Answer:
y = 3x + 6
Step-by-step explanation:
The domain is you x values. You need to substitute the x values into both functions to see which one produces the plots on the graph.
<h3>y = 2x + 4</h3>
when x = -3, y = 2(-3) + 4 = -6 + 4 = -2
when x = -2, y = 2(-2) + 4 = = -4 + 4 = 0
when x = -1, y = 2(-1) + 4 = = -2 + 4 = 2
when x = -0, y = 2(0) + 4 = 0 + 4 = 4
<h3>y = 3x + 6</h3>
when x = -3, y = 3(-3) + 6 = -9 + 6 = -3
when x = -2, y = 3(-2) + 6 = = -6 + 6 = 0
when x = -1, y = 3(-1) + 6 = = -3 + 6 = 3
when x = -0, y = 3(0) + 6 = 0 + 6 = 6
The points on the graph are (-3, -3), (-2, 0), (-1, 3) and (0, 6)
This is same as the results from the function y = 3x + 6
Answer:
Systolic variation coefficient (CVS) = 0.1446 = 14.46%
Diastolic variation coefficient (CVD) = 0.1789 = 17.89%
The variation, with respect to the mean, of the systolic pressure sample is slightly less than the variation of the Diastolic pressures.
Step-by-step explanation:
Systolic Mean (MS) = 127.8
Diastolic Mean (MD) = 73.5
Standard Deviation Systolic (sdS) = 18,486
Standard Deviation Diastolic (sdD) = 13.1508
The coefficient of variation is defined by:
Systolic variation coefficient (CVS) = sdS / MS = 18.486 / 127.8 = 0.1446 = 14.46%
Diastolic variation coefficient (CVD) = sdD / MD = 13.1508 / 73.5 = 0.1789 = 17.89%
Then, it can be concluded that the variation, with respect to the mean, of the systolic pressure sample is slightly less than the variation of the Diastolic pressures.
Answer:

Step-by-step explanation:
If you divide number 1 by number 3, you will notice that number 3 will constantly repeat at the decimal part.
So, the answer is
.
Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450
