The Mean of 10 numbers is 14. Three of the numbers have a mean of 4. The remaining numbers are 15, 18, 21, 5, m, 34 and 14. Find I) the sum of remaining seven numbers, ii) value of m

i will pick c put check it over to be sure

step-by-step explanation:

x + 4/7

step-by-step explanation:

use cymath

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

c. side angle side. u shares the same sides
