Thinking about the areas of a Standard Normal Distribution, if a z value is negative, is the area to the left of z less than 0.5
000, greater than 0.5000 or equal to 0.5000?
1 answer:
A typical plot of the standard normal distribution is shown in the figure below.
The curve is symmetric about z = 0, and the total area under the curve is 1.
It follows that if the value of z is negative, the area to the left of z will be less than 0.5.
Answer: The area to the left of z is less than 0.5000

Answer:
(A)6 kilometers
Step-by-step explanation:
First, we determine the value of a using Pythagoras Theorem.
Therefore:
Distance along the long route = 8 + 15 =23 km
Distance along the shortcut =17 km
Difference =23-17 =6km
Therefore, Mr. Jones bikes 6km less when he takes the shortcut instead of the long route.
