Answer:
There are no real solutions
Step-by-step explanation:
Recall that for a quadratic equation in the form:
ax² + bx + c = 0
using the quadratic formula, that the discriminant of the formula is given by the following expression
Discriminant = b² - 4ac
If b² - 4ac < 0 ----> No real roots
If b² - 4ac > 0 ----> Two real roots
If b² - 4ac = 0 ----> One real roots
In our case, a = 3, b = -2 and c = 4
b² - 4ac = (-2)² - 4(3)(3) = 4 - 36 = -32 (which is <0)
Hence there are no real roots.
Answer:
100 fiddler crabs
Step-by-step explanation:
If the 30 crabs are a representation of the entire population, then 6 marked crabs in a population of 30 would mean that
6 / 30 = 0.20 or 20%
20% of the entire crab population are marked. Since we know that a total of 20 fiddler crabs are marked in the pond then we can divide this number of marked crabs by 20% in decimal form to get the estimated total size of the fiddler crab population
20 / 0.20 = 100 fiddler crabs
