Can someone please HELP me on how to do this
frutty [35]

Answer:

4)x= g-c

5)x =u+k

6)x = g-c

7)a=\frac{k}{u}

8)x= \frac{g}{c}

9)a=\frac{4}{12m}

10)x= \frac{2c+3}{3}

11)a=\frac{n+p}{m}

12)a= \frac{ub}{k}

13)a= d -r + c

14)x=\frac{np}{m}

Step-by-step explanation:

4) g= c+x

x= g-c

5) u=x-k

x =u+k

6)g = c+x

x = g-c

7) u=\frac{k}{a} \\\\a=\frac{k}{u}

8) g=xc

x= \frac{g}{c}

9) 12am = 4

a=\frac{4}{12m}

10)-3x+2c = -3

2c = -3 +3x

2c +3 = 3x

x= \frac{2c+3}{3}

11) am= n+p

a=\frac{n+p}{m}

12)u = \frac{ak}{b} \\\\u*b = ak\\\\a= \frac{ub}{k}

13)a-c = d-r

a= d -r + c

14)xm= np

x=\frac{np}{m}

Thickness measurements of ancient prehistoric Native American pot shards discovered in a Hopi village are approximately normally
mariarad [96]

Answer:

a) 0.1587 (or 15.87%)

b) 0.0478 (or 4.78%)

c) 0.7935 (or 79.35%)

Step-by-step explanation:

Find the following probabilities:

(a) the thickness is less than 3.0 mm

We need to find the area under the Normal curve with a mean of 4.5 mm and a standard deviation of 1.5 mm to the left of 3 mm

<h3>(See picture 1 attached) </h3>

We can do that with the help of a calculator or a spreadsheet.

<em>In Excel use </em>

<em>NORMDIST(3,4.5,1.5,1) </em>

<em>In OpenOffice Calc use  </em>

<em>NORMDIST(3;4.5;1.5;1) </em>

and we get the value 0.1587 (or 15.87%)

(b) the thickness is more than 7.0 mm

Now we need the area to the right of 7 (1 - the area to the left of 7)

<h3>(See picture 2 attached) </h3>

<em>In Excel use </em>

<em>1-NORMDIST(7,4.5,1.5,1)  </em>

<em>In OpenOffice Calc use  </em>

<em>1-NORMDIST(7;4.5;1.5;1) </em>

and we get the value 0.0478 (or 4.78%)

(c) the thickness is between 3.0 mm and 7.0 mm

We are looking for the area between 3 and 7

<h3>(See Picture 3) </h3>

Since the area under the Normal equals 1, we have

Area to the left of 3 + Area between 3 and 7 + Area to the right of 7 = 1

Hence,  

0.1587 +  Area between 3 and 7 + 0.0478 = 1

and

Area between 3 and 7 = 1 - 0.1587 - 0.0478 = 0.7935 (or 79.35%)
