Assuming there 6-2 isn't in brackets, otherwise, it would be a tad more complex:
6 -2(x-4) = 22
6 -2x + 8 = 22
14 - 2x = 22
-2x = 8
-x = 4
x = -4
box number one: given
box number two: angle addition postulate
box number three: 51 degrees + 39 degrees = m DEF
box number four: 90 degrees = m DEF
box number five: DEF is a right angle
box number six: definition of a right triangle
just took the test and these are the correct answers, hope i helped :)
Answer:
12.25
Explanation
49/20 <em><u>(which is the same as (</u></em><em><u>4</u></em><em><u>9</u></em><em><u>÷</u></em><em><u>2</u></em><em><u>0</u></em><em><u>))</u></em><em><u> </u></em>=2.45
<em><u>Multiply</u></em><em><u> </u></em><em><u>2</u></em><em><u>.</u></em><em><u>4</u></em><em><u>5</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>amount</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>hours</u></em><em><u> </u></em><em><u>(</u></em><em><u>5</u></em><em><u>)</u></em><em><u> </u></em>

=12.25
In order for the mode to be 6, there must be more of them than any other number. In order for the mean to be 3.5, most of the distribution must lie at 3 or below to balance the large number of 6s. For the median to be 3, there must be as many scores at or above 3 as at or below 3. Thus, we choose to have most of the distribution with values 1, 2, 3 and only enough 6s to make that be the mode.
I think it’s .01% because 1225/120000=.010208
