Answer:

Area of Shaded Area = 18.3

Step-by-step explanation:

P.S - The exact question is -

Given - In the following diagram, a quarter circle has been constructed using an isosceles right triangle whose legs measure 8 inches.

To find - Which of the following represents the area of the shaded region, rounded to the nearest tenth of a square inch?

Proof -

We know that,

Area of a quarter circle = [tex]\frac{1}{4} \pi r^{2}[/tex]

Also,

We know that ,

Area of isosceles Triangle = [tex]\frac{1}{2}*Base*Height[/tex]

Now,

Given that,

Radius of quarter circle = 8 inches

Base of Isosceles Triangle = 8 inches

Height of Isosceles Triangle = 8 inches

∴ we get

Area of a quarter circle = [tex]\frac{1}{4} \pi (8)^{2}[/tex] = 16[tex]\pi[/tex]

Area of isosceles Triangle = [tex]\frac{1}{2}*8*8[/tex] = 32

Now,

Area of Shaded area = Area of a quarter circle - Area of isosceles Triangle

                                 = 16[tex]\pi[/tex] - 32

                                 = 50.265 - 32

                                 = 18.265 ≈ 18.3

⇒Area of Shaded Area = 18.3

The solution is Option B.

The value of the equation is x = 2

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

x + 5 = 7   be equation (1)

On simplifying the equation , we get

Subtracting 5 on both sides of the equation , we get

x = 7 - 5

x = 2

Therefore , the value of x is 2

Hence , the equation is x = 2

Answer: $46.08

Step-by-step explanation:

Find the surface Area of the box

the bases are 12*12= 144 times 2 bases 144*2= 288

The area of each side is 12*18=216 times 4 sides 216*4=864

add the totals together to find the total surface area 288+864=1152

total surface area is 1152 inches. Multiply by the cost per square inch

1152*.04= 46.08

Answer:

Hello your question is poorly written the complete question is attached below

answer :

a) H0 : p1 = p2

  Ha : p1 ≠ p2

b)  Z = -0.58

c) P-value =  0.561915

d) we will reject the Alternative hypothesis

Step-by-step explanation:

For sample 1 ;  n1 = 254 , x1 = 28

For sample 2 ; n2 = 301 , x2 = 38

level of significance ∝ = 0.01

P1 = X1 / n1 = 28 / 254  = 0.1102

P2 = X2 / n2 = 38 / 301 = 0.126

a) Determine the null and alternate hypothesis

H0 : p1 = p2

Ha : p1 ≠ p2

b) Determine Test statistic

we perform a Z-statistic to test the hypothesis

Z = [tex]\frac{p1-p1 }{\sqrt{( p(1-p)*(\frac{1}{n1}+\frac{1}{n2}) ) } }[/tex]  -------- ( 1 )

p =  ( x1 + x2 ) / ( n1 + n2 )

= ( 28 + 38 ) / ( 254 + 301 ) = 0.1189

Where: p = 0.1189 , p1 = 0.1102 , p2 = 0.126 ( input values into equation 1 )

∴ Z = -0.58

c) Determine P-value

P-value =  0.561915 ( using excel function )

d) conclusion : since p-value > 0.01 ( level of significance ) we do not reject the null hypothesis.  therefore it proves that p1 = p2

Answer:

hello your question has some missing information attached below is the missing information

answer : mean ratio of estimate = 117.62

              standard error ( SE ) = 3.9765

Step-by-step explanation:

Given data : n = 20,  μx = 10.3  , N = 1132

∑ age ( yi) = ( 125 + 119 + --------- + 99 ) =  2148

∑ ( Y - rX)^2 = 6116.728

mean of age ( y ) = ∑ y / 20 =  2148 / 20 = 107.4

mean of diameter ( x ) = ∑x /20 = 188.1 / 20 = 9.405

∴ ratio estimate  = y /x = 107.4 / 9.41 = 11.4195

i) The mean of ratio estimate

= 11.4195 * μx  = 11.4195 * 10.3 = 117.6204

ii) determine the standard error ( SE )

calculate ; [tex]s^{2} _{r}[/tex] = 1 / ( n-1 ) *  ∑ (Y - rX)^2  = 1/19 ( 6116.728 ) = 321.933

Var (  μr ) = [ ( N - n ) / N*n ]*[tex]s^{2} _{r}[/tex]  =  [ ( 1132 - 20 ) / (1132*20) ] * 321.933

               = 15.81226

therefore the SE = √15.81226 ≈ 3.9765

Answer:

area = 220.5 ft²

Step-by-step explanation:

2(Length) + 2(10.5) = 63 feet

2L + 21 = 63

subtract 21 from each side of the equation:

2L = 42

divide both sides by 2:

L = 21 feet

area = L x W = 21 x 10.5 = 220.5 ft²

Answer:

A = 220.5 ft

Step-by-step explanation:

[tex]2(Length) + 2(10.5) = 63 feet\\[/tex]

[tex]2L + 21 = 63\\[/tex]

[tex]63 - 21[/tex]

[tex]2L = 42[/tex]

[tex]42/2[/tex]

L = 21 feet

[tex]A=l * w[/tex]

[tex]21 x 10.5 = 220.5 ft^{2}[/tex]
