Answer: I’m pretty sure it’s 1/9
Step-by-step explanation:
You multiply 1/3x1/3 because the probability she’s chooses soup is 1/3. And the probability of her choosing juice is 1/3. The reason those are 1/3 because she has 3 things to choose from and she’s choosing one of them. So now you multiply 1/3 x 1/3 witch will get you 1/9. Hope this helps! HAVE A GOOD DAY!

Write the vertex form of the equation and find the necessary coefficient to make it work.
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2
You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1
The equation you seek is
.. y = x^2 +6x +7
.. y = a*(x +3)^2 -2
.. = ax^2 +6ax +9a -2
You require the y-intercept to be 7. So, for x=0, you have
.. 9a -2 = 7
.. 9a = 9
.. a = 1
The equation you seek is
.. y = x^2 +6x +7
