The correct answer is C.
When you have two fractions being divided, you can flip the second one and then multiply straight across. So in this case the top of your final answer would be the numerator of the first fraction multiplied by the denominator of the second:
(3x - 6)(2x - 1) = 6x^2 - 15x + 6
Then the bottom of your answer would be the denominator of the first fraction multiplied by the numerator of the second one:
x^3(x - 2) = x^4 - 2x^3
45+8.3 = 53.3
<span>45 - (2(8.3)) = 28.4
The value is </span> 28.4 <span>that is –2 standard deviations away from the mean.</span><span>
</span>
Area = pi * r^2
A = 3.14 * 7.6^2
A = 181.37
In short, Your Answer would be 181.37 cm^2
Hope this helps!
An average is just the total attendance numbers / the number of performances.
Let's let the number of people in the third show be equal to x so we can write this as a formula, it's easier to read. x is just "some number we don't know"
The average is
Average=Total attendance/3
So
3000=(2580+2920+x)/3
So let's multiply by that 3 on both sides, make x easier to find
Average*3=2580+2920+x ( * means multiplied)
The average is 3000
So
2580+2920+x=3000*3
2580+2920+x=9000
Then we subtract those other attendances to get x on its own.
x=9000-2580-2920
x=3500
