Answer:
7.5 cm²
Step-by-step explanation:
Dimensions of the large ∆:
![base (b) = 3cm, height (h) = 9cm](https://tex.z-dn.net/?f=%20base%20%28b%29%20%3D%203cm%2C%20height%20%28h%29%20%3D%209cm%20)
![Area = 0.5*b*h = 0.5*3*9 = 13.5 cm^2](https://tex.z-dn.net/?f=%20Area%20%3D%200.5%2Ab%2Ah%20%3D%200.5%2A3%2A9%20%3D%2013.5%20cm%5E2%20)
Dimensions of the small ∆:
![base (b) = 2cm, height (h) = 6cm](https://tex.z-dn.net/?f=%20base%20%28b%29%20%3D%202cm%2C%20height%20%28h%29%20%3D%206cm%20)
![Area = 0.5*b*h = 0.5*2*6 = 6 cm^2](https://tex.z-dn.net/?f=%20Area%20%3D%200.5%2Ab%2Ah%20%3D%200.5%2A2%2A6%20%3D%206%20cm%5E2%20)
Difference between the area of the large and the small ∆ = 13.5 - 6 = 7.5 cm²
Answer:
1. (1,10) 2. (2,-3) 3. (3,3)
Answer: Sequence B is more probable than A.
Step-by-step explanation:
This two sequences are not equally probable. Sequence B is more probable than A due to the equal chances of getting head (H) and a tail (T). The probability of getting a head is equal to the probability of getting a tail which is 4/8 i.e 0.5
The sequence A is less probable because the head(H) occur more than tail (T). The probability of head occurring is almost a sure event i.e 1 which is not feasible.
