The answer to your question is 1.70
Answer:
40%
Step-by-step explanation:
She has sold 20 items total.
Refrigerators: 8/20 = 40%
Dishwashers: 1/20 = 5%
Dryers: 11/20 = 55%
So there is a 40% chance she will sell another refrigerator! hope this helps!!
For the equation:
-1=5 x^2 - 2 x
5 x^2 - 2 x + 1 = 0, then we substitute: a=5, b=-2, c =1
to discriminant formula: D= b^2 - 4 a c = (-2)^2 - 4 * 5 * 1 = 4 - 20 = - 16
Answer:
The discriminant is equal to -16 which means the equation has no real number solutions.
