Answer:
50 cm² and 56 cm²
Step-by-step explanation:
The area (A) is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )
(2)
A = × (8 + 2) × (5 + 5)
= 0.5 × 10 × 10
= 5 × 10
= 50 cm²
(3)
A = × (12 + 2) × (4 + 4)
= 0.5 × 14 × 8
= 7 × 8
= 56 cm²

Answer:
130
Step-by-step explanation:
Slope = (y2 - y1) / (x2 - x1)
Let’s plug in our numbers, solve m, and then reduce
3 - (-3) / 1 - 3
6 / -2
Reduce > - 6/2
-3
Your slope is 3
Answer: Cluster Sampling
Step-by-step explanation:
In cluster sampling, researcher divides the population into groups ,which are called clusters. Then random sample of clusters are chosen ,and researcher conduct study to collect data about the population.
Here each bus is considered a cluster ,because busses are selected at random ,this sampling would be an example of cluster type of sampling.
