Answer:
The statistical population consists of all college students. The sample is the answers given by the twenty college students.
Step-by-step explanation:
A population is an entire group from which a sample is pulled. In this problem, the population is all students in the college.
The sample is the portion of the population pulled. In this problem, this is the twenty college students.
Let's take a look at the triangles ABC and DCB
1. angles : B=C=90° because they are right triangles (AB perpendicular to BC and DC perpendicular to BC)
2. AC=BD (given)
3. BC is in common (the two triangles have it, you can say it like BC=BC)
So we proved that by SAS(side angle side), the triangles are congruent ABC= DCB
Since the triangles are congrueny, all their sides are equal so we can say that AB=DC
In order to simplify this expression, we need to multiply the numeric values together and the variables together.
So we have:
Therefore the correct option is the third one.
Answer:
14 miles remaining.
Step-by-step explanation:
2/9 of 18 is 4 -
2/9 x 18/1 = 36/9 = 4
Then you just subtract 4 from 18
18 - 4 = 14
Answer:
2
Step-by-step explanation:
opposite angles are the same
the shape opposite to 'z' is labelled with 2
which means that, that angle is 2 degrees
which also means that z would be 2 aswell.
