Answer:

The probability that Jordan does not selects a salamander is \frac{11}{20} or 0.55

Step-by-step explanation:

First, we will have to add up all of the number of animals.

55 + 33 + 12 = 100

Now, we find the ratio of 55 and 100 to get the probability.

55 / 100 = 11 / 20

So, the probability that Jordan does not selects a salamander is \frac{11}{20} or 0.55

Lets factor first to see if we can make the problem simple
2(4x^2-25)
now we see that in parenthesis we have 2 square numbers
4x^2=(2x)^2
25=(5)^2
our expression is now 
2(2x+5)(2x-5)

Keshawn is asked to compare and contrast the domain and range for the two functions.
Lapatulllka [165]

Answer: The correct option is 'The domain of both functions is all real numbers'.

Step-by-step explanation:

Here, functions are f(x) = 5x and g(x) =5x

Since the domain of f(x) is, D= { x : x belongs to all real numbers.}

Therefore, Domain of f(x) is all real numbers.

Since f(x) and g(x) have the same value,

Therefore, Domain of g(x) is also the set of real numbers.

Now, range of f(x) is , R=  { 5x : x belongs to all real numbers.}

Therefore, Range of f(x) is all real numbers.

⇒ Range of g(x) is also all real numbers.

So, we can say by the above explanation, only option (1) is correct.
