Answer:
Box and Whisker Plot
Step-by-step explanation:
Box and Whisker Plot is a visual display of a data set in statistics used to display a 5-number summary. The five number summary is the minimum value, the maximum value, the median, the upper quartile, and the lower quartile.
For the box plot a box is drawn from the first quartile to the third quartile with a vertical line going through the box at the median. Also, the whiskers go from each quartile to the minimum or maximum.
2x^2 + 9x + 4 = 0
x^2 + 9/2*x + 2 = 0
x = - 9/4 +- √(81/16 - 32/16) = - 9/4 +- 7/4
x1 = - 1/2
x2 = - 4
Step-by-step explanation:
an = a1 + 4×[2^(n -1) - 1]
