Rihanna must put a five dollar deposit down to buy a necklace. If P where presents the full price of the necklace which expression tells how Brianna owes before tax after she has paid the deposit

The expression is P - 5

Step-by-step explanation:

Rihanna already made a deposit of $5 to buy the necklace (given)

Full price of necklace = P

Let m = how much Rihanna has left to pay

Full price of necklace = amount paid + amount left to pay

= 5 + m

So we equate the two full necklace prices

5 + m = P

m = P - 5

Therefore, the amount Rihanna owes before tax = P - 5

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;
