Because all sides of a square are equal. Regular polygons always have equal sides.
43568 x 32159 = 1,401,103,312
<h3>The system of equations has infinitely many solutions</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
y = x + 2 ------ eqn 1
-3x + 3y = 6 -------- eqn 2
Solve the system of equations by substitution method
Substitute eqn 1 in eqn 2
-3x + 3(x + 2) = 6
-3x + 3x + 6 = 6
-3x + 3x = 6 - 6
0 = 0
If we end up with the same term on both sides of the equal sign, then we have infinite solutions
Thus the system of equations has infinitely many solutions
1 × 28 = 28
14 × 2 = 28
4 × 7 = 28
Answer:
I. Mean = 15
II. Median = 15
Step-by-step explanation:
<u>Given the following data;</u>
Total number of students = 8
x = 18, 10, 20, 18, 12, 19,12, 11
F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11
F(x) = 120
To find the mean;
Mean = F(x)/n
Mean = 120/8
Mean = 15
To find the median;
<em>Median refers to the middle number of a sorted data</em>.
x = 10, 11, 12, 12, 18, 18, 19, 20
Middle numbers = 12 and 18
Median = (12 + 18)/2
Median = 30/2
<em>Median = 15</em>
