Answer: (B) stratified random sampling.
Step-by-step explanation:
- A stratified random sampling technique is a sampling technique in which the researcher includes the participants from each group.
- He divides the entire population into groups and then he randomly selects participant from that groups of known as strata .
Here, Math department can send 6 people to a national convention and they would like to send 4 students out of 30 and 2 faculty members out of 6.
The department is considering both groups or strata of Students and faculty members as well.
And they selected 4 students randomly out of 30, and then 2 faculty members are randomly selected from the six.
Therefore , This is an example of stratified random sampling.
Hence, the correct option is (B) stratified random sampling.
1012x-7
multiplicas primero los paréntesis, en este caso seria 23(44), nos da 1012 y como 23 tenia "x" la agregamos 1012x y bajamos el -7 y nos da 1012x-7
X=4, you need to add 6 to both sides which then your equation would be x/4=1. You then multiply both sides by 4. Then you are left with x=1. Use symbolab!!!
(0,-2)(sry if I’m wrong :/)
A =
bh Multiply both sides by 2 to cancel out the fraction
2A = bh Divide both sides by h
= b Switch the sides to make it easier to read
b = <span>
