Q4.

The coding of the statistic is used to make it easier to work with the large sunshine data set

The mean of the sunshine is 3.05 $\overline 6$

The standard deviation is approximately 18.184

Reason:

The given parameters are;

The sample size, n = 3.

∑x = 947

Sample corrected sum of squares, Sₓₓ = 33,065.37

The mean and standard deviation = Required

Solution:

$Mean, \ \overline x = \dfrac{\sum x_i}{n}$

The mean of the daily total sunshine is therefore;

$Mean, \ \overline x = \dfrac{947}{30} \approx 31.5 \overline 6$

$s = \dfrac{x}{10 } - \dfrac{1}{10}$

$E(s) = \dfrac{Ex}{10 } - \dfrac{1}{10}$

$E(s) = \dfrac{31.5 \overline 6}{10 } - \dfrac{1}{10} = 3.05 \overline 6$

The mean ≈ 3.05 $\overline 6$

Alternatively

, $The \ mean \ of \ the \ daily \ total \ sunshine, \, s = \dfrac{31.5 \overline 6 - 1}{10 } = 3.05\overline 6$

The mean of the daily total sunshine, $\overline s$ ≈3.05 $\overline 6$

$Var(s) = Var \left(\dfrac{x}{10 } - \dfrac{1}{10} \right)$

$Var(s) = \left(\dfrac{1}{10}\right)^2 \times Var \left(x \right)$

Therefore;

$Var(s) = \left(\dfrac{1}{10}\right)^2 \times 33,065.37 = 330,6537$

Therefore;

$s = \sqrt{330.6537} \approx 18.184$

The standard deviation, $s_s$ ≈ 18.184

the area of asquare field is 2.25 hectares.find its perimeter in metres if hectare is qual to 10000square metres

Sergio [31]

Answer:

Perimeter of the square field is 600 meters.

Step-by-step explanation:

Given:

Area of a square field = 2.25 hectares

1 hectare = 10000 m²

∴2.25 hectares = $2.25\times10000 = 22500$ m²

Now, let each side length of the square field be $a$ meters.

∴ Area = $a^{2}$

⇒ $22500 = a^{2}$

⇒ $a=\sqrt{22500}=150$ m

Now, perimeter of a square is given as, $P = 4a$ .

Here, $a=150$ m.

∴ $P=4\times150=600$ m

Hence, the perimeter of the square field is 600 meters.
