Answer:
Step-by-step explanation:
Given the following scores 3, 7 and 2, we are to find the expression Σ2X-2 and Σ(X-1)²
The value of X's are 3, 7 and 2. Substituting the values we will have;
Σ2X-2 = [2(3)+2(7)+2(2)] - 2
Σ2X-2 = (6+14+4) - 2
Σ2X-2 = 24-2
Σ2X-2 = 22
For Σ(X-1)²
Σ(X-1)² = (3-1)²+ (7-1)² + (2-1)²
Σ(X-1)² = 2²+6²+1²
Σ(X-1)² = 4+ 36+1
Σ(X-1)² = 41
It depends on what contract you are signing if you are having doubts then yes but not then no!
If the blue piece is half of the length of green, which is 12, then the blue piece would be 6cm long. 12 + 6 would represent the total length of both pieces, which is 18.
Answer:
y = 2x - 1
Step-by-step explanation:
1(2) - 1 = 1
2(2) - 1 = 3
3(2) - 1 = 5
4(2) - 1 = 7
