The answer is c=50.272, for other problems like this use the formula: The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle).
2 divided by 47 so d....
Because they say fraction of this listed species are endangered plants
So you use total amount of endangered plant,2....and divide it by the total amount in the whole list 47
34.06 is the the correct way of saying it.
Use substitution
x -4x - 7 = 2
-3x = 9, x = -3
Y = -4(-3) - 7
Y = 12 - 7, y = 5
Solution: x = -3, y = 5
Probability=number of specific outcomes / total number of possible outcomes...
Since they want to know the probability of getting all of the colors the probability is just one.
The sum of all probabilities is always equal to one. In this case:
1/4+1/4+1/4+1/4=1
