Arrange the summation expressions in increasing order of their values.
nalin [4]
We'll solve for each one of them:

\sum_{i=1}^{4}4(5)^{i-1} = (4(5)^{1-1}) + (4(5)^{2-1}) + (4(5)^{3-1}) + (4(5)^{4-1})
=4+20+100+500 = 624

\sum_{i=1}^{5}3(4)^{i-1} = (3(4)^{1-1}) + (3(4)^{2-1}) + (3(4)^{3-1}) + (3(4)^{4-1}) + (3(4)^{5-1})
=3+12+48+192+768=1023

\sum_{i=1}^{2}5(6)^{i-1} = (5(6)^{1-1}) + (5(6)^{2-1})
=5+30=35

\sum_{i=1}^{4}5^{i-1} = (5^{1-1})+(5^{2-1})+(5^{3-1})+(5^{4-1})
=1 + 5+ 25+125 = 156

So, our totals are: 624, 1023, 35, and 156. So clearly, 1023 > 624 > 156 > 35. W can write it as (your answer):

\sum_{i=1}^{2}5(6)^{i-1}

Hope this helps! If anything is confusing, you can always DM me.

50 points!! will mark brainliest to correct answer!!
Mamont248 [21]
I think your image for your regression line didn't show up, but judging from what I see, the answer should be:
<span>D) In step 4, Tameka mistakenly based the strength of the association on the slopes.

This is because the strength of the association is not determined by the slope of the regression line, but by how close the data points were to the actual line. The closer the points are to the actual regression line, the stronger the association.
