Surface of a square wall is paved with tiles.The total expenditure at the rate Rs 25 per sq.m is RS.1 76 400.What is the length

Assoli18 [71]

It is given in the question that

Surface of a square wall is paved with tiles.The total expenditure at the rate Rs 25 per sq.m is RS.1 76 400.

Let the side be of length s meter .

And area of square is

$Area = s^2$

So according to question ,

$25s^2 = 176400$

Dividing both sides by 25

$s^2 = 7056$

Taking square root to both sides,

$s = \sqrt{7056}
\\
s =84 meter$

So the required side length is 84 meter .

lutik1710 [3]

Answer:

The correct statement is

The null hypothesis is $H_o : p = 0.18$

The alternative hypothesis is $H_a : p > 0.18$

Step-by-step explanation:

From the question we are told that

The population proportion is p = 0.18

The sample size is n = 1240 airplane

The number of airplane is k = 310

Generally the sample proportion is

$\^ p = \frac{k}{n}$

=> $\^ p = \frac{310}{1240}$

=> $\^ p =0.25$

The null hypothesis is $H_o : p = 0.18$

The alternative hypothesis is $H_a : p > 0.18$
