Multiply -2 at both sides
d-10=-14
d=-14+10=-4
The answer is -4
Median because there is an outlier (1 million and stuff) that is about 10 times as much as everything else
The 99.87th percentile, or the area to the left of the 3 standard deviation mark it 99.87% better than everyone/everything else.
Answer:
Step-by-step explanation:
<u>Given functions f(x) and g(x). f(x) is:</u>
<u>Converted into vertex form, it is:</u>
<u>g(x) has vertex at (-2, -14), it's vertex form is:</u>
Comparing f(x) and g(x) we see both have same x- coordinate of the vertex (x = -2).
Both have positive leading factors, therefore the vertex is their minimum point.
Function f(x) has vertex above the x-axis as y-coordinate of the vertex is positive. Hence no intersection with x-axis.
Function g(x) has negative y-coordinate of the vertex, so it has two intersections with x-axis.
Correct choice is A
The value of c to complete the square is one. In order to find the c value you divide the b value (-2) by 2 (-1) and then square that. -1 squared is 1. This can then be easily factored into (x-1)^2
