What is the average of the given expenditures, which are $79.84, $278.99, $342.16, $466.25, $111.39, $502.47, and $98.12?
Correct — D. To calculate the average, we add up all the expenditures and divide the sum by the number of expenditures.<br/><br/>Sum of the given expenditures = $79.84 + $278.99 + $342.16 + $466.25 + $111.39 + $502.47 + $98.12 = $1879.22<br/><br/>Number of expenditures = 7<br/><br/>Average = Sum of expenditures / Number of expenditures = $1879.22 / 7 = $268.46<br/><br/>Therefore, the correct answer is B) $268.46.<br/><br/>Analysis of the wrong answer choices:<br/><br/>A) $278.99 - This is one of the given expenditures, so it is not the average.<br/><br/>C) $354.22 - This is not the correct average of the given expenditures.<br/><br/>D) $317.54 - This is not the correct average of the given expenditures.<br/><br/>The wrong answer choices (A, C, and D) do not accurately represent the average of the given expenditures. -

Which number is represented by the Roman numeral XXVII?
Correct — D. In Roman numerals, an “X” represents the number 10, a “V” represents 5, and “I” is representative of the number 1. In this problem we have 2 X’s, 1 V, and two II’s, which means we have two 10’s (20), one 5, and two 1’s (2). Written mathematically, 20 + 5 + 2 = 27. -

A store is pricing four lamps of different styles. Each one will be marked up differently. The cost of each lamp to the store and the desired markups are: Lamp 1 ($60) will be marked up 15% Lamp 2 ($80) will be marked up 20% Lamp 3 ($110) will be marked up 25% Lamp 4 ($150) will be marked up 30% The total price for all four lamps once they are marked up is which of the following?
Correct — A. The total sales price of the four lamps will be $497.50.<br/><br/>Lamp 1 ($60) will be marked up 15% ($9) = sales price of $69<br/><br/>Lamp 2 ($80) will be marked up 20% ($16) = sales price of $96<br/><br/>Lamp 3 ($110) will be marked up 25% ($27.50) = sales price of $137.50<br/><br/>Lamp 4 ($150) will be marked up 30% ($45) = sales price of $195<br/><br/>Total sales price is $69 + $96 + $137.50 + $195 = $497.50. -

The adductor muscle serves to <code>________</code>, whereas the abductor muscle serves to <code>________</code>.
Correct — C. <em>Adductor</em> muscles are those that move a body part <em>toward</em> the body’s midline. This can be remembered by learning that the prefix <em>ad</em>- means <em>to</em> or <em>toward</em>. Contrastingly, <em>abductor</em> muscles are those that move a body part <em>away from</em> the body’s midline. This can be remembered by learning that the prefix <em>ab</em>- means <em>away from</em>. -

Which of the following statements does NOT align with Darwin's theory of natural selection?
Correct — C. This is an illustration of artificial selection rather than natural selection.<br/><br/>Preferring only the most productive plants results in the promotion of traits preferred by the selectors, but these traits may not be the most advantageous to the species as a whole in its natural habitat.<br/><br/>Opting for solely the most productive plants often results in the sacrifice of other beneficial traits, such as disease resistance and drought tolerance. -

A genetic counsellor creates a pedigree analysis for a couple to determine the couple's chances of giving birth to a child with cystic fibrosis (CF), which is a recessive disorder. If the counsellor finds that neither the woman's grandmother nor her grandfather had the disorder but one of their children did, which of the following conclusions can the counsellor make?
Correct — C. The woman's grandparents had a child with CF, so both individuals must have been carriers of the CF gene (heterozygous) since the disease is recessive and neither had the disease. There is no indication that the woman has CF, and there is no way to conclude whether the woman is a carrier who will pass on the gene to a child based on the information provided. -

Just after providing the story, the author states: "These early observations provided the first clues of crosstalk between the brain and the gut."
