At 6 am, an online company has sold 120 items that day. if the company sells an average of 30 items per hour for the remainder of the day , write an expression to represent the number of items that were sold n after 6 am

An expression that represents the amount of items sold will be: Items = 30 x h, where 'h' represents the number of hours.

Step-by-step explanation:

At 6am an online company has sold 120 items. The company sells 30 items per hour, and you have to find the items sold for the remainder of the day.

From 6am to 12am there are 18 hours. Given that the company sells 30 items per hour, the amount of items sold for the remainder of the day will be:

30 x 18 hours = 540

the amount of items sold for the remainder of the day will be 540.

An expression that represents the amount of items sold will be:

Items = 30 x h, where 'h' represents the number of hours.

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;
