Answer:

first and last

Step-by-step explanation:

Total observations:

3 + 7 + 7 + 4 + 1 = 22

There are 22 observations, so data from 22 households

Median position: (n + 1)/2

(22 + 1)/2 = 23/2 = 11.5th value

median is the average of 11th and 12th values, both are 2. So the average is also 2

Therefore, Centre is at 2

The speed of boat in still water is 15km/hr if needs 4 more his to travel 63 km against the current of a river than it needs to

hram777 [196]

Answer:

$\frac{63}{15 - c} - \frac{63}{15 + c} = 4$

Step-by-step explanation:

The systems of equations are

Let us assume the rate of the current be c

Now actual speed against the current is (15 - c)

And, the actual speed with the current is (15 + c)

Here we applied the time formula i.e. distance by speed

Also the upstream time - downstream time = 4

Now the equations are

$\frac{63}{15 - c} - \frac{63}{15 + c} = 4$

The volume of a sphere is 4/3 * pi * r³ so substitute the values in

4/3 * pi * 2³

4/3 * pi * 8

32/3 * pi

The volume is either 32/3pi units³ or 33.49 units³ (they're the same value)

I hope this helps!
