Determine the x- and y-intercepts of the graph of y=1/4x−2 .
KATRIN_1 [288]
To find the x-intercept, put in 0 for the y.

0=1/4x-2
2=1/4x
8=x

The x-intercept is 8. The point is (8, 0).

To find the y-intercept, put in 0 for the x.

y=1/4(0)-2
y=0-2
y=-2

The y-intercept is -2. The point is (0, -2).

To graph, find the points on a coordinate plane and draw a straight line through them.

Hope this helps!

There are four red ,four blue, and two green marbles in a bag .if one marble is chosen at random from the bag what is the probab
mina [271]

Answer:

There is a 20% probablity that the marble will be green :)

Step-by-step explanation:

  • There are a total of 10 marbles in the bag. 4 red+4 blue+ 2green=10
  • There are two green marbles out of the 10 marbles.  2/10
  • 2 divided by 10 is .20 or 20%
  • Therefore, there is a 20% probability that the marble will be green.

dentify which type of sampling is​ used: random,​ systematic, convenience,​ stratified, or cluster. To determine customer opinio
Rudik [331]

Answer:

The type of sampling used is the Cluster sampling technique.

Step-by-step explanation:

- Random Sampling

In random sampling, each passenger would have an equal chance of being surveyed. If this particular scenario wanted to use random sampling, they would have used computer generated random passenger numbers and surveyed them, not just passengers all on the same bus picked randomly.

- Systematic sampling is easier than random sampling. In systematic sampling, a particular number, n, is counted repeatedly and each of the nth passengers is picked to be sampled.

- Convenience Sampling

This is the worst sampling technique. It is also the easiest. In Convenience sampling, the surveyor just surveys the first set of passengers that they find.

- Stratified Sampling

Stratified sampling divides the population into groups called strata. A sample is taken from each of these strata using either random, systematic, or convenience sampling.

- Cluster sampling

Cluster Sampling divides the population into groups which are called clusters or blocks (the different buses). The clusters are selected randomly, and every element in the selected clusters is surveyed (each passenger on the selected buses, is surveyed!). Evidently the answer to the question!
