The set of all values for which the function is defined
A statistical question is one for which you don't expect to get a single answer. Instead, you expect to get a variety of different answers, and you are interested in the distribution and tendency of those answers. For example, "How tall are you?" is not a statistical question. But "How tall are the students in your school?" is a statistical question.
To solve this problem, we have to set up a proportion, letting x represent the unknown height of the tree.
5 feet/8 feet = x feet/ 32 feet
To solve this equation, we have to use cross products, or the multiplication of the numerator of one fraction by the denominator of the other fraction, and setting them equal to one another.
5(32) = (8)x
When simplified, as we multiply the numbers on both sides of the equations, we get the equation:
160=8x
20=x
Therefore, if a tree's shadow is 32 feet long, the height of the tree is a) 20 feet.
Answer:
A
Step-by-step explanation:
Since Angle XYZ is equal to Angle YZX,
XY=XZ
The two triangles are congruent.So,
VW=YZ
XY=UV
XZ=UW
Thus;
XY=UV
XZ=UW
XZ=XY=UV=UW
So the permieter is 5.7 + 5.7 + 3.7 = 15.1 cm
