Answer:
The number is 2.
Step-by-step explanation:
If the number is x then:
x + 2x^2 = 10
2x^2 + x - 10 = 0
2x^2 - 4x + 5x - 10 = 0
2x(x - 2) + 5(x - 2) = 0
(2x + 5)(x - 2) = 0
x = 2.
False, the min and max of A are the same distance as the min and max of B from each other, therefore the standard deviation is the same.
Total food:
8.50 + 1.99 = $10.49
