r-ruslan [8.4K]

Answer:

This stuff is quite easy in reality. Here's a little example including your numbers.

63-x=62; solve for x\\\\63-x-63=62-63\\\\-x=1\\

by this point we are left with simplifying it. Since it's a double negative we get a positive. Thus x=1

The number of days each licensed driver in Marion County uses a commuter rail line annually is normally distributed with mean 66
alexira [117]

Answer:

31.5 days

Step-by-step explanation:

We.solve using z score formula

z-score is is z = (x-μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

The 5th percentile z score = -1.645

Mean = 66

Standard deviation = 21

Hence:

-1.645 = x - 66/21

-1.645 × 21 = x - 66

-34.545 = x - 66

-34.545 + 66 = x

x = 31.455 days

Approximately to the nearest round integer

= 31.5 days

Therefore, driver use a commuter rail line 31.5 days annually to be in the top 5% of rail users
