Write the equation of the graph shown below in factored form. the graph starts at the bottom left and continues up through the x
netineya [11]

For each x intercept the corresponding factor can be deduced. For x intercepts given at 1,2,3 , the equation can be written as

y= (x-1) (x-2) (x-3)

Because x=1 therefore x-1=0 , similarly x=2 , x-2=0 and , x=3 , x-3=0

or

y= x²+2x-3 (x-3)

or

y= x³+2x²-3x-3x²-6x+9

y= x³-x²-9x+9

Ramen noodles. There are 20 ramen noodle packages in a bag. There are 10 beef flavored, and the other 10 are chicken flavored. W
Elina [12.6K]

Answer:

0.789

Step-by-step explanation:

Number of beef flavored Ramen noodles = 10

Number of chicken flavored Ramen noodles = 10

Total number of noodles = 20

Number of ways to select 3 packages:

_{20}C_3= \dfrac{20\times 19\times 18}{3\times 2\times 1}=1140

Number of ways to select two beef flavored Ramen noodle = _{10}C_2 = 45

Number of ways to select one chicken flavored Ramen noodle = 10

Number of ways to select two chicken flavored Ramen noodle = _{10}C_2 = 45

Number of ways to select one chicken flavored Ramen noodle = 10

Total number of ways so that one chicken and one beef Ramen selected = 450 + 450 = 900

Formula for probability of an event E can be observed as:

P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}

Required probability is:

\dfrac{900}{1140} = 0.789

\bf a^{\frac{{ n}}{{ m}}} \implies  \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}

|a|\implies 
\begin{cases}

-a
\end{cases}\implies \pm a\\\\
-------------------------------\\\\
(16x^2)^{\frac{1}{2}}\implies \pm\sqrt[2]{(16x^2)^1}\implies \pm\sqrt{4^2x^2}\implies \pm\sqrt{(4x)^2}\implies \pm 4x
