Answer:
Step-by-step explanation:
162, 188, 197, 201, 266
a. add all number: 1014/ 5 = 202.8
b. 266-162 = 104
c. for each number subtract the mean and square the result.
1664.64+219.04+33.64+3.24+3994.24
= 5914.8/5 = 591.48
d. square root of variance
= 24.32
e. i don't know this one because i need the number of people in the family
126/7=18 (so that's 18 ounces per bag)
now subtract the 3 ounces that were added to each bag:
18-3=15
so the old almond bag weighed 15 ounces
You didn't supply a list. The so-called rigid transformations of translation, rotation and reflection create congruent triangles.
Generally it's dilation by a factor about a point is preserves similarity but not congruency. Any transformation which includes such scalings but is otherwise rigid also preserves similarity but not congruency.
