Emelina wrote the equation of a line in point-slope form as shown below. (y+4)=3(x+2) What is Emelina’s equation in slope-interc
Sergeeva-Olga [200]

Answer:

y=3x+2

Step-by-step explanation:

We are given equation as

(y+4)=3(x+2)

Since, we have to write equation in slope-intercept form

so, we can use slope-intercept formula

y=mx+b

where m is a slope

b is y-intercept

so, we can write our equation in this form

(y+4)=3(x+2)

Distribute 3

y+4=3\times x+3\times 2

y+4=3x+6

Subtract both sides by 4

y+4-4=3x+6-4

y+4-4=3x+6-4

y=3x+2

So, slope-intercept form of equation is

y=3x+2

Identify the type of sampling used. In a recent online​ survey, participants were asked to answer​ "yes" or​ "no" to the questio
Anastaziya [24]

Answer:

The sampling technique used is convenience sampling.

Step-by-step explanation:

Convenience sampling technique is a method of non-probability sampling that is done using the most easiest sample or the most convenient sample.

For instance, sampling the people of our neighborhood, or school or company, etc.

This type of sampling is known as non-probability sampling because each individual\participant does not have a specific probability of selection. Whereas in case of probability sampling each participant has an equal probability of being selected.

Survey that are conducted through online portals or online survey use samples that are quite easy to collect. The sample collected through online surveys is convenience sample.

The survey conducted to determine how many people were in favor of stricter gun​ control uses a convenience sampling technique. As it uses the most easy source to collect the sample.

Thus, the sampling technique used is convenience sampling.
