19p-17(-12p-15)

Distribute this please

19p-17(-12p-15)

Step-by-step explanation:

If 19p-17(-12p-15) is the correct expression, we must multiply each -12p and -15 by -17 before doing anything else.  We end up with:

19p + 204p + 255

We can simplify this further by combining the p terms.  We get 223p.

Thus 19p-17(-12p-15) simplifies to 223p + 255.

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;
