22.2
Step-by-step explanation:
5x = 112
opposite angles of a parallelogram are equal
therefore x= 112/5
x= 22.2
Answer:
Perimeter = 2(l + b)
= 2(x + 5x³ + 4 - x²)
= 2x + 10x³ + 8 - 2x²
= 10x³ - 2x² + 2x + 8
Hence, ur answer is the first option.
Answer:
Simple random sampling
Step-by-step explanation:
In this example, the teacher takes a random 40-student sample from the whole population of students. The fact that the students are alphabetically order does not interfere in the sampling process since students are picked at random. Therefore, the teacher applied the simple random sampling method.
This method provides an unbiased representation of the population.
