First we must find the LCD or Least common Denominator of these two fractions.6 is the LCD.1/2=3/6 and 1/3=2/6.( 3/6 - 2/6=1/6 or 2/3)
It's not 100% clear what you're asking for here.
If you begin with <span>f(x) = sin x, and write the new function g(x) = sin (x-pi/2), you get
g(x) = sin x cos pi/2 - cos x sin pi/2 = -cos x
This has a graph obtainable by shifting the graph of sin x pi/2 units to the right.
h(x) = sin (x+pi/2) has a graph obtainable by shifting the graph of sin x pi/2 units to the left.</span>

Answer:
0.8554 is the probability that the proportion of students living in dormitories is between 0.70 and 0.85
Step-by-step explanation:
We are given the following in the question:
Proportion of students who live in dormitories = 80%
Sample size, n = 80
Thus, the number of students follow a binomial distribution,
We use normal approximation to the binomial distribution to find the probability.
Parameters of Normal distribution:
We have to find the probability that the sample proportion (the proportion living in the dormitories) is between 0.70 and 0.85.
Thus, 0.8554 is the probability that the proportion of students living in dormitories is between 0.70 and 0.85
