Two multiplied by 1 is 2. Then, add all of the zeroes. There are 10.
Your answer is 20,000,000,000.
X-axis = A (-7,-3) B (-7,-10) C (-1,-3) first they changed to the x-axis which is this. Just so you know on the x-axis the x-axis stay and the y-axis changed which is this.
When they reflect again on the y-axis the verter of A' is
A' (7, 3) = answer
On the y-axis the y- axis doesnt change but the x-axis changed.
Hope this help!
Answer:
The correct answer is B. 2π
Step-by-step explanation:
A rational number is one that can be represented using a fraction and an irrational number cannot be represented using a fraction.
-√4 = -2, which is a rational number
2π is not a rational number (we cannot express pi as a fraction exactly even though there are some close approximations)
2.2121... is also a rational number because it can be expressed as a fraction (21/99, or 7/33 simplified)
√225 is 15, which is a rational number
Therefore, the only irrational option is option B. 2π, which is your answer.
Hope this helps!
Answer:
C. Stratified Sampling
Step-by-step explanation:
Stratified sampling is a sampling method in which the overall population is divided into a number of smaller sub groups.
These smaller sub-groups are called as strata.
These sub-groups are formed on the basis of similar characteristics and attributes shared by the population.
It is also known as proportional random sampling.
