There are 48 new houses being built in a neighborhood. Last month, 2/3 of them were sold. This month, 3/4 of the remaining houses were sold. How many houses are left to be sold?

4 houses

Step-by-step explanation:

Last month (48)(2/3) = 32 houses sold

That left 48 - 32 = 16 houses left to sell

This month (16)(3/4) = 12 houses sold

That leaves 16 - 12 = 4 houses left to sell

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;

i think the answer is true
