Everyone would be confused because they wouldnt know how to add. if there wasnt money then there with be no objects/food/toys/ect. unless its all free. If it all free then everyone would go crazy because they wouldnt have to calculate how much the item cost.

It would be like the Barter System all over again. People would kill other people over chickens, cows, and pigs.

A Biology student who created a regression model to use a bird's height when perched for predicting its wingspan made these two
VLD [36.1K]

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

A squirrel in a long glide typically covers a horizontal distance of 16 m while losing 8.0 m in altitude. during this glide, wha
iragen [17]
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°
