Answer:

Cluster sampling technique

Step-by-step explanation:

The cluster sampling technique can be defined as dividing the population into clusters and from each cluster all individuals are interviewed.

We are selecting five statistics classes at random at college and then interviewing all the students from each five class and this situation leads to cluster sampling technique. Here the population all the classes of college is divided into five clusters that are five statistics classes and then all students are interviewed from each class.

Answer: Cluster sampling technique

Step-by-step explanation:

Cluster sampling is any sampling procedure that the statistics can be divided into a finite

number of distinct and identifiable units, the most of groups or clusters in the statistics will correctly represent the total students that are interviewed in the class.

1. Triangles ABC and MNP are not congruent.

2. Triangles ABC and EFG are not congruent

3. Triangles ABC and STU are congruent.

4. Triangles EFG and MNP are congruent.

5. Triangles EFG and STU are not congruent.

Express each fraction as a percent. Round your answer to the nearest whole number.
GREYUIT [131]

Answer:

60.8% which rounds to 61%

42.61% which rounds to 43%

29.14% which rounds to 29%

Step-by-step explanation:

So, there are two ways to do this, either perform the division as you see it, or make it so it is  some number over 100 instead of what it is.


For the first one if you just do the division, either with long division or with a calculator you get exactly .608.  The other two are not as nice, jsut a warning.  From here you multiply it by 100 to get the percent.  For instance with .5 (which is half) the corresponding percent is 50%, which is after you multiply .5 by 100).  if you need help with the division let me know and I can work you through one.


if we go with the second way we would want to make 125 into 100.  To do this we need to multiply it by something to get to 100.  Or in other words, 125x=100.  This winds up being .8, or 8/10  You could also see it as dividing 125 by 1.25 or 5/4, if you need help with this (or any part in particular really) let me know.  


Anyway, since one part of the fraction is being multiplied or divided, the other part does too, so you would take 76 and do the same.  Whichever number you use you get 60.8.  You don't have to  multiply this by 100 since it is already part of a fraction over 100.


Again, let me know if you need more help, I will leave the other two to you unless you need the help.

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.
frozen [14]

Note: Consider we need to find the vertices of the triangle A'B'C'

Given:

Triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C'.

Triangle A,B,C with vertices at A(-3, 6), B(2, 9), and C(1, 1).

To find:

The vertices of the triangle A'B'C'.

Solution:

If triangle ABC is rotated 90 degrees clockwise about the origin to create triangle A'B'C', then

(x,y)\to (y,-x)

Using this rule, we get

A(-3,6)\to A'(6,3)

B(2,9)\to B'(9,-2)

C(1,1)\to C'(1,-1)

Therefore, the vertices of A'B'C' are A'(6,3), B'(9,-2) and C'(1,-1).
