Answer: a). 1/8

Step-by-step explanation:

If the coin is fair, then the odds of getting heads or tails should be equal, 12.

Draw the graph of the line that is perpendicular to Y= 4X +1 and goes through the point (2, 3)
spayn [35]

Given:

\begin{gathered} y=4x+1 \\ \text{ point }(2,3) \end{gathered}

To find:

Draw a graph of a line that is perpendicular to the given line and passing through a given point.

Explanation:

As we know that relation between two slopes of perpendicular slopes of lines:

m_1.m_2=-1

Slope of given line y = 4x + 1 is:

m_2=4

So, the slope of line perpendicular to given line is:

m_2=-\frac{1}{4}

Also, so line equation that is perpendicular to given line is:

y=-\frac{1}{4}x+c...........(i)

Also, the required line is passing thorugh given point (2, 3), i.e.,

\begin{gathered} 3=-\frac{1}{4}(2)+c \\ c=3+\frac{1}{2} \\ c=\frac{7}{2} \end{gathered}

So, line equation that is perpendicular to given line is:

y=-\frac{1}{4}x+\frac{7}{2}

The required graph of line is:

Average student loan debt after a bachelors degree increases from 18,108 in 2004 to 28,522 2014. Find the absolute change
RideAnS [48]

Answer:

The absolute change is 10,414

Step-by-step explanation:

To get the absolute change, we simply use the mathematical formula below

Absolute change = New value - Original value

From the question, the new value is 18,108 while the original value is 28,522

So the absolute change will be;

28,522-18,108 = 10,414
