X would be 4! Since there is a right angle the two sides making the right angle are even!
Answer:
y = -4/3x -2
Step-by-step explanation:
Slope intercept for is y = mx+b where m is the slope and b is the y intercept
4x+3y=-6
We need to solve for y
Subtract 4x from each side
4x-4x+3y=-4x-6
3y = -4x-6
Divide each side by 3
3y/3 = -4x/3 -6/3
y = -4/3x -2
The slope is 4/3 and the y intercept is -2
The slope of this line is 1/2.
In order to find the slope of any equation, you can take two points and use the slope formula. For ease, we'll use the two intercepts that you can see: (0, -3) and (6, 0). The formula for slope is below.
m = (y2 - y1)/(x2 - x1)
In this equation, m is the slope and (x1, y1) is the first ordered pair and (x2, y2) is the second. So we place those values in to solve for m.
m = (y2 - y1)/(x2 - x1)
m = (0 - -3)/(6 - 0)
m = 3/6
m = 1/2
And that is your slope.
The 95% confidence interval for a population mean has a margin of error (E) of 41
The confidence interval for a population mean is given by:
Confidence interval = μ ± E = (μ - E, μ + E)
Where μ is the mean and E is the margin of error.
Since the confidence interval is (428, 510), hence:
μ - E = 428 (1)
μ + E = 510 (2)
Subtracting equation 1 from equation 2:
2E = 82
E = 41
μ - E = 428
μ -41 = 428
μ = 469
Hence the margin of error (E) is 41
