Answer:

a) The dependent variable is defined as the variable that is being tested. The dependent variable here is the percentage of children who collected extra candy.

b) The data does not support the hypothesis 1 of the psychologist which states that the children would take more candy when they were alone. In the graph, percentage of children that took extra candy was higher when they were in group than when they were alone.

The data supports the hypothesis 2, which states that the children would take more candy when they were masked. From the graph, the percentage of children who took extra candy was higher when they were masked than when when they were unmasked.

c) The psychologist cannot generalize her findings to all children because she didn't use a random sampling procedure and she used children only from her neighborhood which doesn't represent the general population of children.

d) This study is not a naturalistic behaviour because the psychologist is dealing with subjects. She may also choose to manipulate the variables. Therefore we cannot call this study a naturalistic behaviour.

e) Modeling: This may play a role in the children's behaviour because the children may try to imitate what others did. The children may take extra candy because they saw others collecting extra candy.

Deindividuation: Here, the children's behaviour may be influenced by a feeling of anonymity. The children may take extra candy because they feel anonymous. Deinvuduated children feel anonymous due a feeling of loss of identity.

This explains why the percentage of chidren who took extra candy when in group was higher than that of the children who were alone.

Solve the following systems of 3-variable linear equations.

Zina [86]

Answer:

x = 9/25, y = 7/25, z = 4/25

Explanation:

step 1: solve for y in first equation to use substitution

y = -2x + 1

step 2: insert into second equation to eliminate y variable and work with two variables

3(-2x+1) + z = 1 (now distribute)

-6x + 3 + z = 1 (bring over the -3)

-6x + z = -2

step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z

-6x + z = -2 (multiply by 4)

4(-6x + z = -2)

-24x + 4z = -8

x + 4z = 1 (brought down third equation)

-25x = -9

x = 9/25

then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25

Which model describes how data is written to a blockchain?

nasty-shy [4]

The model that describes how data is written to a blockchain is the: append-only data structure.

<h3>What is an Append-only Data Structure?</h3>

Append-only is computer data storage property whereby new data can be added to a blockchain, like an additional block, in a time-ordered sequential order in such a way that the data added cannot be easily altered as al data are permanently stored across all nodes.

The append-only data structure makes data stored almost immutable. This is the model in which the blockchain technology is built on.

Therefore, the model that describes how data is written to a blockchain is the: append-only data structure.
