Answer:
325 miles
Step-by-step explanation:
Given that,
A car travels 390 miles in 6 hours.
We need to find the distance travelled in 5 hours.
6 hours = 390 miles
1 hour = 65 miles
In 5 hours,
5 hours = (65×5) miles
= 325 miles
So, it will travel 325 miles in 5 hours.

Answer:

Step-by-step explanation:
The marginal cost function, C'(x), is the derivate of the cost function, C(x).
Therefore, we can obtain the cost function by finding the integral of the marginal cost function:

Where 'a' is a constant and represents fixed costs. If fixed costs are $3,000, the cost function is:

There are 25 species of trees, each with a known abundances. The question is how many possible ways to randomly select one tree there are.
We should calculate the number of combinations. Combinations, because we select item/s from a collection. In this case, when we select only one item, the combination is also a permutation. From set of n objects we select r. In our case: n=25, r=1.
The equation is: n!/r!(n-r)!= 25!/1!*24!=25*24!/24!=25
There are 25 different outcomes (events).
