The answer is 29 flies.
x is the number of weeks. We have 2 weeks, so x = 3
1. Calculate the population of flies after 3 weeks: p(3) = ?
2. Calculate how much flies are eaten by the spider after 3 weeks: s(3) = ?
3. Subtract the number of flies after 3 weeks and eaten flies after three weeks: p(3) - s(3) = ?
1. p(x) = 5 · 2ˣ
p(3) = 5 · 2³ = 5 · 8 = 40
2. s(x) = 3x + 2
s(3) = 3 · 3 + 2 = 9 + 2 = 11
3. p(3) - s(3) = 40 - 11 = 29
The set that is more variable is the daily temperature as they won't be clustered but rather spread out.
<h3>How to know the set that's more variable?</h3>
The mean of the temperature will be:
= (51 + 37 + 53 + 27 + 91 + 50 + 50 + 83 + 83 + 90)/10
= 615/10
= 61.5
The mean of the precipitation will be:
= (4.5 + 3.8 + 1.4 + 2.4 + 2.8 + 4.6 + 4.7 + 2.3 + 1.5)/10
= 28/10
= 2.8

Your answer x=−1.387158,0.295703
Take the three and divide it with the 12 which would get you 4 so put a open circle Above the 4 and make the line go to the left I think I hope this will help
