Answer: A. 6

Step-by-step explanation:

From the given histogram we got the following table of frequency distribution:-

X         f

1           5

2          4

3          4

4          1

5           1

7           5

8           4

9           4

10          5

Now, \sum f=5+4+4+1+1+4+4+5=28

\sum Xf=2\cdot5+3\cdot4+4\cdot4+5\cdot1+7\cdot1+8\cdot4+9\cdot4+10\cdot5=168

Now, \text{Mean=}\dfrac{\sum xf}{\sum f}=\dfrac{168}{28}=6

Hence, the mean of this distribution = 6

Area of the full circle would be PI x r^2 = PI x 6^2 = 36 *3.14 = 113.04

the angle is 165

 so area = 165/360 x 113.04

area = 51.8 in^2

 answer is B

Point F' corresponds to point D. point E'. point F. point E.
Zepler [3.9K]

Answer:

  F' corresponds to point F

Step-by-step explanation:

When a point is the result of some transformation, we often designate that result using the base name of the original, with a prime (') added. In this case, we expect that F' is the transformation of point F.

__

<em>Comment on point naming</em>

Of course, points can be given any name you like. These conventions are adopted to aid in communication about transformations and correspondence between points. It would be unusual--even confusing, but not unreasonable, for point F' to correspond to point D, for example. In the case of certain transformations, point F' may actually <em>be</em> point D.

A square pyramid is shown below:
madreJ [45]
Let Surface Area A, a the base edge and h the height:

A = a²+2a√(a²/4+h²)

h=?

pythagorean theorem:

h²=c²-a²

h=√(c²-a²)

h=√(8²-(.7/2)²)= 8

plug it in the above equation A= 11.7ft²

So A is correct
