1) Mean= Sum of total Observation/ Total no.of observation
Mean= 42/6=7
option (b) 7

2)To calculate Median first arrange the numbers in a numerically ascending order.

Since, there are even no.of total Observation median will be the mean of two middlemost terms.

3,6,7,9,9,10

Middle terms are 7 and 9
Median= 7+9/2= 8

The right answer is Option A: $x=\frac{rs-t}{2}$

Step-by-step explanation:

Given expression is;

$s=\frac{2x+t}{r}$

We will solve this expression for x, therefore,

Multiplying both sides by r

$r*s=\frac{2x+t}{r}*r\\rs=2x+t$

Subtracting t from both sides

$rs-t=2x+t-t\\rs-t=2x\\2x=rs-t$

Dividing both sides by 2

$\frac{2x}{2}=\frac{rs-t}{2}\\x=\frac{rs-t}{2}$

The right answer is Option A: $x=\frac{rs-t}{2}$

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s an

NeX [460]

Answer:

$6400\ \text{N}$

Step-by-step explanation:

$\dfrac{m}{t}$ = Mass flow rate of water = 320 kg/s

$m$ = Mass of water on the door

$t$ = Time

$v$ = Velocity of water on the door = 20 m/s

Force is given by

$F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}$

The average force is exerted by the stream of water is $6400\ \text{N}$ .
