A triangle is inside a circle where the triangle's base is on the circle's diameter as shown.What is the area of the shaded region?

Answer:

$A_(shaded)= 136.96 ft^(2)$

Step-by-step explanation:

We will find the shaded area if we subtract the area of the triangle from the area of the circle.

We know that the area of the circle is defined as

$A= \pi r^(2)$

Where $r$ is half the diameter, that is

$r=(16ft)/(2)=8ft$

The area of the circle is

$A= \pi r^(2)\nA= 3.14 (8ft)^(2) =200.96ft^(2)$

Now, we have to find the area of the triangle, which is defined as

$A_(\triangle) =(bh)/(2)$

Where $b$ is the base of 16 feet, and $h$ is the height of the triangle which is on the radius. So, we have $b=16ft$ and $h=8ft$ .

The area of the triangle is

$A_(\triangle) =(16ft(8ft))/(2)=64ft^(2)$

Now, the shaded is the difference as we said before, that is

$A_(shaded)=A-A_(\triangle)$

Replacing both areas, we have

$A_(shaded)=200.96 ft^(2) - 64ft^(2)= 136.96 ft^(2)$

Therefore, the shaded area is $A_(shaded)= 136.96 ft^(2)$

area of a circle=pi x r^2= 3.14 x 8^2(half of the radius)=3.14 x 64=200.96

area of triangle= 1/2 bh=1/2(16)(8)=1/2(128)=64

200.96-64=136.96 sq.ft

Simplify the expression: (7 +9i)(8 - 10i)

56 + 2i + 90
56 + 2i – 90i^2

Here is the histogram of a data distribution. All class widths are 1. What is the median of the distribution? A. 10
B. 7
C. 8
D. 6

Answers

Median of the data distribution given in the histogram using the cumulative frequency is 8.

The class width = 1

The values of the data are,

4, 1, 1, 1, 1, 3, 4, 4, 6.

Cumulative frequencies = 4, 5, 6, 7, 8, 11, 15, 19, 25

n = 25 and n/2 = 12.5

Median lies on the 12.5th observation.

12.5th observation lies in the class where cumulative frequency is 15.

Median class is 7.5 - 8.5.

l, lower limit of median class = 7.5

n = 25

f = frequency of median class = 4

cf, cumulative frequency of class preceding the median class = 11

h, class size = 1

Median = l + [(n/2 - cf) / f] h

= 7.5 + [(25/2 - 11) / 4] 1

= 7.875 ≈ 8

First of all, we have to know what median is.

Median- the middle number.

So we have to organize the numbers in roofer from least to greatest, so we have to count how many 2,3,4,5,6s there are and so fourth.

I’ll have them listed for you.

2 2 2 2 3 4 5 6 7 7 7 8 8 8 8 9 9 9 9 10 10 10 10 10 10.

Next step is to find the middle number (s). If it has an even amount of numbers, we have to take the two middle numbers and divided by two.
If there are an odd amount of numbers, we just pick the middle number.
[i.e: 2 3 4; the middle number here is 3]
[i.e: 2 3 4 5; the middle number is 3+4=7 divided by 2 which equals 3.5]

Okay so let’s count how many numbers there are.
There are 25 numbers in total, so therefore there are 2 middle number (s).

So let’s divided 25/2 to get the two middle numbers, which is 12.5, therefore numbers 12-13 are middle numbers.

So let’s count what number is 12 and 13. When you count the numbers in order, you can tell that 8 and 8 are numbers of 8.

The final step is to just calculate by adding both numbers and dividing by two because we are trying to find the middle number(average number).

8 + 8 = 16
16/2= 8

The median for this question is 8.
