Example 1 – Constructing a frequency distribution table
Divide the results (x) into intervals, and then count the number of results in each interval. ...
Make a table with separate columns for the interval numbers (the number of cars per household), the tallied results, and the frequency of results in each interval.
1st one is C and then the 2nd one is B
Hi
QPR = 74 (vertically opposite angles)according to angle sum property which means if we add all the angles of triangle we get 180 degrees
So,
PQR=180-(74+51)
180-125=55
So answer is 55 degrees
We can find the y-intercept by plugging the value of x is zero, and from the graph, we can see the end behavior of the graph.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function and y-intercepts are given in the picture.
First function:
y = 3ˣ
To find y-intercept plug x = 0
y = 1
or
y-intercept is (0, 1)
As the x increases the graph reaches the positive infinity.
Second function:

Plug x = 0
y = 2
The y-intercept is (0, 2)
Graph approches zero as x increases
Third function:

Plug x = 0
y = 1
y-intercept is (0, 1)
Graph approches zero as x increase.
For match please refer to the attched picture.
Thus, we can find the y-intercept by plugging the value of x is zero, and from the graph, we can see the end behavior of the graph.

Answer:
45
Step-by-step explanation:
The little square at the bottom of the triangle is a 90 degree angle so add 90+45=135 and if the whole triangle equals 180 so you would do 180-135=45
