Answer: 95% confidence interval would be (26.01,29.39).
Step-by-step explanation:
Since we have given that
n = 50
Mean = 27.7
Standard deviation = 6.12
We need to construct 95% confidence interval for the population.
so, z = 1.96
So, it becomes,

Hence, 95% confidence interval would be (26.01,29.39).
Answer:
x2−3x+2=x2−2x−x+2
x(x−2)−1(x−2)=(x−2)(x−1)
Now
x2−4x+3=x2−3x−x+3
x(x−3)−1(x−3)=(x−3)(x−1)
Thus, the only common factor is (x-1)
Option A

Answer:
x: (3,0)
y: (0,-10)
Step-by-step explanation:
x intercept is where the line crosses the x axis
y intercept is where the line crosses the y axis
Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15
The ratios are not equivalent because when they are reduced, they do not equal the same thing.
