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>
Answer:
It is the answer closest to the right. The one with a straight line.
Step-by-step explanation:
Because it is a function if there is only one dot per line vertically. The others have either 2 or more dots per line vertically.
Answer:
scalene
Step-by-step explanation:
you can tell by the shape
Take the radius squared 10*10=100 then times that by pi which equals 314 then by 16 which is 5,024 then multiply that by 75 and get 376,800
Answer:
C = 21.78 and a= 8.88
Step-by-step explanation:
Here, sides b=7 and c=3
Also, Angle B=60
Angle B is between side c and a
It can be solve by cosine rule and sin rule
sin rule says,

cosine rule says,
