Answer: I and III
Step-by-step explanation:
We observe in the case provided that the researcher, who has no interest in the population to intervene, is going to carry out surveys to assess whether the neighborhood is a good place to live, obtaining the following conclusions:
i. The Minneapolis Resident Survey was an observational study.
ii. The Minneapolis Resident Survey was an experiment.
iii. The figure 50.1% is a descriptive statistic for the sample.
iv. The figure 50.1% is a statistical inference for the population.:By estimating the sample, obtained by a lower percentage of the total of the respondents, it is known that with a 95% confidence interval that the rating obtained from the respondents considering that the neighborhood is a good place to live was found between 0.44 and 0.50, taking this interval as a statistical inference for the population.
The correct answer is I and III, since in this study no interventions were made to the population and only one observation of a characteristic of the neighborhood was made and in III we know that the descriptive statistic only describes data and summarizes it, which is a of the ways to display the data from the descriptive survey.
<u>Given</u>:
Let the two numbers be x and y.
Two numbers multiply to be -7 and add to be -6.
This can be written in equation as,
and

<u>Value of the two numbers:</u>
Let us determine the value of the two numbers using substitution method.
Substituting
in the equation
, we get;

Simplifying, we get;




Thus, the values of x are x = 1,-7
When x = 1 , the equation
becomes 
When x = -7, the equation
becomes 
Therefore, the two numbers are 1 and -7

Answer:
A
Step-by-step explanation:
To turn a fraction into a percent, you divide the numerator by the denominator.
8 divided by 9 = .8 repeated
To turn it into a percent, you move the decimal to the right 2 spaces.
.8 turns into 88.8 repeated
Then you round to the nearest hundredth
88.8 repeated rounds to 88.89.
