2. 
, 2. Given
3. 
, 3. refl. prop.
4. ∠ABC ≅ ∠ DCB, 4. Alt int. ∠s are ≅
5. ΔABC ≅ ΔDCB, 5. Angle Side Angle ASA rule of congruency
The conditions for two triangles to be congruent includes;
1. All sides equal or SSS rule
2. Side Angle Side or SAS rule
3. Angle Side Angle or ASA rule
4. Angle Angle Side or AAS rule
5. Right angle Hypotenuse Side or RHS also known as Hypotenuse Leg, HL rule
To solve this problem you must apply the proccedure shown below:
1. You must make a system of equations, as below:
2. Let's call:
x: the number of first class tickets bought.
y: the number of coach tickets bought.
3. Then, you have:
x+y=7 (First equation)
970x+370y=3790 (Second equation)
x=7-y
4. By substitution, you have:
970x+370y=3790
970(7-y)+370=3790
y=5
x=7-y
x=7-5
x=2
Therefore, the answer is:
- Number of first class tickets bought=2
- Number of coach tickets bought=5
Answer:
A1 = 18
A(n) = A (n-1) -2
Step-by-step explanation:
N represents the number in a sequence and the difference in the sequence is -2 since each time the number is listed in the sequence it is divide by 2.

Answer:
Generally an unbiased statistic is preferred over a biased statistic. This is because there is a long run tendency of the biased statistic to under/over estimate the true value of the population parameter. Unbiasedness does not guarantee that an estimator will be close to the population parameter.
