HELPPP QUICK PLS I WOULD GIVE YOU THE BRAINIEST PLSSS HELPP MEEE BEFORE I HAVE A BREAKDOWN PLS What is the midpoint of a line se
Alisiya [41]

Answer:

(5.5, 12.5) OR (11/2, 25/2)

I would put in the decimal value as the answer, but of you like then you can add the fraction as an answer.

Step-by-step explanation:

We are given the endpoints (-4, 15) and (22, 3) to find the midpoint. In order to find the midpoint, we will use its formula.

Midpoint formula :- (x1 + x2 / 2, y1 + y2 / 2)

(x1 + x2 / 2, y1 + y2 / 2)

(<u>-4 + 15</u> / 2, <u>22 + 3</u> / 2)

(11 / 2, 25 / 2) ---> (5.5, 12.5) Midpoint

Hope I answered your question. Stay safe, happy, and healthy, thank you :) !!

Identify the sampling techniques​ used, and discuss potential sources of bias​ (if any). Explain. In​ 1965, researchers used ran
crimeas [40]

Answer:

For this case, the method used would be simple random sampling since random digit dialing assumes that all possible people in the population have the same probability of being chosen.

We may have a non-response bias, because if a selected person does not choose the phone, we have no answers to the questions and there is no data available.

We may also have under coverage bias because some people may not have a phone and in this case these people would be excluded from the study

Step-by-step explanation:

For this case is important to remember the different types of sampling methods

Simple random sampling is a method where we select a sample size n and each individual in the population are equally likely to be selected.

Stratified random sampling is a method on which we select samples from subgroups of the population usually called strata.

Convinience sampling is a method that use a random number so select the sample

Cluster sampling is a method that separates the population in natural subgroups with no intersection between them and some of the groups are selected for the sample.

For this case, the method used would be simple random sampling since random digit dialing assumes that all possible people in the population have the same probability of being chosen.

Sources of bias

We may have a non-response bias, because if a selected person does not choose the phone, we have no answers to the questions and there is no data available.

We may also have under coverage bias because some people may not have a phone and in this case these people would be excluded from the study
