Isamu decided to use blocking to deal with an extraneous factor in his experiment. what will blocking do to the subject in his e
Olegator [25]

Answer:

b. divide them into groups based on similarities

Step-by-step explanation:

Blocking is a method in statistics used to reduce the effect of nuisance variables in an experiment. Nuisance variables are those factors that could result in variations during the experiment. During blocking, subjects with similar features are grouped in the same block, and treatment is then administered to each of these subjects. In order to form blocks, blocking factors are used.

Blocking factors can affect the results of an experiment but they are of no importance to the experimenter. An example of a blocking factor is age.  So, for Isamu who seeks to use blocking to deal with an extraneous factor in his experiment, blocking would enable him to divide his subjects into groups based on similarities.

Write a function number_of_pennies() that returns the total number of pennies given a number of dollars and (optionally) a numbe
seraphim [82]
Ok, first of all, it is important to understand that this function would depend on 2 variables; the number of dollars (x) and the number of pennies (y). Every dollar is equivalent to 100 pennies. So, if we are given x dollars, we have 100*x pennies. If we also have y pennies, we still get y pennies. We need to add these two to get the total amount of pennies. Thus, the correct function is:
f(x,y)=100*x+y
