Answer/Step-by-step explanation:
Two figures can only be similar if their corresponding lengths are proportional to each other, that is the ratio of their corresponding sides are equal.
AB corresponds to HI.
AB = 2 units, HI = 1 units.
AB : HI = 2/1 = 2
The ratio of all the sides of ABCDEFG are equal to the corresponding sides of HIJKLMN, which is 2, EXCEPT for side FG which corresponds to MN.
FG = 1 units
MN = 1 units.
FG : MN = 1/1 = 1
This ratio is different from what we have for the ratio of the other corresponding sides of both figures.
Therefore, the figures are not similar.

Answer:
500 = 100%
20% = 60
Step-by-step explanation:
300 = 60%
50 = 10%
500 = 100%
100% = 300
10% = 30
20% = 60
Hope this helps!

No one of the mentioned
The interval is:
[ 1706.7 : 1917.3] to find 95.5 % of all values
Step-by-step explanation:
We deal with a Normal Distribution, : μ = 1812 and σ = 105.3
We know centered at mean value and at both sides at values σ/2 we will find 68.3 % of all values . In fact σ/2 to the left and σ/2 to the right means an interval μ + σ .
[μ + σ/2 : μ - σ/2 ] will lie 68.3 % of values
Following the same reasoning but now for a wider interval
[μ + σ : μ - σ ] We will find 95.5 % of all values in our case that interval is:
1812 + 105,3 = 1917.3
1812 - 105,3 = 1706.7
[ 1706.7 : 1917.3] will be the interval to find 95.5 % of all values
