Question

Diego's goal is to walk more than 70,000 steps this week. The mean number of steps that Diego walked during the first 4 days of the week is 8,019.If the mean number of steps Diego walks during the last 3 days of the week is 12, 642, will Diego reach his goal of walking more than 70,000 steps this week? Explain your reasoning.

Answer 1

Diego goal was walk more than 70000 steoes

And in average in the first 4 days he walks 8019 steps

The expected mean number of steps for the next 3 days is 12642 then we can do this:

8019*4 + 12642*3= 32076 +37926 = 70002

then since 70002 > 70000

We can conclude that Diego can reach the goal for this case
