Because it will be half2 standard deviation which will include 500-700.
2std will include from 300-700.
so it will be half of 95%.
Well you have to change the first number in ALL of the () so
(-1,1) = (1,1)
(-2,-1) = (2,-1)
(-1,0) = (1,0)
so your answer is d <span>(1, 1), B(2, -1), C(1, 0)</span>
60=5k is the answer for your question
<span>Changing the grouping of the addends should not change the sum, according to the associative property of addition. You might group them differently with (50 + 3) + 47, so that you have 50 + (3 + 47). You might not regroup them with (16 + 4) + 5 rather than 16 + (4 + 5).</span>
