Factor the expression using the GCF. 18x + 24y.
Georgia [21]
Answer: 6(3x + 4y)

1. Find the GCF (the largest number that goes into both 18x AND 24y). This would be 6.

2. Factor out the 6 by dividing each of the terms by the GCF
18x/6 = 3x
24y/6 = 4y

3. Write as a factored expression
6(3x + 4y)

Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G (1,3) H (4,3) J (5,1) and K (2,1
Basile [38]

Answer: (3,2)

Step-by-step explanation: <u>Diagonal</u> is a line connecting two opposite points of a form. In parallelograms, there two diagonals and they bisect each other, i.e., the point where the diagonals meet divide them into two segments with the same measure. In short, diagonals meet at their midpoint.

The way to determine midpoint is given by

(x,y) = {\frac{x_{1}+x_{2}}{2} },\frac{y_{1}+y_{2}}{2}

(x,y) = {\frac{1+5}{2} },\frac{3+1}{2}

(x,y) = (3,2)

The coordinates where diagonals of parallelogram GHJK intersect are (3,2).

The 2016 Minneapolis Resident Survey was a questionnaire that the City of Minneapolis issued to its randomly chosen residents. I
sukhopar [10]

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.
