Answer: 0.87 times per second (Or 52.2 times per minute)
Step-by-step explanation:
You need to make the conversion from minutes to seconds.
Remember that 1 minute has 60 seconds. Then 20 minutes to seconds is:
Find the number of times the heart beats in 1 second when it is rowing:
Find the number of times the heart beats in 1 second when it is resting:
Then the difference is:
(Or 52.2 times per minute)
Answer:
Odd numbers.
Step-by-step explanation:
Closed under addition means you will able to take any two numbers from whatever set is mentioned and add them to get a number in that same set.
(If I say counting numbers, I'm still talking about the natural numbers.)
So let's look at the natural numbers {1,2,3,4,5,6,...}.
1+1=2
1+2=3
1+3=4
...
6+19=25
Let a and b be counting numbers.
a+b is still going to be a counting number.
You will always get a counting number when adding two counting numbers. So the counting numbers (also known as the natural numbers) is closed under addition.
Let's skip down to odd numbers because the other sets are similar to the first.
Let's add a pair of odd numbers.
3+5=8
8 is not odd so the odd numbers are not closed under addition because we will not always get an odd number. In fact, you will never get a odd number, but the thing is you just need one example to show it is not closed.
(2k+1)+(2a+1)
2(k+a)+2
2(k+a+1) is even so adding two odds will always give you an even.
The statement: "Kiley bought a platter for $ 19 and several matching bowls that were $ 8 each. What is the cost before tax?" shows discrete graph.
<h3> </h3><h3>What is Discrete Graph?</h3>
A discrete graph is one with scattered points. They may or may not show a direction or trend. They don't have data in between the points already given.
Here only first option shows a graph with scattered point.
Thus, the statement: "Kiley bought a platter for $ 19 and several matching bowls that were $ 8 each. What is the cost before tax?" shows discrete graph.
