Answer:

879.65

Step-by-step explanation:

The area of the larger circle is

A = pi r^2

A = pi (17 ^2)

Using the pi button

A = 907.9202769

The area of the inner circle

A = pi (3)^2

A = 9pi

A =28.27433388

Subtracting the smaller circle from the larger circle

907.9202769 - 28.27433388

879.645943

Rounding to two decimal places

879.65

irga5000 [103]

Answer:B

Step-by-step explanation:

Given

Every student secure same average score

Standard deviation is denoted by \sigma

$\sigma _A=3.12$

$\sigma _B=0.27$

$\sigma _C=13.45$

$\sigma _D=6.45$

Consistency is criteria of acceptance then Student should be selected the standard deviation is least for student B.

Standard deviation tells how a data varies from mean Position .

More Deviation from mean indicates less consistency .

Solve this system of linear equations. separate x and y values with a comma. 7x=-67-11y 5x=-73-11y

Aleks [24]

Answer:

3, -8

(x is equal to 3 and y is equal to -8)

Step-by-step explanation:

The system:

{ 7x=-67-11y

{ 5x=-73-11y

Finding a value for x:

7x=-67-11y -> x = $-\frac{67}{7}$ - $\frac{11y}{7}$

Solving for y by plugging in our x:

[Equation] 5x = -73 -11y

[Plug-in] 5( $-\frac{67}{7}$ - $\frac{11y}{7}$ ) = -73 -11y

[Distribute the 5] $-\frac{335}{7}$ - $\frac{55y}{7}$ = -73 -11y

[Multiply by 7] 7 ( $-\frac{335}{7}$ - $\frac{55y}{7}$ ) = (-73 -11y) 7

[Simplify] -335 - 55y = -511 - 77y

[Add 335 and 77y to both sides] 22y = -176

[Divide by 22] y = -8

Plug in our y to solve for x:

5x = -73 -11y

5x = -73 -11(-8)

5x = -73 + 88

5x = 15

x = 3

Have a nice day!
