Alocal store’s clearance rack is full of dvds selling for $8 each and cds selling for $6 each. let x represent the number of dvds, and let y represent the number of cds. which inequality can be used to find combinations of dvds and cds that can be bought with a $50 gift card?

Step-by-step explanation:

Let

x------> the number of DVDs

y------> the number of CDs

we know that

-------> inequality that represent the situation

The solution is the shaded area below the solid line between the positive values of x and y

The equation of the line is

The slope of the line is negative

The y-intercept of the line is the point

The x-intercept of the line is the point

The solution is the triangular area in the attached figure

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;
