First you divide them all by 7 to see which are greater than 19
28/7=4
84/7=12
35/7=5
105/7=15
even if you add 1 to them they all are still less than 19
so select them all
hope this helps! :)
Answer:
it would be 1.09x10^4
Step-by-step explanation:
Answer:
square root
Step-by-step explanation: i think this is right but please tell me if it is wrong
Step-by-step explanation:
Solution,
No. of people who participated= 20
No. of people who didn't participated= 15
Total number of people= 20+15= 35
Now,
Percentage of people who didn't participated
=No. of people who didn't participated/Total number of people×100%
=15/35×100%
=42.86%
Again,
Percentage of people who participated
participated=No. of people who participated/Total number of people×100%
=20/35×100%
=57.14%

Answer:</h2>
A. It is a many-to-one function.
<h2>
Step-by-step explanation:</h2>
Hello! It will be a pleasure to help to figure out what's the correct answer to this problem. First of all, we have the following function:

When plotting this function, we get the red graph of the function shown below. So let's solve this as follows:
<h3>A. It is a many-to-one function.</h3>
True
A function is said to be many-to-one there are values of the dependent variable (y-values) that corresponds to more than one value of the independent variable (x-values). To test this, we need to use the Horizontal Line Test. So let's take the horizontal line
, and you can see from the first figure below that
is mapped onto
. so this is a many-to-one function.
<h3>B. It is a one-to-one function.</h3><h3>False</h3>
Since this is a many-to-one function, it can't be a one-to-one function.
<h3>C. It is not a function.</h3>
False
Indeed, this is a function
<h3>D. It fails the vertical line test.</h3>
False
It passes the vertical line test because any vertical line can intersect the graph of the function at most once. An example of this is shown in the second figure below.
