Answer:
The probability is 2.2%
Step-by-step explanation:
The probability that a randomly selected adult uses the telephone in classes is always equal to 0.48.
If x represents the number of adults selected from among the 8 that the telephone uses in classes, then x is a discrete random variable that follows a binomial distribution, with:
p = 0.48
q = 0.52
n = 8
We want to find the probability of x = 5

The probability is 2.2%
Answer:
Step-by-step explanation:
The standard form of a circle is

If we are given x and y as 0 and 5 respectively, and we are also told that the center is (0, 0), our h and k are both 0. Filling in x, y, h, and k we can find the radius. So let's do that:
and
so
Our circle's equation is
Since the point in question, (4, 4), lies in the first quadrant, we will concentrate on that quadrant only. To fall within the circle, we can set up an inequality and test the point (4, 4). If it lies ON the circle then the equality would be true. Let's try that first:

Obviously, 16 + 16 does not equal 25, so that point (4, 4) does not lie ON the circle. In fact from that statement alone, we can determine that the point lies outside the circle because

If the inequality < were true then the point would lie inside.
Answer:
x = 5/2
Step-by-step explanation:
4x - 1/2 = x +7
4x - 1/2 - x = 7
4x - x = 7 + 1/2
3 x = 15/2
x = 5/2
