Given f(x)= 3x-1 and g(x)= 2x-3, for what value of x does g(x) =f (2)?
Tasya [4]

Answer:

At x = 4 ⇒ g(x) = f(2)

Step-by-step explanation:

* In the functions f(x) = 3x - 1 and g(x) = 2x - 3, the domain is

  the values of  x and the range is the values of y

∵ g(x) = f(2)

* Then you will use the range of f(x) at x = 2 to find the domain of g(x)

∵ The domain of f(x) = 2

∵ f(x) = 3x - 1

∴ f(2) = 3(2) - 1 = 6 - 1 = 5

* The range of f(x) = 5

∵ f(2) = g(x)

∴ 5 = g(x)

∵ g(x) = 2x - 3

∴ 2x - 3 = 5 ⇒ add 3 to both sides

∴ 2x = 8 ⇒ divide both sides by 2

∴ x = 4

* At x = 4 ⇒ g(x) = f(2)

The number and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is shown below. This means, for instanc
dexar [7]

Answer:

Shown below.

Step-by-step explanation:

The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:

   Number:     0     1      2     3      4    5     6     7    8     11     12      

Frequency:    5    16    20   14      3    5     4     4    2      1       1

The probability of an events, say <em>E</em> is the ratio of the number of favorable outcomes to the total number of outcomes.

P(E)=\frac{n(E)}{N}

Compute the probabilities of 0 - 12 hurricanes each season as follows:

Number Frequency Probability

     0       5             0.07

     1              16                   0.21  

     2     20             0.27

     3      14             0.19

     4       3             0.04

     5       5             0.07

     6       4             0.05

     7       4             0.05

     8       2             0.03

    11       1                     0.01

    12         1              0.01

 Total     75             1.00
