A local store is selling fresh tuna. the table below shows the price for the amount of tuna

Mathematics
1 answer:
Tems11 [23]2 years ago
4 0

Answer:

The price for each pound of tuna appears to be the same and the predicted amount of tuna that sells for $50 is 10 pounds

Step-by-step explanation:

I say this because for every 2 pounds it equals 10$ so if u count in two's it will be 6 pounds=$30 and then 8 pounds=$40, but now looks this time it only goes up by one and if u divide the pattern, 1 pound=$5 so $40+$5=$45.But if it was still counting by two's 10 pounds=$50

Shiny White dental insurance costs $258 per year. Approximately one-third of insured people need a filling, which averages $110
sveta [45]

Answer:

  about $145.33

Step-by-step explanation:

Consider a group of 15 customers. They will pay ...

  15 × $258 = $3870

in premiums each year.

One-third of those, 5 customers, will submit claims for fillings, so will cost the insurance company ...

  5 × $110 = $550

And 80% of them, 12 customers, will submit claims for preventive check-ups, so will cost the company ...

  12 × $95 = $1140

The net income from these 15 customers will be ...

  $3870 -550 -1140 = $2180

Then the average income per customer is this value divided by the 15 customers in the group:

  $2180/15 = $145.33

_____

<em>Alternate solution</em>

Above, we chose a number of customers that made 1/3 of them and 4/5 of them be whole numbers. You can also work with one premium and the probability of a claim:

  258 - (1/3)·110 - 0.80·95 = 145.33
