To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps
- 1.}--diagonals bisect each other
- 2...and...3}.---two pairs of opposite sides are parallel and equal

- <em><u>none. I has no solutions (in all x, y and z) because in case x+y+z is 3 it can never be 4. So, it's imposible to find any (x,y,z) so that they satisfy both equations.</u></em>
- <em><u>To find the slope, convert the equation 21x - 3y + 18 = 0 to slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept). To do so, first subtract 18 and 21x from both sides to get -3y = -21x - 18. Then divide both sides by -3 to get y = 7x + 6. Therefore the slope is 7.</u></em>

Here they hav given the same value as 273.15 just to mislead you.
To find a temperature in Kevin's for a given temperature,you hav to add 273.15 to the given C° temperature.
So in this case write the equation
K = C° + 273.15
So to find the C° take the 273.15 to the other side of the eual sign.
Then the answer is
C°= K - 273.15
A line with undefined slope has an equation x=a.
So, for a line that passes through the point (x,y) = (-3,5) ,
has the equation x= - 3.
