Answer:
Step-by-step explanation:
The distribution is skewed right because most data concentrated to the left (preschool age or younger) and have longer tail to the right.
Given that the triangle CDE is similar to triangle CML, it means that the ratio of their corresponding sides are equal. It means that
CD/CM = DE/ML = CE/CL
CD = 20 + 12x + 2 = 12x + 22
CE = 30 + 12 = 42
20/12x + 22 = 12/42
By cross multipying, it becomes
12(12x + 22) = 20 * 42
144x + 264 = 840
144x = 840 - 264 = 576
x = 576/144
x = 4
Both A and B will be answers to the solution.
Since you already have the equation set and equal to 0, you can find the roots by first getting your a, b, and c values for the quadratic equation.
a = 1 (number attached to the x^2)
b = -3 (number attached to the x)
c = 5 (number not attached to a variable)
Then we can use these values in the quadratic equation.

Assuming you meant...
'Johan is selling baseball cards for 12$ each. He is selling 8 cards and says he'll make 8$ profit. How is it reasonable if the answer is correct?'
The answer is reasonable if he is only making a $1 profit per baseball card. For example if he bought the baseball cards for $11 and is selling them for $12, than he only makes $1 for every cards sold. If he sells 8cards, he'll make an $8 profit.
