Answer:
-3/4
Step-by-step explanation:
First, pick two coordinates.
(0,2) and (4,-1)
Then do the rise over run or y/x.
The y is 3 and the x is 4. That is 3/4.
Since the line is going down, it will be negative.
The answer is -3/4.
Answer:
Stratified sampling
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
Population divided into groups, and random samples are drawn from the groups. This is a mark of stratified sampling.
Would it be 270? if you take 90 3 times. due to that there are 3 different durations.
Answer:
(-1,4) (-8,2) (-6,10)
Step-by-step explanation:
All you had to do is reflect it and figure out the new coordinates. There is you answer.... you welcome
Step-by-step explanation:
I have used substitution method here to find the value of x and y.
