Given x < 5
The graph will have an open circle at 5 indicating that x is not equal to 5, which would be a closed circle.
The ray will move to the left since values less than 5 are to the left of 5
Answer:
Triangle- (height × base)/2
Rhombus-(First diagonal×Second diagonal)/2
Trapezoid- (First base+second base)/2×height
N-gon= (Side-2)*180
Answer:
Below.
Step-by-step explanation:
To find the number of students in each grade you multiply the marks by the frequency density. The number of students is given by the area under the rectangles.
So to find the number of students with grade U (< 160) it is:
120 * 0.2 + 40*0.5
= 24 + 20
= 44.
The number for Grade E
= (200 - 160) * 0.5
= 40 * 0.5
= 20.
The others can be found in the same way.
