Answer:

Stem        Leaf

8         |      7,8

9         |      1,3,5,5

10        |     4,5,7,8,8,9

11         |     2,4,5,7

12        |     1,2

13        |     4

14        |     2

Where 8|7 means 87 for example.

Step-by-step explanation:

For this case we have the following data:

104, 88, 121, 114, 107, 91, 95, 117, 109 ,105, 87, 93 ,134, 142, 122 ,95,115, 112 ,108, 108.

The first step is order this data set on increasing way and we got:

87, 88, 91, 93, 95, 95, 104, 105, 107, 108, 108, 109, 112, 114, 115, 117, 121, 122, 134, 142

And then we can create the stem leaf plot like this:

Stem        Leaf

8         |      7,8

9         |      1,3,5,5

10        |     4,5,7,8,8,9

11         |     2,4,5,7

12        |     1,2

13        |     4

14        |     2

Where 8|7 means 87 for example.

2 1/2 x 3 1/5 fast please
vova2212 [387]

Step-by-step explanation:

<u>Let's turn each mixed fraction into an improper fraction:</u>

2 \frac{1}{2} =\frac{2}{2} +\frac{2}{2} +\frac{1}{2} =\frac{5}{2}

3\frac{1}{5} =\frac{5}{5} +\frac{5}{5} +\frac{5}{5} +\frac{1}{5} =\frac{16}{5}

<u>Multiply:</u>

\frac{5}{2} \times \frac{16}{5} =\frac{80}{10}

<u>Simplify:</u>

\frac{80 \div 10}{10 \div 10} =\frac{8}{1} =8

8 is your simplified product.

I need help fast please <br><br>Solve this and show steps <br><br>4.5×8-(0.4+9.6-(3.6-1.8))<br>​
valentina_108 [34]

Answer:

27.8

Step-by-step explanation:

You need to do brackets first

3.6-1.8 = 1.8

Then substitute

4.5 x 8- (0.4 + 9.6- 1.8)

0.4+9.6-1.8=8.2

4.5 x 8 - 8.2 =27.8
