Answer:
w=5
Step-by-step explanation:
using the distributive property to simplify the equation
-4(w)+1(-4)=-24 so
-4w-4=-24 (adding 4 to both sides)
-4w==20 (divide by -4)
w=5
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:
y = -6, perpendicular
Step-by-step explanation:
You can use the points to find the slope of the line:
Then, using point-slope form, choose one set of coordinates to use for y1 and x1:
Since the slope of the line is zero, it's a horizontal line. The y-axis is a vertical line, which means that the line is perpendicular to the y-axis.
