Una linea di adattamento ottimale è una linea retta che rappresenta al meglio i dati su un diagramma a dispersione. Questa linea può passare attraverso alcuni dei punti, nessuno dei punti o tutti i punti
Step-by-step explanation:
Answer:
7x + 15x= 21x
Step-by-step explanation:
7x + 15x
= (7 + 15)x
= 22x
the circle is 5; the triangle is 2; and the square is 6
Answer: 1 11/15
Step-by-step explanation:
9/10 + 5/6
=
9 × 3
+--------
10 × 3
5 × 5
-------
6 × 5
=
27/30 + 25/30
=
27 + 25
-----------
30
=
52/30
=
52 ÷ 2
----------
30 ÷ 2
=
26/15
=
1 11/15
For this case we have the following expressions:
Rewriting the second equation we have:
It is observed that by multiplying the first equation by 2, the second equation is obtained.
Thus, the equations are linearly dependent and since the lines are equal then they are intercepted in infinite points. Therefore, the system has endless solutions.
