Answer:
13, 21
Step-by-step explanation:
Add 8 to the next number from the left to the right.
Solution: We are given the population mean 
Now, in order to find which shift's mean is closest to population mean, we will find the mean of each shift.
The mean of shift 1 is:
The mean of shift 2 is:
The mean of shift 3 is:
The mean of shift 4 is:
We clearly see the mean of shift 2 is close to the population mean. Hence the option B) Shift 2 is correct.
Answer:
a/2 + b unidades
Step-by-step explanation:
Mi primera lengua es ingles (tienes paciencia por favor). Se da que la parte inferior es a/2 unidades. La parte anaranjada tiene un lado que es b/2, entonces todos los lados son b/2 tambien. Entonces el lado del derecho es b/2. La izquierda es b/2 tambien ( se da eso). Entonces el perimetro del triangulo amarillo es a/2 + b/2 + b/2 = a/2 + b unidades.
