Answer:
221 minutes
Step-by-step explanation:
His goal is 8 minutes or less for every mile during the marathon.
8 x 52 = 416
That gives him 416 total minutes to complete the marathon goal.
He already ran the first half in 195 minutes, so we do this to find the time for the other half:
416 - 195 = 221
He has 221 minutes in the second half of the marathon to meet his goal.

In this problem, we have that:

So



The standard deviation is 5.29 kg.
Answer:
11 minutos.
Step-by-step explanation:
En las Olimpiadas de Matemáticas, la hora de inicio del evento se expresa en una ecuación simple: 2x + 6 = x + 17 ¿A qué hora comenzó el evento?
La hora en que comienza el evento en los juegos olímpicos se representa como x
Por tanto: 2x + 6 = x + 17
Recopilar términos similares
2x - x = 17 - 6
x = 11 minutos
Por lo tanto, los eventos comienzan en 11 minutos.
the answer would be 0.800375 but when you round it to the nearest tenth it would be 0.8
