Answer:
a) C
b) A
Step-by-step explanation:
The wingspan is the dependent variable while the bird height is the independent variable.
a) Since R2 is the dependent variable, it can be expressed by the independent variable. An R2 of 93% represents 93% of the variation in the wingspan which can be explained by using the birds height. This means that the appropriateness of the model should not be determined by R2 but by using a scatter plot.
b) The model predicts the value of wingspan using the value of bird height. We cannot say that the bird 10 inches tall has a wingspan if 17 inches instead, we say that the wingspan of the bird which is 10 inches tall is 17 inches.
It is therefore possible that the wing span is not exactly 17 inches
Let the starting position be A, and the ending position of the glide be B.
The triangle ABC shown in the figure, is a right triangle with side lengths 16m and 0.8 m.
The angle of the squirrel's path below the horizon is BAC.
Using right triangle trigonometry:
tan(ABC)=(opposite side)/(adjacent side)=0.8/16=0.05
to find m(ABC) we calculate arctan(0.05) which is 2.86°
Answer: 2.86°
Answer:
-7+26i
Step-by-step explanation:
Use FOIL
2•4+2(3i)+5i•4+5i(3i)
Simplify by combining like terms for your answer
8+6i+20i-15
-7+26i
