For a regular tessellation, the shapes can be duplicated infinitely to fill a plane such that there is no gap. The only shapes that can form regular tessellations are equilateral traingle(all sides are equal. This means that it can be turned to any side and it would remain the same), square and regular hexagon. Looking at the given options, we have
Shape Tessellate?
Octagon No
Hexagon Yes
Pentagon No
Square Yes
Triangle No(unless it is specified that it is an equilateral triangle)
Answer:
No lol
Step-by-step explanation:
No
Answer:
n = 2m-4
Step-by-step explanation:
n+2/m-1=2
n+2=2(m-1)
n+2=2m-2
n=2m-2-2
n=2m-4
Answer:0.614
Step-by-step explanation:
Given
Probability he will miss flight if it rains=0.06
Probability he will miss flight it does not rain=0.01
Given the probability of rain=0.21
Therefore Probability that it will not rain=1-0.21=0.79
Probability that he will miss the flight 
P(actual raining and he missed the flight| he miss the flight)

If the line is parallel, it has the same slope. So now just find the y intercept and put it into slope-intercept form
