21-6=15
The range of the set is 15
Answer:
(-3, -4)
Step-by-step explanation:
y= -4
so you plus y in for the y=2x+2 equation where you get x=-3
Answer:
The confidence interval for the proportion of production lines that caused defects is (0.07, 0.09).
Step-by-step explanation:
A confidence interval for a population proportion is a function of the sample proportion and the margin of error.
The interval has two bounds, a lower bound and an upper bound.
The lower bound is the sample proportion subtracted by the margin of error.
The upper bound is the margin of error added to the sample proportion.
In this problem, we have that:
Sample proportion 0.08
Margin of error 0.01
0.08 - 0.01 = 0.07
0.08 + 0.01 = 0.09
The confidence interval for the proportion of production lines that caused defects is (0.07, 0.09).
Answer:
1/18
3/2
Step-by-step explanation:
18 = 18/1 if the reciprocal means to flip the denominator and the numerator then just witched them so it would be 1/18
2/3 would be 3/2
