Is a standard deviation of 10 a large number indicating great variability, or is it a small number indicating little variability?
To answer this question correctly one should look carefully at the value of the:

a) mean
b) standard deviation
c) mean divided by the standard deviation
d) co-efficient of variation

it would to have a graph or something ! but i had this question so its false

step-by-step explanation:

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

imma say 16%. sorry if its wrong. i'm doing the same stuff right now
