For this case we can make the following rule of three:
23000 -------> 100%
x --------------> 180%
Clearing the value of x we have:
x = (180/100) * (23000)
x = 41400
Answer:
you would expect about:
a) 41,400 responses
Use grid paper to find the median of the data. 9, 7, 2, 4, 3, 5,9,6,8,0,3, 8

Answer:
5.5
Step-by-step explanation:
0,2,3,3,4,5,6,7,8,8,9,9
there are to middle numbers
add then together (5 and 6)
which makes 11
divide 11 by 2
5.5
1)
2x^2 - 13x - 24 = 0;
the discriminant is : ( - 13 )^2 - 4 * 2 * ( -24 ) = 169 + 192 = 361 = 19^2 => we have two different rational-number solutions ;
2)
[ -2( x + 2 ) - 3( x - 5 ) ] / [ ( x - 5 )( x + 2 ) ] < 0 <=>
( -5x + 11 ) / [ ( x - 5 )( x + 2 ) ] < 0
We have 2 situations :
a) - 5x + 11 < 0 and ( x - 5 )( x + 2 ) > 0 => x∈ ( 11 / 5 , + oo ) and x∈( -oo, - 2 )U
( 5 , + oo ) => x∈( 5, +oo);
b) - 5x + 11 > 0 and ( x - 5 )( x + 2 ) < 0 => x∈(-oo, 11/5) and x∈( -2, 5 ) =>
x∈( -2, 11/5 );
Finally, x∈ U (-2, 11 / 5 ) U ( 5, +oo).
Answer:
C. I > 4 (or x > 4)
Step-by-step explanation:
first multiply 8 and (x - 5)
8(x– 5) – 3x > -20 -----> (8 * x) - (8 * 5) = 8x - 40 - 3x > -20
add like terms
8x - 40 - 3x > -20 -----> 8x + -3x = 5x - 40 > -20
combine -40 and - 20
5x - 40 > -20 ----> -20 + 40 = 5x > 20
Then finally divide
5x > 20 -----> (5x/5) > (20/5) = x > 4
