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

If f(x)=x^2 is vertically stretched by a factor of 9 to g(x). What is the equation of g(x)?
AlexFokin [52]

Given:

The function is:

f(x)=x^2

This function is stretched by a factor of 9 to g(x).

To find:

The equation of function function g(x).

Solution:

The vertical stretch is defined as:

g(x)=kf(x)           ...(i)

If 0, then the function f(x) compressed vertically by factor k.

If k>1, then the function f(x) stretched vertically by factor k.

The given function f(x) is stretched by a factor of 9 to g(x).  So the value of k is 9.

Substituting k=9 in (i), we get

g(x)=9f(x)

g(x)=9x^2            [\because f(x)=x^2]

Therefore, the required function is g(x)=9x^2.

PLEASE HELP !!!!!!! does any one know how to write 95.417 in expanded form with multiplication
mixer [17]

Answer:


Step-by-step explanation:

The 9 in 95 tells us how many tens are in the number 95.417; the 5 tells us how many ones, and the 4 how many tenths.  And so on.

Thus,

95.417 = 9*10^1 + 5*10^0 + 4*10^(-1) + 1*10^(-2) + 7*10^(-3)

is 95.417 in expanded form, with each digit multiplying a power of 10.

2/5x+1/4x=26 what is x
shepuryov [24]

Answer:

x = 40

Step-by-step explanation:

2/5x + 1/4x = 26

~Find common denominators

8/20x + 5/20x = 26

~Combine like terms

13/20x = 26

~Multiply 20/13 to both sides

x = 40

Best of Luck!
