The answer would be 5 2/5
Answer: 0
Step-by-step explanation:
We know that if the number of real solutions the quadratic equation depends on the discriminant:-
- If d = 0, then equation will have exactly one real number solution .
- If d > 0 then equation will have exactly two real number solutions.
- If d < 0 then the quadratic equation will have no real solutions. There will be two complex number solutions.
Therefore, if a quadratic equation has exactly one real number solution.
Then, the value of its discriminant= 0.
Answer:
x<3
Step-by-step explanation:
Let us move all the x values to one side and the numerical values to the other:
1>2x+2x-11
1+11>2x+2x
12>4x
3>x or x<3

Answer:
a) 120
b) 10
c) 1/12
Step-by-step explanation:
The number of ways that a sample of r can be selected from a population of n is:
nCr = n! / (r! (n−r)!)
a) 3 people selected from a group of 10
₁₀C₃ = 120
b) 3 women selected from a group of 5
₅C₃ = 10
c) Of the 120 committees that can be chose, 10 are all women. So the probability is 10/120 = 1/12.
