Solve 2(3x+6)=3(x-9)

Alisiya [41]

Answer:

-13

Step-by-step explanation:

<u>See steps below:</u>

2(3x+6)=3(x-9) ⇒ distribution
6x + 12 = 3x - 27 ⇒ grouping like terms
6x - 3x = -27 - 12 ⇒ simplifying
3x = -39
x= -39/3
x = -13 ⇒ answer

Researchers are studying the distribution of subscribers to a certain streaming service in different populations. From a random

Dahasolnce [82]

Answer:

$(0.17 - 0.27) \pm 1.65\sqrt{\frac{0.17*0.83 + 0.27*0.73}{200}}$ , that is, option C

Step-by-step explanation:

From a random sample of 200 people in City C, 34 were found to subscribe to the streaming service. From a random sample of 200 people in City K, 54 were found to subscribe to the streaming service.

This means that the proportions are:

$p_C = \frac{34}{200} = 0.17$

$p_K = \frac{54}{200} = 0.27$

Subtraction of proportions:

In the confidence interval, we subtract the proportions. So:

$p = p_C - p_K = 0.17 - 0.27$

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.
