Find the Z score to the nearest hundred thousand satisfies the given condition 0.166 square units of the standard normal distrib
1 answer:
The sum of the total area of a distribution is equal to 1. In our problem, we have 0.166 square units to the left of our value, therefore, we have the following area on the right
Using a z-table, we can find the corresponding z-value for this area to the right
The corresponding z-score to this area is 0.97, however, this value is below the mean, therefore it is negative.
The coresponding z-value is

Answer:
Total Distance = 2 miles
Step-by-step explanation:
We know D = RT where
D is distance
R is rate (speed)
T is time
First Leg:
Rate = x mph
Time = 20/60 = 1/3 hour
Hence, D = RT, Distance = x * 1/3 = x/3 miles
Second Leg:
Rate = x - 1
Time = 30/60 = 1/2 hour
Distance = (x - 1) * 1/2 = (x-1)/2
Total distance is the sum of both the legs, hence,
Total distance = miles
Since both the distance are equal we can equate and solve:
Plugging this x = 3 into the total distance expression, we get:
Total distance, 2 miles
Let the women's height be AE and distance between the women and tower be AC.
Also let the height of tower be BC.
Now, clearly it is forming a triangle.
So, in triangle ABC,
Hence, BC = 59.5m
So, BD(total height of the tower)
Therefore, total height of the tower =
