Answer:
50%
Step-by-step explanation:
Let the total number of trees be T and suppose that this is made up of eucalyptus trees E and other kinds of trees, O.
Then E+O=T, and since 99% of the trees are eucalyptus trees, EE+O=0.99.
Therefore
0.99E+0.99O=E
0.01E=0.99O
E=99O.
Suppose we reduce the number of eucalyptus trees by some amount x and that the remaining number of eucalyptus trees are now 98% of the total trees.
Then we would have E−x(E−x)+O=0.98.
Therefore,
0.02(E−x)=0.98O
0.02E−0.02x=0.98O
0.02x=0.02E−0.98O
x=E−50(0.98)O
x=E−49O
x=E−49(E99)
x=5099E≈0.505050...×E.
So we end up removing a little over half of the eucalyptus trees. EDIT: Forgot to mention - removing 50.505050...% of the eucalyptus trees means that we are removing 0.50505050....×0.99T which is 0.5T or half the trees in the neighborhood.
Maybe you're confused by this number e.
Replace e with the number 2 and rethink your options:
x^2
2^x
2x
So you think maybe it's C.
2x represents a straight line, ya?
Straight line is going to grow much slower than x^2, a parabola, ya?
But both of those will grow much much slower than an exponential function 2^x.
Oh oh I misread the question.. they wanted the SLOWEST growth, not the fastest. Yes you have the correct option! :)

When the sample is given, the number of elk are likely to be infected is to be considered as the 450.
<h3>Calculation of the number of elk:</h3>
Since the population is 7,500.
The random sample is 50.
So here be like
÷ ×
= 450
hence, When the sample is given, the number of elk are likely to be infected is to be considered as the 450.
