Answer:
It is stratified random sampling.
Step-by-step explanation:
Stratified random sampling is a method of sampling that involves the division of a population into smaller sub-groups known as <em>strata.</em>
The strata are formed based on members' shared attributes or characteristics, in this case their race.
Stratified random sampling is also called <em>proportional random sampling</em> or <em>quota random sampling</em>
Answer:
D. Each polygon has two pairs of congruent sides that are adjacent.
Answer: absolute value: -3
answer without absolute value: 3
Step-by-step explanation:
Since it has absolute value signs, you will take it out of it and since it is a - (-) it turns the 3 positive, however in absolute value form it is -3
It’s 3! 3x4 is 12 and 5 isn’t a factor of 12
Answer:
Table 1
Step-by-step explanation:
For a function to be linear, equal changes in x must correspond to equal changes in y.
In all tables, the x values increase by 1, so all changes in x in all 4 tables are 1.
If a function is linear, then all changes in y must be equal.
Table 1:
5 - 6 = -1
4 - 5 = -1
3 - 4 = -1
All changes in y are equal, so the first table is linear.
Table 2:
4 - 3 = 1
6 - 4 = 2
Two differences in y are different, so table 2 is not linear.
Table 3:
6 - 7 = -1
5 - 6 = -1
3 - 5 = -2
Not all differences in y are equal, so table 3 is not linear.
Table 4:
4 - 2 = 2
5 - 4 = 1
Not all differences in y are equal, so table 3 is not linear.
The only table that has equal differences in y corresponding to equal differences in x is Table 1, so only Table 1 shows a linear function.
