Answer:

a)18.8

b)20

Step-by-step explanation:

Basically, you have to add all the numbers from the data set (188) then divide them by 10 and that equals 18.8

The second part you have to add 32 to 188 ( which equals 210) and that by 11 which equals 20

HELP PLEASE!!!!!! I need help Urgent Help
gavmur [86]
This is just a porportion. So if 250 meters is 1 meter than: 250/1

And it wants to know the height. So we have the first number but not the second. So we'll use x: 212/x

Set them equal to each other 250/1=212/x

Cross multiply: 212=250x

Divide to find x: 212/250=x
x=212/250
x=0.848

So the height of the model, to the nearest 10th would be 0.8 meters.

5. Verify the property a× (b-c)= a×b-a×c for each of the following:<br>a= -3\5; b= 5\9; c= -10\3​
ohaa [14]

Answer:

We conclude that

a\times \left(b-c\right)=\:a\times b-a\times c

           -\frac{7}{3}=-\frac{7}{3}

        L.H.S = R.H.S    

Step-by-step explanation:

Given the property expression

a\times \left(b-c\right)=\:a\times b-a\times c

Given that:

  • a = -3/5
  • b = 5/9
  • c = -10/3

<u>Determining the LEFT-HAND SIDE</u>

a\times \left(b-c\right)

substituting a= -3/5, b= 5/9 and c= -10/3​

a\times \left(b-c\right)\:=\:\:-\frac{3}{5}\times \left(\frac{5}{9}-\left(-\frac{10}{3}\right)\right)\:\:\:\:\:\:\:\:\:\:\:\:

                  =-\frac{3}{5}\times \:\left(\frac{5}{9}+\frac{10}{3}\right)\:\:\:

                  =-\frac{3}{5}\times \frac{35}{9}

                   =-\frac{7}{3}

<u>Determining the RIGHT-HAND SIDE</u>              

\:a\times \:b-a\times \:c

substituting a= -3/5, b= 5/9 and c= -10/3​

\:a\times \:b-a\times \:c=ab-ac

                      =-\frac{3}{5}\left(\frac{5}{9}\right)-\left(-\frac{3}{5}\right)\left(-\frac{10}{3}\right)

                      =-\frac{3}{5}\cdot \frac{5}{9}-\frac{3}{5}\cdot \frac{10}{3}

                      =-\frac{15}{45}-\frac{30}{15}

                      =-\frac{1}{3}-2

                      =\frac{-7}{3}

Apply the fraction rule:  \frac{-a}{b}=-\frac{a}{b}

                      =-\frac{7}{3}

Therefore, we conclude that

a\times \left(b-c\right)=\:a\times b-a\times c

           -\frac{7}{3}=-\frac{7}{3}

        L.H.S = R.H.S
