Find the mean for the set of data.<br> 0.2, 0.21, 0.17, 3.22, 0.2
Sholpan [36]

Answer:

0.8

Step-by-step explanation:

Find the mean of the list:

(0.2, 0.21, 0.17, 3.22, 0.2)

The mean of a list of numbers is given by:

(sum of elements)/(number of elements)

(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)

Counting, we see that the list has 5 elements:

(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5

0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:

4/5

4/5 = 0.8:

Answer:  0.8

4 &lt; 4x- 16<br> Please answer!
anzhelika [568]

Answer:

First you need to get your variable(x) by itself.

You do that by adding 16 to both sides of the greater than sign.

The 16 cancels or goes away. and 16 + 4 =20.

Your new equation is 20<4x

Finally you divide 20 by 4 to get 5

Your answer is 5<x or x>5.

Plz help!I don’t understand
Alla [95]
H is the correct choice.

The diagram means that parallelograms come in two kinds: rectangles and rhombuses.

So,
.. all rhombuses are parallelograms
.. all rectangles are parallelograms
.. no rectangles are rhombuses
This diagram only recognizes parallelograms that are rectangles and rhombuses. There are also other kinds of parallelograms, but those are not shown here.
