Question
P(t) = 250 + 10t
The population of snow leopards in a certain area can be modeled by the function P defined above, where P(t) is the population t years after 1990 . Of the following, which is the best interpretation of the equation P(30) = 550 ?
- The snow leopard population in this area is predicted to be 30 in the year 2020.
- The snow leopard population in this area is predicted to be 30 in the year 2030
- The snow leopard population in this area is predicted to be 550 in the year 2020
- The snow leopard population in this area is predicted to be 550 in the year 2030
The correct answer is: The snow leopard population in this area is predicted to be 550 in the year 2020
HINT :- P(30) = 550 in comparison to p(t) we get t = 30 years after 1990 and the population of snow leopard is p(t) if t = 30 the population predicted will be 550 (= p(30)).
Given ,P(30) = 550 in comparison to p(t) we get t = 30 years after 1990 .
The present year is 1990+30 = 2020 .
Here, P(30) = 550 means the snow leopard population in this area is predicted to be 550 in the year 2020

The scatterplot above shows data for ten charities along with the line of best fit. For the charity with the greatest percent of total expenses spent on programs, which of the following is closest to the difference of the actual percent and the percent predicted by the line of best fit?
Expenses are sums of money spent on goods or services. It is defined as the amount of money required to obtain something."It takes money to make money," as the adage goes. Supplier payments, employee wages, factory leases, and equipment depreciation are all everyday expenses.
For example, running a car can be costly in terms of fuel, repairs, and insurance.
Profit (P): When a product is sold for more than its cost, the seller makes a profit.
Loss (L): When a product is sold for less than its cost, the seller suffers a loss.
