Answer:
-10x⁶+20x⁵+4x⁴-46x³+16x²+12x-24
Step-by-step explanation:
(-5x³ + 2x - 4)(2x³ - 4x² + 6)
= -10x⁶ + 4x⁴ - 8x³ + 20x⁵ - 8x³ + 16x² - 30x³ + 12x - 24
= -10x⁶+20x⁵+4x⁴-46x³+16x²+12x-24
(-5x³ + 2x - 4)(2x³ - 4x² + 6)
Is same as
(2x³ - 4x² + 6)(-5x³ + 2x - 4)
Because multiplication is commutative.
a×b = b×a
The interval given was 33% to 37%
This means that subtracting the margin of error from the percentage of the population that visit the library once a year gives the lower end and adding the margin of error to the percentage of the population that visit the library once a year gives the upper end
Let x denote margin of error and y denotes the percentages of the population that visit the library once a year
we can get the following equations and solve for the values of x and y
Adding eqn1 and eqn2 to gives
Putting the value of y into any of the equations
Thus, the margin of error is
Therefore we enter 2 in the box
