Answer:
YES
Step-by-step explanation:
The criterion for formation of a triangle is that the sum of any 2 sides should be greater than or equal to the third side
So, we will test it for all 3 sides
7.4 + 12.5 ≥ 19.9
TRUE
12.5 + 19.9 ≥ 7.4
TRUE
7.4 + 19.9 ≥ 12.5
TRUE
Therefore, the segments with the sides: 7.4 , 12.5 and 19.9 do form a triangle
1/7 * 1/2 = 1/14
1/2 because there is a 50/50% chance its either heads or tails
Add 5 to 19 which is 24 then divide it by -6 and it’s x= -4
Answer:
Expected value: 3/7
Change landing on purple to -1.5
Step-by-step explanation:
Expected value
=3(1/7) + 1(2/7) + 0(2/7) - 1(2/7) = 3/7
Fair game: Expected value = 0
Change the value of 0 to -1.5
