Answer:

9,720 meters, or 9.72 km

Step-by-step explanation:

Rob runs at a speed of V1 = 3.8 m/s for t1 = one half hour = 30 x 60 = 1,800 seconds.

=> the distance he runs S1 = V1 x t1 = 3.8 x 1,800 = 6,840 meters

He walks at V2 = 1.6 m/s for t2 = 1,800 seconds.

=> the distance he walks S2 = V2 x t2 = 1.6 x 1,800 = 2,880 meters

The total distance he runs and walks S = S 1 + S 2 = 6,840 + 2,880 = 9,720 meters

(a) Contrast the shapes of the data sets displayed in the box-and-whisker plots in Question 1. Explain
Ganezh [65]

Answer:

Kindly check explanation

Step-by-step explanation:

A.)

Differentiating based on the shape of the box and whisker plot.

The first plot, named shrella depicts a skewed distribution, (negative skew) highlighted by the long whisker (tail) to the left with the median also shifting towatds to the right of the box away from the box center. This could mean that the time difference between the coins aren't even and older coins seem to exhibit a larger time gap than newer coins.

The second plot however. VENITA, depicts a distribution which could be described as normal, as the whiskers are aodt of equal length and the median centered in the middle of the box. This could mean that Venita's coins are evenly spread out based time.

B.)

As for the overall spread, Shrella's plot covers a wider range, hence (larger spread) than Venita's plot. Thanks to the long whiskers in Shrella's plot.

For the spread within the boxes, Venita's plot has a larger within box spread than Shrella. With Venita's plot has a wider box tham Shrella's box plot.

C)

The appropriate measure of centre to be used is the median which is denoted by the vertical line in between the box. Shrella's plot has a median value of about 68 while Venita's has a median value of 60. The median value are still s bit close or similar.
