Answer: 
Step-by-step explanation:
Let p be the population proportion of adults who were surveyed are current smokers.
Given claim : Abigail, who works for a region's department of health, is looking for evidence that the percentage of adults in the region who are current smokers has decreased from 15.8% in 2015.
i.e. 
Since the alternative hypothesis takes unequal sign .
Then , the null and alternative hypotheses for this hypothesis test will be :_

The conditional relative frequency presents the result of the survey that conveys information about the programming and the audience.
- The best description of the value 0.357 in the table is; <u>Given that the program was targeted at adults, there is a 37.5% chance that it was recorded</u>.
Reasons:
The table is presented as follows;
![\begin{tabular}{|c|c|c|c|}&Live&Recorded&Total\\Adult&0.625&0.375&1.0\\Children&0.5&0.5&1.0\\Total&\approx 0.583&\approx 0.417&1.0\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%7B%7Cc%7Cc%7Cc%7Cc%7C%7D%26Live%26Recorded%26Total%5C%5CAdult%260.625%260.375%261.0%5C%5CChildren%260.5%260.5%261.0%5C%5CTotal%26%5Capprox%200.583%26%5Capprox%200.417%261.0%5Cend%7Barray%7D%5Cright%5D)
Based on the given table, we have that the programs are categorized based on the intended audience.
Therefore, the 0.375, indicates that 37.5% of the program targeted at adults are recorded.
Therefore, the correct option is;
<u>Given that the program was targeted at adults, there is a 37.5% chance that it was recorded.</u>

So base on the question, that states the weight of Rex from last year to the present, and find its rate if change or percentage of change. To calculate the percentage you must first subtract the said weight in the present to its past then divide it by its past weight then multiply it by 100. So the percentage would be 15 %. I hope this would help
Answer:
Step-by-step explanation:
-3i √(-40) = -3i √40i² ...(i² = - 1)
= -3i √40 i
-3i √(-40) = 3√40
Change 48% to 0.48
0.48 x 18 = 8.64
rounded would be 9
