The probability that at least 2 of the dinners selected are pasta dinners will be 0.8181...
<u><em>Explanation</em></u>
Pasta dinners = 7 , Chicken dinners = 6 and Seafood dinners = 2
The student selects 5 of the total 15 dinners. So, total possible ways for selecting 5 dinners
For selecting at least 2 of them as pasta dinners, the student can select 2, 3, 4 and 5 pasta dinners from total 7 pasta dinners.
So, the possible ways for selecting 2 pasta dinners
The possible ways for selecting 3 pasta dinners
The possible ways for selecting 4 pasta dinners
The possible ways for selecting 5 pasta dinners
Thus, the probability for selecting at least 2 pasta dinners
The condition that must not be met before usage us that the coefficient of the x²-term must be positive.
<h3>Equations of quadratic function</h3>
The standard quadratic function is given as;
ax²+bx + c = 0
From the equation shown above, the leading degree of the equation is 2. The following are condition that must be met before you can use
the quadratic formula to find the solutions of an equation.
- There can be no term whose degree is higher than 2.
- The coefficient of the x²-term can't be zero.
The condition that must not be met before usage us that the coefficient of the x²-term must be positive.

Answer: the slope of L is 1 and the slope of k is 2
Step-by-step explanation:
with rise over run, L's rise is 1 and run is 1 so it would be 1/1 which is equal to 1. For k the rise would be 2 and run would be 1 so 2/1. I dont know if you learned it that way but there you go man.
