Answer:
a. No
b. Stratified Random Sampling was used
Step-by-step explanation:
a. No, I don't think the group was using a simple random sampling SRS ,because statistician students takes a survey of 200 samples and the sample was distributed into different categories , which is unlikely to happen in simple random sampling.
b. I think stratified random sampling was used because this type of sampling requires the population strata to be made.
In the question, the population is 200 and it is distributed into 4 strata which are :50 first-year students, 50 sophomores, 50 juniors, and 50 seniors.
Thus, the stratified random sampling was used
9(9+3) is the answer you are looking for
Answer:
(12, 3)
Step-by-step explanation:
write the equation:
if x = number of 2 point shots
and y = number of 3 point shots
2x + 3y = 33
write another equation with the total baskets
x + y = 15
plug them both into desmos and find the solution
(12, 3)
she made 12 2-point shots and 3 3-point shots
1. 40
2. 43
its just like subtracting when you add a negative number to a positive one. flip them around! makes it a lot easier.
