15.87% of the population does not meet the minimum standards.
We use z-scores to find this probability:
z=(X-μ)/σ = (85-100)/15 = -15/15 = -1
Using a z-table (http://www.-table.com) we see that the area to the left of, less than, this is 0.1587. This is 15.87%.
Answer:
12/10 or 1 1/5
Step-by-step explanation:
1/2 = 5/10
7/10 + 5/10 = 12/10 or 1 1/5
Answer:
4,301,970
5,149,815
Step-by-step explanation:
The cost of a bicycle is 2895
Therefore the cost of 1486 bicycles is
= 2895×1486
= 4,301,970
A truck can carry 6785 kg of food
Therefore the amount in which 759 truckj can carry can be calculated as follows
= 6785×759
= 5,149,815
The volume of this container is 5990 feet³.
<h3>How to calculate the volume?</h3>
Volume of a cylinder = πr²h
π = 3.14
r = radius = 17.5/2 = 8.75
h = 24.5
The volume will be:
= πr²h
= 3.14 × 8.75² × 24.5
= 5990 ft³
Therefore, the volume of this container is 5990 feet³.

Answer:
The total nuber of hours that the battery can be used over its lifetime is 600.
Step-by-step explanation:
We use an infinite geometric series to solve this question.
The sum of all values of an infinite geometric series is given by the following equation:

In which
is the first term and r is the common ratio.
After each charging, a battery is able to hold only 97% of the charge from the previous charging.
This means that 
The battery was used for 18 hours on its first charge before it had to be recharged.
This means that 
What is the total number of hours the battery can be used over its lifetime?

The total nuber of hours that the battery can be used over its lifetime is 600.
