I think its 5 because 5 times 20 is 100
The answer would be 198/300. That simplified would be 33/50. If you want a percent, it would be 66%.
Answer:
1400 miles
Step-by-step explanation:
Speed is the time rate of change of distance. It is the ratio of distance to time and is given by the equation:
plane averaged 400 mph on a trip going east, but only 280 mph on the return trip.
The time spent (t₁) in going east is given by:
The time spent (t₂) in going east is given by:
The total time (t) = t₁ + t₂
t = t₁ + t₂ = 8.5 hours
Therefore the one way distance is 1400 miles
Answer:
4
Step-by-step explanation:
Add each sample separately
A.17 B. 47 C. 39 D. 52 E. 45
Then you add them all together which totals 200 sick days
We know that they surveyed 5 schools and 10 students at random from each one. So we want to know the mean of sick days the students took not the schools in all.
So we divide 200/50
And get a mean of 4.
So each student took an average of 4 sick days each in the country.
