Answer:
Letter B is the correct answer. Median is 4 and IQR is 5.
Step-by-step explanation:
Jason : 8,8,11,13,14,14,15,18,21,22,22,27,27,28,30
median = 18
IQR = 27 - 13 = 14
Ed : 7,12,12,15,19,21,21,21,21,22,23,23,26,27,27
median = 21
IQR = 23 - 15 = 8
Their medians cannot be compared based on their IQR's are 6 points apart
We have been given graph of a downward opening parabola with vertex at point . We are asked to write equation of the parabola in standard form.
We know that equation of parabola in standard form is .
We will write our equation in vertex form and then convert it into standard form.
Vertex for of parabola is , where point (h,k) represents vertex of parabola and a represents leading coefficient.
Since our parabola is downward opening so leading coefficient will be negative.
Upon substituting coordinates of vertex and point (0,0) in vertex form, we will get:
Divide both sides by
So our equation in vertex form would be .
Let us convert it in standard from.
Therefore, the equation of function is standard form would be .
15+15+15+2+2+2+2=(3×15)+(4×2)=45+8=53
