Values between negative two and positive two standard deviations from the mean are considered

Question solve: \( -3 n-105=4 n \)

If \( \frac{2}{3} \) of a number is 20 less than the original number, what is the original number?

Buatlah grafik fungsi berikut: 1. \( y=x^{3}+x^{2} \) 2. \( y=(x+1)^{3}+(x+1)^{2} \) 3. \( y=x^{3}+x^{2}-2 \) 4. \( y=(x+1)^{3}+(x+1)^{2}-2 \) 5. \( y=\cos \left(x-\frac{\pi}{2}\right) \) 6. \( y=3 \cos \left(\frac{x}{2}\right) \)

There are two functions that can be used to describe the percent of Americans 25 and older who have completed an associate's degree or higher. For both functions \( f(x)=0.72 x+35.2 \) and \( g(x)=0.04 x^{2}+0.47 x+34.9, x \) is the number of years since 2010, and any \( y \) (or \( f(x) \) or \( g(x)) \) is the percent of Americans 25 and older who have completed an associate's degree or higher. Assume that the trend of \( g(x) \) continues. Find \( g(18) \) and describe in words what this means.

Solve: \( -86=-8 y+2 \)
