Answer:
The correct option is A.
Step-by-step explanation:
From the given information it is clear that at x=25, the predicted value of y is 27.745 and the actually value is 29.
Predicted value = 27.745
Observed value = 29
The formula for residual is
Residual = Observed value - predicted value
The residual in this case is 1.255, therefore option A is correct.
Answer:
C
Step-by-step explanation:
using the sin ratio in the lower right triangle and the exact value
sin45° = , then
sin45° = =
=
[ y represents the hypotenuse ]
cross- multiplying gives
y = 7
------------------------------------------
using the sine ratio in the upper right triangle
sin45° = =
=
=
( cross- multiply )
x = 7 ×
= 7 × 2 = 14
