Answer:
- 0.83
- 0.9
- steeper than
- slower than
Step-by-step explanation:
Letting t=1 in Ted's equation, we find that he climbs 5/6 stairs in 1 second. As a decimal, 5/6 ≈ 0.83.
Michael climbs 9 stairs in 10 seconds so his rate is ...
... (9 stairs)/(10 seconds) = (9/10) stairs/second = 0.9 stairs/second
Michael's graph will be a line with a slope of 0.9; Ted's graph will be a line with a slope of about 0.83, so the line on Michael's graph is steeper.
Ted climbs fewer stairs per second, so his rate is slower than Michael's.

<em>Comment on the problem</em>
You're being asked to compare two different rates that are associated with two different people. First the comparison is one way, then it is the other way. This can be confusing. It might be helpful to draw and label a simple chart to help you keep it straight. (The attachment is such a chart scribbled on a bit of scratch paper. It is sufficient for the purpose.)
First, let's write an expression to represent this:
Now we'll simplify it:
Answer:
a. True
Step-by-step explanation:
We have been given a statement. We are asked to determine whether the given statement is true or false.
Statement: A normal distribution is symmetric; therefore the probability of being below the mean is 0.50 and the probability of being above the mean is 0.50.
We know that normal distribution is continuous probability distribution.
We know that the total area under a normal distribution curve is equal to 1. We also know that mean represents center of the normal distribution curve.
The half area will be below center and half area will be above center.
Since 0.50 is half of 1, therefore, the probability of being below the mean is 0.50 and the probability of being above the mean is 0.50 and given statement is true.
Answer:
15 degrees lower
Step-by-step explanation:
When you are trying to find the difference between a negative and positive number, add both numbers and you will get the difference. In this case it was 15.
Sorry, math isn't my strongest suit, but i hoped this helped!
The second value: 5.099 is the lesser known value
