244 - 165 = 79 . . . . one standard deviation
323 - 244 = 79 . . . . one standard deviation

The range of scores is ±1 standard deviation from the mean. The empirical rule says 
   68% of scores lie in that range.

Can someone help will mark brainlist
Marina86 [1]

Answer:

See below

Step-by-step explanation:

the common ratio, r <1    so it CONVERGES    (r = 1/2 in this series)

sum = a1 ( 1-r^n) / (1-r) =  1000(1-.5^10)/(1-1/2) = ~1998

    for n= 30    this results in ~~2000

As it continues, the terms get smaller and smaller and the SUM converges on 2000.

WARRIOR [948]

Answer:

Domain → 0 < x < 5

Step-by-step explanation:

Sasha sells T-shirts and earns a fixed amount plus a commission by selling each shirt. (As given in the table)

Table attached shows a linear function (A regular increase in total pay with the increase in number of shirts sold)

So the input values of the table (Number of shirts sold) will represent the domain of the linear function.

Hence, reasonable domain for the function will be → 0 < x < 5
