Polygon ABCD reflects about line to make polygon EFGH. What is the length of ? A. 2 units B. 2.2 units C. 3 units D. 3.2 units
1 answer:
Answer:
A) LEngth of FG is 2 units
Step-by-step explanation:
Considering the diagram attached below.
Reflection of any polygon does not affects its length.
As it is given both polygons are reflection of each other so their sides are congruent.
AB ≅ EF = 3 units
BC ≅ FG = 2 units
CD ≅ GH = 2.2 units
DA ≅ HE = 3.2 units

A) See picture for the table.
To make the table, multiply 47774 by 1.5% to get total that have diabetes and multiply 5855 by 2.5% to get total unemployed that have it, then using subtraction fill in the other squares of the table.
B)
Hypothesis:
H0: No association between employment and diabetes.
H1: Association between the two
Using a graphing calculator or Excel, run a chi-test.
Chi squared equals 31.844 with 1 degrees of freedom.
The two-tailed P value is less than 0.0001
With this information we can reject the null hypothesis and conclude there is an association between diabetes and employment.
C)
Although there is a statistical significance, there really is no practical significance between an incidence rate of 1.5 or 2.5%
