<span>≈ 7.734% </span>
After the first cut: 3
after the 2nd cut: 9 or 3²
after the 3rd cut: 27 or 3³
after the 4th cut: 81 or 3⁴
after the 7th cut: 3⁷ = 2187 small pieces of paper
Step-by-step explanation:
y = -f(x)
so, everything is mirrored around the x-axis.
what was below the x-axis, is now above the x-axis, what was above is now below. and what was on the x-axis, is still on the x-axis.
pick the corner points of f(x), their x-values stay the same, their y-values flip the sign. the points on the x-axis (y = 0) stay the same of course.
and then connect the points, so that the curve is upside-down to the original.
well, this is just a matter of simple unit conversion, so let's recall that one revolution on a circle is just one-go-around, radians wise that'll be 2π, and we also know that 1 minute has 60 seconds, let's use those values for our product.

A. the probability that the sum is 11,given that the first number cube shows a 6
