Answer:
C
Step-by-step explanation:
a is wrong because residuals are solved using y and not x
b is wrong because a residual closer to 0 would be more accurate, but f is less accurate than g
c is right because residuals are solved using y and a more accurate residual would be closer to the real answer's y value
hope this helped ^_^

Answer:
<em>2(x) + 2(x + 3) = 90 </em>
Step-by-step explanation:
Width: x inch.
Length: (x + 3) inch.
P = 2 + 2
P = <em>2(x) + 2(x + 3) = 90</em>
Answer:
64 visitors (other 80%)

20% of visitors of 80 visitors is 16
So.. 80 - 16 = 64 visitors.
The other 80% of visitors being 64 visitors ordered fish.
Answer:
6 units
Step-by-step explanation:
Given: Points H and F lie on circle with center C. EG = 12, EC = 9 and ∠GEC = 90°.
To find: Length of GH.
Sol: EC = CH = 9 (Radius of the same circle are equal)
Now, GC = GH + CH
GC = GH + 9
Now In ΔEGC, using pythagoras theorem,
......(ΔEGC is a right triangle)
Now, Let GH = <em>x</em>
On rearranging,
So x = 6 and x = - 24
∵ x cannot be - 24 as it will not satisfy the property of right triangle.
Therefore, the length of line segment GH = 6 units. so, Option (D) is the correct answer.
