convert 3400 to hours
60mins per hour, 60 seconds per minute
60*60=3600 sseconds per hour

3400/3600=17/18

convert feet to miles
63360/5280=12
12 miles per (17/18) hours
12/(17/18)

snow_lady [41]

Answer:

The z score for a wide receiver who dropped 13 footballs over the course of a season

Z = - 1.5

Step-by-step explanation:

Explanation:-

Given Population mean ' μ'= 16

Standard deviation of Population 'σ' = 2

Let 'x' be the Random Variable of Normal distribution

Given x = 13 foot balls

The z score for a wide receiver who dropped 13 footballs over the course of a season

$Z = \frac{x-mean}{S.D}$

$Z = \frac{13 -16}{2} = \frac{-3}{2} = -1.5$

Final answer:-

The z score for a wide receiver who dropped 13 footballs over the course of a season

Z = - 1.5
