15% of 30 = 4.5
30% of 45= 13.5
60% of 7= 4.2
23% of 20= 4.6
Answer:
x= 116°
y= 127°
Step-by-step explanation:
x... The angle subtended at the centre is twice the angle subtended at the cicumfernce by the same arch
y.... Angle in a cyclic quadrilateral add up to 180°
hence 180-53=127
What exactly are you asking?
The type of graph I would use for a set of categorical data with 25 people surveyed is bar graph.
<h3>Which types of graphs are good for categorical data?</h3>

- Pie charts
- Bar charts
Note that bar graph is one of the the most appropriate graphical form of displays for any categorical variables.

The true statements are:
2 - we can tell this by looking at the far right of the graph, as the slope is going downwards, therefore the leading coefficient must be negative
3 - this is a cubic, meaning its degree is 3
6 - by looking at the graph, we can see that there are 3 points where it cuts the x axis, hence 3 real zeros
7 - even multiplicity is where the curve "bounces off" the x axis and does not cross it. This curve have no zeros with even multiplicity
Hope this helped!
