Find the area of the shaded region.

Find The Area Of The Shaded Region.

Answers

Answer 1

Answer:

Step-by-step explanation:

Remark

The method of finding the area of the ring is to find the area of the outer ring and subtract the area of the hole in the middle.

Outer ring

r = 10 + 4  = 14 inches

Area = pi * r^2

Outer ring area = pi * 14^2

Outer ring area = 196 pi

Inner hole

Area unshaded part = pi * r^2

r = 10

Area = pi * 10^2

Area = 100 pi

Area of the shaded part

area of the shaded part = outter circle area - inner circle area

outter circle area = 196 * pi

inner circle area = 100 pi

Area of the shaded part = 196 pi - 100 pi

Area of the shaded part = 96 pi

pi = 3.14

Area of the shaded part = 96 * 3.14

Answer area of the shaded part = 301.44

Answer area of the shaded part = 301.4 rounded to the nearest tenth

The second problem is done exactly the same way. Only the numbers have been changed. I will give you the answers to the main part of the problem and you can try and get what I got. If we disagree, be preparred to tell me what you got so I correct mine if it is wrong.

Outter Radius = 18 + 8 = 26

Area of outter circle =  pi * 26^2

Area of outter circle =  676 pi

Inner Circle area hole = pi * 18^2

Inner Circle area hole = 324 pi

Area of the shaded part = outter circle - inner circle

Area of the shaded part = 676 pi - 324 pi

Area of the shaded part = 352 pi

pi = 3.14

Area of the shaded part = 352 * 3.14

Answer: area of shaded part rounded to 1 decimal place = 1105.3

What is the value of x so that the mean is 5. 7, x, 5, 3, 2

Answers

Answer:

8

Step-by-step explanation:

The 'mean' is the same as the 'average'

( 7 + x + 5 + 3 + 2) / 5    =  5

 7+x+5+3+2 = 25

     x = 8

Points and their residual values are shown in the table. a 3-column table with 5 rows. the first column is labeled x with entries 1, 2, 3, 4, 5. the second column is labeled y with entries 2, 3.5, 5, 6.1, 8. the third column is labeled residual value with entries negative 0.4, 0.7, negative 0.2, negative 0.6. which residual value is the farthest from the line of best fit? 0.19 0.7 2 8

Answers

The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

What is residual value?

The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset.

Points and their residual values are shown in the table. A 3-column table with 5 rows.

 x                               1,     2,     3,     4,     5.  y                               2,   3.5,   5,    6.1,    8.Residual Value       -0.4, 0.7,  -0.2, -0.6   0

The simple regression line can be represented as,

[tex]\hat y=\alpha +\beta X+\hat e[/tex]

Here α is the constant, β is the slope and e is the residue.

The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.

Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

What is the length of the diagonal of the rectangle?

Answers

Answer:

Length of diagonal of the rectangle is 21.25 units.

Step-by-step explanation:

Here we are given Length of the rectangle 17 and Width 12.75. To find length of the diagonal of the rectangle we will substitute the value of length and width in required formula:

We know that,

[tex] \\ \: \: \dashrightarrow \: \: { \underline{ \boxed{ \pink{ \pmb{\mathfrak {Diagonal = \sqrt {(Length)^2 + (Width)^2 }}}}}}} \\ \\ [/tex]

Substituting the required values:

[tex] \\ \: \: \dashrightarrow\sf \: \: Diagonal = {\sqrt{(17)^2 + (12.75)^2}} \\ \\ [/tex]

[tex]\: \: \dashrightarrow\sf \: \: Diagonal = \sqrt{289 + 162.5625} \\ \\ [/tex]

[tex]\: \: \dashrightarrow\sf \: \: Diagonal = \sqrt{451.5625} \\ \\ [/tex]

[tex]\: \: \dashrightarrow \: \: \pink {\underline{ \boxed{ \pmb{\frak {Diagonal = 21.25}}}}} \\ \\ [/tex]

Hence,

Length of diagonal of the rectangle is 21.25 units.

Two bags, A and B, each contain only green marbles and red marbles.
There are 6 green marbles and 4 red marbles in bag A.
There are 8 green marbles and 2 red marbles in bag B.
One marble is going to be taken at random from bag A and placed in bag B.
A marble is then going to be taken at random from bag B.
Work out the probability that this marble will be a green marble. ​

Answers

Using it's concept, it is found that there is a 0.7818 = 78.18% probability that this marble will be a green marble. ​

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

There are two ways to end up with a green marble selected.

Green in bag A(6/10 probability) and in bag B(9/11 probability).Red in bag A(4/10 probability) and green in bag B(8/11 probability).

Hence, the probability that this marble will be a green marble is given by:

[tex]p = \frac{6}{10} \times \frac{9}{11} + \frac{4}{10} \times \frac{8}{11} = \frac{54 + 32}{110} = 0.7818 = 78.18\%[/tex]

a)If the amount was £200, how much money did she give to family?

Answers

Answer:  She gave a fraction of 1/4 to charity, and she gave $150 to family

Step-by-step explanation:  Ebony had a totaly of $200 dollars to start with to give away that means if she gave 3/4 of $200 to family that would mean she gave $150 dollars to her family

Now the other part of the question is how much of the total amount did Ebony give to charity now if I understand that part correctly then it wants you to give the fraction of the total which would be she gave 1/4 out of the $200 she had for family and charity which means she gave 1/4 of $200 which is $50 to charity

John has a bag of different colored marbles. He has 6 red marbles, 3 blue marbles, 7 yellow marbles, and 5 green marbles. If John reaches into the bag and randomly pulls out a marble, what is the probability that the marble will be blue? (If necessary, round to the nearest tenth.) (as a percent please!!)

Answers

Answer:

P(blue) ≈ 14.3%

Step-by-step explanation:

probability P is calculated as

P = ( favourable outcome ) ÷ ( total number of possible outcomes )

here favourable outcome is blue of which there are 3

number of possible outcomes is the total = 6 + 3 + 7 + 5 = 21

P(blue) = [tex]\frac{3}{21}[/tex] = [tex]\frac{1}{7}[/tex]

to convert to a percentage multiply the fraction by 100%
