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.
Answer:
a is true
Step-by-step explanation:
the y intercept of function a is -2 while on b it is -5
Y=mx+b
2y-3x=7
2y=3x+7
y=3/2x+7/2
slope(m) = 3/2
In order to find the Y intercept you have to have at least one pair of coordinates from the line and plug it into the slop intercept formula OR you can just look at y=3/2x+7/2 on a graph to see where the line crosses the y-axis with the x value of zero , unfortunately I don't have a graphing calculator and you did not provide coordinates but hopefully this helped c: !
1. 3(p+q)=p
3p+3q=p; 3p-p=3q; 2p=q so p=q/2
2. 4a=2b-7
2b=4a+7 so b=(4a+7)/2
when a=3 , b=(12+7)/2=19/2=9.5
3. d=rt; r=d/t
4.( 2x15)+(2xwidth)=90
2x width=90-30
width =60/2=30
Are you sure that is the full question? You can't distribute any of it that's just a simple multiplication problem. But if that is the whole equation than your answer is 128
