Sarah purchased a swing set for $1,450 using a six-month deferred payment plan. The interest rate after the introductory period is 19.99%. No down payment is required, but there is a minimum monthly payment of $20. What is the balance at the beginning of the seventh month if only the minimum payment is made each month during the introductory period? (4 points) a
$1,481.10
b
$1,330.00
c
$1,450.00
d
$1,601.10

answer: h

step-by-step explanation:

c

step-by-step explanation:

i think because what else can be a sample of every member

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;
