Ok, im guessing that this is all about mean
First mean is just adding everything up for example:
5+5+10+10+5
so the answer is 35, but that isnt completely finished you need to divide 35 by 5, or how many numbers were added then you get the mean for my example the mean is 7

ACTUAL PROBLEMS
1. 10+15+14+8+18+11+12+12+10+10+17+16 = 153
153/12= 12.75
2. 16.4+17.1+17.4+18.1= 69 B)
69/4=17.25
3. 11+15+19+17+23+20+17+13+18+21=174
174/11=15.8181818182
4. 21+25+36+16+32= 130
130/5=26

Hi there!

Use the chain rule:
f(g(x)) = f'(g(x)) · g'(x)
Thus:
dy/dx sin(x) = cos(x)
dy/dx cos(x) = -sin(x)
Use the chain rule format:
f(x) = sin(x)
g(x) = cos(x)
cos(cos(x)) · (-sin(x))
-sin(x)cos(cos(x))

Step-by-step explanation:
Los movimientos bancarios de Santiago se representan matemáticamente teniendo en cuenta que consignar es sumar y retirar el restar. Por lo tanto podes expresar los movimientos bancarios de la siguiente manera:
- Lunes → + 300.000
- Martes → -120.000
- Miércoles → -95.000
- Jueves → +80.000
Al realizar la sumatoria se obtiene:
+300.000 - 120.000 - 95.000 + 80.000 = + 165.000
En la semana Santiago obtiene en su cuenta bancaria $165.000
