Answer:
Step-by-step explanation:
Two triangles are said to be congruent if all their corresponding sides and corresponding angles are equal to each other.
Given that L is the midpoint of KN an MP, hence:
KL = LN; and ML = LN
Also, ∠KLM = ∠PLN (vertical opposite angles are congruent to each other)
Since ∠KLM = ∠PLN, KL = LN; and ML = LN, we can hence say that triangle KLM and triangle LNP are congruent triangles using Side-angle-side (SAS) triangle congruency theorem.
The SAS theorem states that if two sides and one included angle of one triangle is equal to two sides and an included angle of another triangle, then both triangle are congruent
Answer:
r = 0.99
Very strong positive correlation between x and y
Step-by-step explanation:
Given is a data containing years and the corresponding heights
We have to find the correlation coefficient.
x y
1 2.1
2 3.2
3 6.8
4 7.3
5 11.2
6 12.6
7 13.4
8 15.9
r 0.988670694
Formula for r is
Thus we find that correlation coefficient is 0.988670694
Rounding off to two decimals r = 0.99
Very strong positive correlation between x and y
Move k to the other side to isolate d.
So we will get 3d = 8c - 8d - k
Now divide both sides by 3 to isolate d.
So d = 8/3c - 8/3d - k/3
Answer:
The range is the difference between the smallest and largest number within the group of numbers. so simply lists your numbers in the stem and leaf plot from smallest to largest and then find your largest number in the set and your smallest number in the set and subtract the two. Then there you have it ! The range of the stem and leaf plot
