You are trying to estimate the percent of land that each Canadian province takes up based on the numbers you are already given and then taking the population of one of the provinces and dividing it by the total population to find the fraction of the Canadian population in that province.
The answer for #2 is B it might be wrong
Given:
The set of ordered pairs in the options.
To find:
The set of ordered pairs which does not represent a function.
Solution:
A set of ordered pairs represents a function if their exist a unique y-value for each x-value.
In option 3, the given set of ordered pair is:
{(−3,−3),(4,1),(−3,3),(2,2)}
Here, we have to y-values -3 and 3 for x=-3. It means the y-value is not unique for x=-3. So, this set of ordered pairs is not a function.
In option 1, 2 and 4, all the x-coordinates are different. It means their exist a unique y-value for each x-value. So, the set of ordered pairs in options 1, 2 and 4 represent a function.
Therefore, the correct opting is 3.
Answer:
length is 7 inches and the width is 5 inches
Step-by-step explanation:
Hello, I think I can help you with this
the area of a rectangle is given by:
Step 1
According to the question data,the length is two inches longer than its width.which means that you can take the width and add 2 inches to obtain the length, in mathematical terms
(equation 2)Width + 2 inches = length
Step 2
Now, put equation 2 into equation 1
Step 3
replace and solve for w
Let
A=35
so, the width is 5 inches,
replacing this value in equation 2
Width + 2 inches = length
5 in +2 in =length
7 in = length
so , the length is 7 inches
Have a good day.
