Answer:

Size 50

Step-by-step explanation:

You should choose the larger sample size.  This is because if you take the mean, it will help to cancel out outliers.  For instance, most people exercise half an hour.  With sample size of 10, there might be one person who doesn't exercise, thus dragging down the mean.  A larger sample size would have a greater ratio of "average" people.

At the beginning of an environmental study, a forest covered an area of 1500 km2 . Since then, this area has decreased by 9.8% e
fredd [130]

Answer:

A(t)=(0.902)^t \cdot 1500 [km^2]

Step-by-step explanation:

In this problem, the initial area of the  forest at time t = 0 is

A_0 = 1500 km^2

After every year, the area of the forest decreases by 9.8%: this means that the area of the forest every year is (100%-9.8%=90.2%) of the area of the previous year.

So for instance, after 1 year, the area is

A_1 = A_0 \cdot \frac{90.2}{100}=0.902 A_0

After 2 years,

A_2=0.902 A_1 = 0.902(0.902A_0)=(0.902)^2 A_0

And so on. So, after t years, the area of the forest will be

A(t)=(0.902)^t A_0

And by substituting the value of A0, we can find an explicit expression:

A(t)=(0.902)^t \cdot 1500 [km^2]
