.

This implies that:

6/x = 10/45

Cross multiply

x*10 = 45*6

10x = 270

10x/10 = 270/10

x = 27

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

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;
