Answer:
(a) LM=12 units, LN=35 units, MN=37 units
(b)8 84 units
(c) 210 square units
Step-by-step explanation:
(a)
Since points L and M have same x coordinates, it means they are in the same plane. Also, since the Y coordinates of L and N are same, they also lie in the same plane
Length
Length
Length
Alternatively, since this is a right angle triangle, length MN is found using Pythagoras theorem where
Therefore, the lengths LM=12 units, LN=35 units and MN=37 units
(b)
Perimeter is the distance all round the figure
P=LM+LN+MN=12 units+35 units+37 units=84 units
(c)
Area of a triangle is given by 0.5bh where b is base and h is height, in this case, b is LN=35 units and h=LM which is 12 units
Therefore, A=0.5*12*35= 210 square units
Answer: A
Step-by-step explanation:
The shape in the diagram is a square, a square is a shape with all sides being equal. To find out the length of all the sides, just count how many units make up one side since they're the same.
Answer:
1st attachment x=25,
2nd attachment x=107, x=-26
Step-by-step explanation:
a) Negative correlation
Negative correlation corresponds to points that move down as you go from left to right on the scatter plot.
b) Positive correlation
Positive correlation corresponds to points that move up as you go from left to right on the scatter plot.
c) No correlation
Scattered points on the scatter plot make no relationship.
