Answer:
c. 1.67 standard deviations above the mean
Step-by-step explanation:
The z-score measures how many standard deviations a score X is from the mean. It is given by the following formula:
In which 
is the mean and 
is the standard deviation.
A positive z-score means that X is above the mean, and a negative Z-score means that X i below the mean.
In this problem, we have that:
Tyler consumed 13 pounds of sugar last year How many standard deviations from the mean is that?
This is Z when X = 13. So
So this is 1.67 standard deviations above the mean.
C...to show this, interchange letters: x = (y+1)/(y-1)xy-x = y + 1xy - y) = x + 1y(x-1) = x+1y = (x+1)/(x-1) ⇐ this is f-1(x) and it's identical to f(x). Note: <span>the equal sign is missing in the definitions of the functions c. & d.</span>
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.
<h3>What is an
equation?</h3>
An equation is an expression used to show the relationship between two or more numbers and variables.
Let x represent the cost of white chocolate chip and y represent the cost of oatmeal dough, hence:
12x + 6y = 192 (1)
Also:
6x + 12y = 222 (2)
From both equations:
x = 9, y = 14
The cost of one package of white chocolate chip cookie is $9 while the cost of one package of oatmeal cookie dough is $14.

The converse of a logicalstatement is a s tatement formed by reversing the parts of the statement.
For example, the logical statement "A implies B" has a converse of "B implies A"
The linear pairs theorem states that "<span>if two angles form a linear pair, then they are supplementary".</span>
The converse of the linear pairs theorem is therefore, "if two angles are suplementary, then they form a linear pair".
