One of the events in the Winter Olympics is the Men's 500-meter Speed Skating. The times for this event are shown below.

Find the mean, mode, and median time

Mean:

Step-by-step explanation:

Given

See attachment for data

Solving (a): The mean

Mean is calculated as:

From the attached:

So, the mean is:

Solving (b): The median

; this is an even number. So, the median is:

This implies that the median is the average of the 7th and 8th item.

Next, is to order the data (in ascending order): 36.45, 38.03, 38.19, 39.17, 39.44, 40.1, 40.2, 40.2, 40.3, 43.1, 43.2, 43.4, 43.4, 43.4.

The 7th and 8th items are: 40.2 and 40.2

The median is:

Solving (c): The mode

43.4 has the highest number of occurrence.

So:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
