Answer:
2
Step-by-step explanation:
If you square -4 it equals 16 and if you take that number and divibe it by 8 you get 2.
Answer:
The researcher should use correlation analysis for his studies.
Step-by-step explanation:
What is correlation?
Correlation is a statistical tool used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two.
Types of correlation
1. Positive, Negative or Zero Correlation:
2. Linear or Curvilinear Correlation:
3. Scatter Diagram Method:
4. Pearson's Product Moment
Coefficient of Correlation:
5. Spearman's Rank Correlation
Coefficient:
Answer:
600 students attend the school.
Step-by-step explanation:
495-7=488
488/4=122
488+122= 600
Answer:
D) 10 units
Step-by-step explanation:
Opposite sides of a parallelogram are congruent.
__
<h3>setup</h3>
The relation between opposite sides tells you ...
BC = AD
2x = x +5
<h3>solution</h3>
x = 5 . . . . . . . subtract x from both sides of the equation
We want the length of AD, which is ...
AD = x +5 = 5 +5
AD = 10

<em>Additional comment</em>
Often, it seems like the question is answered once the value of x is found. Here, finding the value of x is an <em>intermediate step</em>. The value of x is needed in order to be able to answer the question about <em>the value of an expression involving x</em>.
0.25 = 25/100
to simplify 25/100, divide 25 from both the numerator and denominator.
25/25 = 1
100/25 = 4
1/4 is the simplest form
C. 1/4 is your answer
