*when looking at the intervals, order matters*

So these are the points of g(x):
(-2, 2)
(-1, 0)
(0, 2)
(1, 8)

And these are the answer choices:
a.) <span>The function is decreasing from x = 0 to x = 1. 
b.) </span><span>The function is decreasing from x = −1 to x = 0.
c.) </span><span>The function is increasing from x = 0 to x = 1.
d.) </span><span>The function is increasing from x = −2 to x = −1.

Let's take a look at the first answer choice. It says that from x = 0 to x = 1, the y is decreasing. Well, when x = 0, y = 2 (from the point) and when x = 1, y = 8. So a.) is in fact wrong. The function is increasing from x = 0 to x = 1, not decreasing.

Let's look at the second choice. It says that the function is decreasing from x = 0 to x = -1. Let' look at the two points when x = -1 and x = 0.</span>
(-1, 0)
(0, 2)
Well, starting from x = -1, the y is 0. And from 0, the y is 2. So the function is actually increasing at that interval. The second choice is incorrect.

And the third choice: from x = 0 to x = 1, the function is increasing. Look at the points.
(0, 2)
(1, 8)
The y starts at 2 then goes to 8. So the function is indeed increasing.

The third choice is correct! ^-^

(always double check all answers but I'll tell you right now the fourth one is incorrect)

Assume that when adults with smartphones are randomly selected, 54% use them in meetings or classes (based on data from an lg sm
GuDViN [60]
Answer: 0.951%

Explanation:

Note that in the problem, the scenario is either the adult is using or not using smartphones. So, we have a yes or no scenario involved with the random variable, which is the number of adults using smartphones. Thus, the number of adults using smartphones follows the binomial distribution.

Let x be the number of adults using smartphones and n be the number of randomly selected adults. In Binomial distribution, the probability that there are k adults using smartphones is given by

P(x = k) = \frac{n!}{k!(n-k)!}p^k (1-p)^{n-k}

Where p = probability that an adult is using smartphones = 54% (since 54% of adults are using smartphones). 

Since n = 12 and k = 3, the probability that fewer than 3 are using smartphones is given by

P(x \ \textless \  3) = P(x = 0) + P(x = 1) + P(x = 2)&#10;\\ \indent = \frac{12!}{0!(12-0)!}(0.54)^0 (1-0.54)^{12-0} + \frac{12!}{1!(12-1)!}(0.54)^1 (1-0.54)^{12-1} + \\ \indent \frac{12!}{2!(12-2)!}(0.54)^2 (1-0.54)^{12-2}&#10;\\&#10;\\ \indent = \frac{12!}{(1)(12!)}(0.46)^{12} + \frac{12(11!)}{(1)(11!)}(0.54)(0.46)^{11}+ \frac{12(11)(10!)}{(2)(10!)}(0.54)^2(0.46)^{10}&#10;\\&#10;\\ \indent = (1)(0.46)^{12} + (12)(0.54)(0.46)^{11}+ (66)(0.54)^2(0.46)^{10}&#10;\\ \indent \boxed{P(x \ \textless \  3) \approx 0.00951836732 }&#10;

Therefore, the probability that there are fewer than 3 adults are using smartphone is 0.00951 or 0.951%.

Answer:

(2x + 15)° = 180°

2x = 180 - 15

2x = 165

x = 165/2

x = 82.5
