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

<span>Therefore,

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

you need 1 1/4 feet of string to make 20 holiday ornaments. to make 14 holiday ornaments you will need

alexira [117]

we know that

$1\frac{1}{4} =(1*4+1)/4=5/4=1.25 ft$

by proportion

$\frac{1.25}{20} =\frac{x}{14} \\ \\20*x=14*1.25\\ \\x=0.875\ feet$

$0.875\ feet=\frac{7}{8}\ feet$

therefore

the answer is

$\frac{7}{8}\ feet$

Use the tools to graph the solution to the equation 6z−27=27 on the number line below.

krok68 [10]

Answer:

z = 9

Step-by-step explanation:

To find the solution, undo what is done to z. You can start by adding 27 to both sides of the equation.

6z -27 +27 = 27 +27

6z = 54 . . . . . simplify

Now, you can divide by 6 to make the coefficient of z be 1.

6z/6 = 54/6

z = 9 . . . . . . . simplify

Lin created a scaled copy of Triangle A with an area of 72 square units. How many times larger is the area of the scaled copy co

Tju [1.3M]

Answer:

Copy's area is 16 times bigger then triangle area.

Step-by-step explanation:

Given:

Area of copy = 72 unit²

Find:

How bigger copy compared to triangle

Computation:

Area of triangle = [1/2][base][height]

Area of triangle = [1/2][3][3]

Area of triangle = 4.5 unit²

So.

Area of copy / Area of triangle

72 / 4.5

16

So,

Copy's area is 16 times bigger then triangle area.
