Consider the function graphed below.
aivan3 [116]

Answer:

B. (see attached)

Step-by-step explanation:

All the answers agree that the function is x² for x < 1. Where they disagree is in the slope and y-intercept of the linear portion for x > 1.

The line has a slope that is less than 1 unit of rise for 1 unit of run, so will not be selections A or C, which have slopes of 3.

The y-intercept is clearly positive if we extend the line to the left until it reaches the y-axis. This eliminates selection D from consideration, leaving only selection B.

These data show the number of miles each of the 9 members of a track team ran for the week. 11 11.5 10.5 17 14.5 14.5 18 17 19 W
Vitek1552 [10]
Given:
<span>11 11.5 10.5 17 14.5 14.5 18 17 19

Arrange in chronological order from least to greatest.
10.5 ; 11 ; 11.5 ; 14.5 ; 14.5 ; 17 ; 17 ; 18 ; 19

</span><span>I used an online lower and upper fence calculator to get the necessary data.

Minimum: 10.5
Maximum: 19
Q1: 11.25
Q2 or median: 14.5
Q3: 17.5

Interquartile range can be solved by subtracting the value of Q1 from the value of Q3

IQR = Q3 - Q1
IQR = 17.5 - 11.25
IQR =  6.25  CHOICE A. </span>
