Answer:
The Z score of the person is -3.09.
Step-by-step explanation:
The standard normal deviate (Z) for a normal distribution is given by
where,
X = the value of observation
is mean of the observations and
σ = standard deviation of the score
Applying values we get
Answer:a)117 hours b)4.875days.
Step-by-step explanation:
Using the formula
Speed =Distance / Time
Given Distance = 3 3/5 -mile
and Speed=2/65 miles per hour.
Time =Distance / Speed
Time = (3 3/5)/(2/65)
Time =18/5÷2/65
Time =18/5 x 65/2 =117 hours
Now 24 hours =1 day
therefore 117hours =(117hours x 1 day )/ 24 =4.875days.
The first thing you should know is that by definition:
d = v * t
Where
d: distance
v: speed
t: time
We then have to clear the time:
t = (d) / (v)
Substituting the values:
t = (6000) / (200)
t = 30 minutes
Answer:
It will take a raindrop to travel 6000m about:
t = 30 minutes
