the length of the rectangle is twice its width. write and solve a system of linear equations to find the length L and width W of

xz_007 [3.2K]

Answer:

2 ( m + 2 m) = 36 is the required linear equation

Length of the rectangle is 12 ft and width = 6 ft

Step-by-step explanation:

Let the width of the rectangle = m ft.

So, the length of the rectangle = 2m ft.

Perimeter of rectangle = 36 ft

Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)

⇒2 ( m + 2m) = 36

or, 2 x 3m = 36

⇒ 6m = 36 , or m = 36/6

⇒ m =6 ft

So, the Width of the rectangle; = m = 6 ft

and the Length of the rectangle = 2 m = 2 x 6 = 12 ft.

The measured weights of 1,000 men in a certain village follow a normal distribution with a mean of 150 pounds and a standard dev

earnstyle [38]

Z = (X-Mean)/SD
z1 = (165 - 150)/15 = +1 
z2 = (135 - 150)/15 = - 1 
According to the Empirical Rule 68-95-99.7 
Mean +/- 1SD covers 68% of the values 
100% - 68% = 32% 
The remaining 32% is equally distributed below z = - 1 and z = +1 
32%/2 = 16%

Therefore,

a) Number of men weighing more than 165 pounds = 16% of 1000 = 160 
b) Number of men weighing less than 135 pounds = 16% of 1000 = 160

What is normal, when it comes to people's body temperature? a random sample of 130 human body temperatures, provided by allen sh

nikitadnepr [17]

The two-sided alternative hypothesis is appropriate in this case, the reason being we are asked "does the data indicate that the average body temperature for healthy humans is different from 98.6◦........?".
The test statistic is:
$Z= \frac{\bar{X}-\mu}{ \frac{s}{ \sqrt{n} } }} =-5.47$
Using an inverse normal table, and halving $\alpha$ for a two-tailed test, we look up $p=0.5-\alpha/2=0.5-0.005=0.495$ and find the critical value to be Z = 2.5758.
Comparing the test statistic Z = -5.47 with the rejection region Z < -2.5758 and Z > 2.5758. we find the test statistic lies in the rejection region. Therefore the evidence does not indicate that the average body temperature for healthy humans is different from 98.6◦.
