Answer:

The actual wide of the lawn is 24 meters

Step-by-step explanation:

we know that

The scale drawing is

$\frac{2}{1}\frac{mm}{m}$

using proportion

Find out how wide is the actual lawn if the lawn is 48 millimeters in the drawing

Let

x -----> the actual wide of the lawn

$\frac{2}{1}\frac{mm}{m}=\frac{48}{x}\frac{mm}{m}\\\\x=48/2\\\\x=24\ m$

therefore

The actual wide of the lawn is 24 meters

Answer:

95% Confidence interval for the variance:

$3.6511\leq \sigma^2\leq 34.5972$

95% Confidence interval for the standard deviation:

$1.9108\leq \sigma \leq 5.8819$

Step-by-step explanation:

We have to calculate a 95% confidence interval for the standard deviation σ and the variance σ².

The sample, of size n=8, has a standard deviation of s=2.89 miles.

Then, the variance of the sample is

$s^2=2.89^2=8.3521$

The confidence interval for the variance is:

$\dfrac{ (n - 1) s^2}{ \chi_{\alpha/2}^2} \leq \sigma^2 \leq \dfrac{ (n - 1) s^2}{\chi_{1-\alpha/2}^2}$

The critical values for the Chi-square distribution for a 95% confidence (α=0.05) interval are:

$\chi_{0.025}=1.6899\\\\\chi_{0.975}=16.0128$

Then, the confidence interval can be calculated as:

$\dfrac{ (8 - 1) 8.3521}{ 16.0128} \leq \sigma^2 \leq \dfrac{ (8 - 1) 8.3521}{1.6899}\\\\\\3.6511\leq \sigma^2\leq 34.5972$

If we calculate the square root for each bound we will have the confidence interval for the standard deviation:

$\sqrt{3.6511}\leq \sigma\leq \sqrt{34.5972}\\\\\\1.9108\leq \sigma \leq 5.8819$

What is the completely factored form of t^4 − 16

MatroZZZ [7]

Since both terms are perfect squares, factor using the difference of squares formula, a^ 2 − b ^2 = ( a + b) ( a − b ) where a = t ^2 and b = 4 .

Answer: ( t^ 2 + 4 ) ( t + 2 ) ( t − 2 )
