Alex777 [14]

Answer: 60 pages left.

Step-by-step explanation:

Let the number of pages in the book be x.

As per given, we have

\dfrac14x+20=\dfrac13x\\\\\Rightarrow\ \dfrac{1}{3}x-\dfrac14 x=20\\\\\Rightarrow\ \dfrac{4-3}{12}x=20\\\\\Rightarrow\ \dfrac1{12}x=20\\\\\Rightarrow x=20\times12\\\\\Rightarrow x=240

\dfrac34 of total book = \dfrac34\times 240=180

Pages left = 240-180

= 60

Hence, 60 pages left.

Simplify the expression by using a double-angle formula 1-2sin^2(3theta)
NeTakaya
We know that:

\cos(2x)=1-2\sin^2(x)

Crank
The z-score corresponding to x = 27 is calculated as:
z = (x - mu)/SD, where mu is the population mean of 32 years, and SD = 4 years. Then,
z = (27 - 32)/4 = -1.25
From a z-table, the probability that x < 27 corresponds to the probability that z < -1.25:P(z < -1.25) = 0.1056
