In six seconds,a total of 3 waves crash onto the shore of the beach .
The distance between each wave crest on the water is 8 meters.
Wave length is the length between two wave crests that is the distance between two wave crests.
We know distance between each wave crest is 8 meters
Total of 3 wave crests, the distance between first and second wave crest is 8 meters
the distance between second and third wave crest is 8 meters
So wave length = 8+8 = 16 meters
Answer:
Step-by-step explanation:
#Given a significance level of 
and
the critical value is,
#the margin of error can then be calculated as:
Hence the margin of error is 3.4363
Answer:
Depending on the type of triangle you form, the interior angles will either decrease or increase.
Step-by-step explanation:
if you move the vertices to form an equilateral triangle then the interior angles will change to 60°, 60°, 60° because all interior angles of an equilateral triangle are the same and the sum of the interior angles of any triangle always add of to 180°
The partial variation is A
