The following table shows the data collected from a random sample of 100 middle school students on the number of hours they play indoor games every week: Weekly Duration of Indoor Games

Time (in hours) 0–3 4–7 8–11 12–15
Number of Students 4 42 52 2

There are 1,300 students in the school. Based on the sample proportion, how many students in the school would be expected to play indoor games for at least four hours every week? (pls explain ) :)

b, i believe, but not sure.

i believe that the slope of the line is -5

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
