we know that KUCN=105
CN=51
HMKU=96
HM=HMKU-MKU=96-78=18
we know that JN=JK+KN=82+105=187
JN=JH+HM+MKU+UC+CN
187=22+18+78+UC+51
UC=18.
This can be
solved by solving the slope of the line. First let y be the rating of the test
and x be the number of incorrect answers. Slope can be solved using the formula:
M = ( y2 –
y1 ) / ( x2 – x1)
M = ( 90 –
98) / ( 5 -1 )
M = -2
<span>So the model
has a negative slope</span>
the plus sign (+) means above seal level
so the sign should say 2100 feet above sea level
Hehehaheheeeh hheeeheehehe
In mathematics, the statement if a, then b, says that if a is true, then be is true. If you think about it, this makes sense too. That means that the answer is C., because of the definition of the statement.
