The combined weight of the pumpkins would be
74 and 15/16 pounds
As you can see, 4 of the 24 students don't partecipate in any activity. This clearly implies a ratio of 4:24, or 1:6.
We could infer that this ratio holds for the whole school, or even for all the boys and girls of that age.
That's the point of surveys and inferring: you gather data about a relatively small group, and then assume that the proportions you have are valid for a much larger group.
That's why it is important that the group that you survey is balanced and unbiased.
240 = 16x is about an equation but you can make it more complicated by adding unneeded parts for example 240 = 16x - 81 + ((15x) + 15) - (x^2 / 2) - 45 - 1.5.
Step-by-step explanation:
Since they are complementry angles :
(12x-9) + (8x + 14) = 90°
20x + 5 = 90°
X = 4.25 °
Angles are 42° and 48°.
