Answer:
Options 2 and 6
Step-by-step explanation:
Those are the locations of the points on the graph. If you look closely, you will see that it counts by twos.
Answer:
x = 5m/s
Step-by-step explanation:
Distance flying out = 12 km (headwind)
Distance flying back = 12 km (tailwind)
total distance = 12 + 12 =24 km
wind speed = 1km/h
speed going out (with headwind) = (x - 1) km/h
speed coming back (with tailwind) = (x + 1) km/h
Time taken to go out = distance going out / speed going out
= 12 / (x-1)
Time taken to come back = distance coming back / speed coming back
= 12 / (x+1)
total time = time taken to go out + time taken to come back
5 =[ 12/(x-1) ] + [ 12/(x-1)]
expanding this, we will get
5x² - 24x - 5 = 0
solving quadratic equation, we will get
x = -1/5 (impossible because speed cannot be negative)
or
x = 5 (answer)
Step-by-step explanation:
Just post a pic of the page
each part of the box and whisker is 25% (meaning each quartile) There are 4 quartiles so this makes 100%
So, the first being 25% and this is where the below 15 falls.
So, 25%
