So 3 pounds cost 4$ and we need to figure out how much it is to purchase 1 pound of them.
All you need to do is divide the given cost by the given amount of pounds.
4 / 3 = 1.33333333333
<h3>So 1 pound will cost 1.33$</h3>
Hope this helps!
Answer:
a) 2 people
b) 20 people
Step-by-step explanation:
a) The social network contains four people networking with six other people, altogether there are ten people netwoking together.
So, if one person in one social network, network with five others in the network, but when it is paired, we have eight altogether in the first case.
When the other case are paired, it is discovered that, the remaining pair is left with two people networking with three other people.
b) Altogether, when it is paired in each case, the following summation provides the number of people that network with each other:
First case = 1 + 5 + 2 = 8
Second case = 5 + 4 + 3 = 12
Altogether it is 20 people
The confounding variable which is controlled by randomly assigning individuals to treatments is: C. the time of day participants drank the beverages.
<h3>What is a
confounding variable?</h3>
A confounding variable is also referred to as a confounder and it can be defined as a type of variable that has the ability to influence both the independent and dependent variables.
Also, a confounding variable is usually not accounted for by the researcher and as such it can cause a spurious association between the independent and dependent variables.
In this context, we can infer and logically deduce that the time of day at which participants drank the beverages is a confounding variable which is controlled by randomly assigning individuals to treatments.
