Area is proportional to the square of the dimensions. Divide the dimensions by 3, and you divide the area by 3-squared = 9.

I rlly need some help please if ur big brains im going to be asking multiple questions right now

You can break the shape up into a rectangle and a right triangle.

Use your trig ratios to find the missing sides.

Add all the sides up and you have your perimeter!

//

$p = 2(l) + 2(w)$

$p = 2(10) + 2(4)$

$p = 28$

//

$tan = \frac{opp}{adj}$

$\tan(45) = \frac{10}{adj}$

$adj = \frac{10}{ \tan(45) }$

$adj = 10$

${a}^{2} + {b}^{2} = {c}^{2}$

${10}^{2} + 10 {}^{2} = {200}^{2}$

$\sqrt{200} = 14.14213562$

//

$p = 10 + 4 + (4 + 10) + 14.14213562$

<em>*notice how one of the 10 is left out because it is inside the shape so we can't use that to find perimeter.</em>

$p = 42.14$

After extensive measurements of the time necessary to complete the first homework assignment, a teacher determines that there is

MaRussiya [10]

Answer: -1.55

Step-by-step explanation:

Given : Mean : $\mu=100$

Standard deviation : $\sigma=20$

Sample size : $n=60$

Sample mean : $\overline{x}=96$

The test statistic for the population mean is given by :-

$z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

$\Rightarrow\ z=\dfrac{96-100}{\dfrac{20}{\sqrt{60}}}=-1.54919333848\approx-1.55$

Hence, the value of z statistic = -1.55
