As the weight of purchased items increases, the shipping charges increase, as shown in the table below. weight, in oz total shipping cost not more than 5 $9.50 more than 5, not more than 10 $13.25 more than 10, not more than 15 $17.00 more than 15, not more than 20 $20.75 assuming only positive domain values, which statement is true of the graph that represents the total cost, y, in dollars for shipping items that weigh x ounces? the graph is discontinuous at x = 5, x = 10, and x = 15. the range values for the set of the data are 10, 14, 17, and 21. for every 1-ounce increase in weight, the total shipping cost increases by $3.75. the left side of each horizontal interval is a closed circle, and the right side is an open circle.

The graph is discontinuous at x = 5, x = 10, and x = 15.  

Step-by-step explanation:

At weights 5, 10 and 15 oz the graph is discontinuous because the shipping cost increase $3.75 from interval to interval, that is, the shipping has a cost at the interval (0, 5], another cost at the interval (5, 10], another cost at the interval (10, 15] and another cost at the interval (15, 20].

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
