Answer:
y = -2/3x
Step-by-step explanation:
To write in y=mx+b form, you need the y-intercept (b) and the slope (m).
The y-intercept is the point the line crosses the y-axis. This line crosses the y-axis of (0, 0). This makes the y-intercept equal to 0.
The slope is the rise of the line over the run of the line. Pick two points from the line. It doesn't matter which ones, you will get the right answer regardless.
I picked (0, 0) and (-3, 2). Subtract the x-values from each other, and subtract the y-values from each other.
-3 - 0 = -3 (x)
2 - 0 = 2 (y)
Divide the y by the x to find the slope.
2/-3 = -2/3
Plug in the slope and y-intercept into the equation.
y = mx + b
y = -2/3x + 0
y = -2/3x
Answer:
27
Step-by-step explanation:
Given that :
Dimension of poster board = 1 yd by 1 yd
Dimension of each poster sign = 1/3 yd by 1/9 yd
Number of poster signs that can be cut :
Area of poster sign = 1/3 * 1/9 = 1/27 yard²
Area of poster board = 1 yard²
Number of poster signs that can be cut :
Area of poster board / area of poster sign
1 yard² ÷ (1/27) yard²
1 ÷ 1/27
1 * 27/1
= 27 poster signs

Answer:
Below.
Step-by-step explanation:
f(x) = 2(x + 2) - 3 when x ≥ -2
f(x) = -2(x + 2) - 3 when x < -2
Answer:
24.6 < μ < 27.2
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 25.9 - 1.3 = 24.6 pounds.
The upper end of the interval is the sample mean added to M. So it is 25.9 + 1.3 = 27.2 pounds.
So the correct answer is:
24.6 < μ < 27.2
