The length of time it takes to find a parking space at 9 A. M. follows a normal distribution with a mean of 6 minutes and a standard deviation of 3 minutes. Eighty percent of the time, it takes more than how many minutes to find a parking space

And if we solve for a we got

Eighty percent of the time, it takes more than 8.526 how many minutes to find a parking space

Step-by-step explanation:

Let X the random variable that represent the lenght of time it takes to find a parking space of a population, and for this case we know the distribution for X is given by:

Where and

For this part we want to find a value a, such that we satisfy this condition:

  (a)

  (b)

We want to find a value who accumulate 0.80 of the area on the left and 0.2 of the area on the right it's z=0.842.

If we use condition (b) from previous we have this:

Using this formula we have:

And if we solve for a we got

Eighty percent of the time, it takes more than 8.526 how many minutes to find a parking space

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
