Answer:
x=2
Step-by-step explanation:
(x+2)(x-6)= y
0 = x+2 0 = x-6
The zeros of the functions are at -2 and 6 using the zero product property
We know a parabola is symmetric so the vertex is 1/2 way between the zeros
(-2+6)/2 = 4/2 =2
The x coordinate of the vertex is at 2
Sorry i dont know the answer

Answer:
This distribution should be expected to be right skewed.
Step-by-step explanation:
Pearson skewness:
The skewness of a data set is given by the subtraction of the mean by the mode, divided by the standard deviation.
If the coefficient is positive, the distribution is right skewed.
If the coefficient is negative, the distribution is left skewed.
If the coefficient is sufficiently close to 0(+/- 0.05), the distribution is bell shaped.
In this question:
Mean 7.4, mode 4, standard deviation 11
(7.4-4)/11 = 3.4/11 = 0.31
Positive coefficient, so right skewed.
