Answer: 7/12!
Step-by-step explanation: 7/9 times 21/28 = 147/252. But you have to reduce it (simplify it) by dividing both the numerator and denominator by the greatest common factor and you get 7/12! Hope this helped.
Answer:
Stratified sampling
Step-by-step explanation:
The is a type of sampling in which the population of interest is divided into subpopulations and then each subpopulation is randomly sampled.
In this case study, instead of just doing a random sampling of all students, the research divided the population of all students into subpopulations which includes freshmen, sophomores, juniors and seniors and then she makes a random sampling of each of these subpopulations.
Slope = (11 + 5)/(4 - 2) = 16/2 = 8
y = mx + b
b = y - mx
b = 11 - (8)(4)
b = 11 - 32
b = -21
Equation: y = 8x - 21
Answer : y = 8x - 21
