Subtract -1 on both sides to get equation into standard form
2x^2 - 4x + 5.
The C value would be 5
The hypothesis testing for this problem is:
a. The hypothesis for this problem are:
Null: H0: μ=6
Alternative: Ha: μ≠6
b. Test
T-statistics = (6.08 - 6) / 0.44* √(121) = 2
c. P value = 0.047759
Since our p-value is smaller than the significant level of 0.05, we can say that we reject the null hypothesis.
Conclusion: there is enough evidence to say lathe is not in perfect adjustment.
To go from the original to number I you need to do a reflection across the y-axis. To go from I to II you need to do a 90 degree clockwise rotation about the origin.
Given point (2,8) and slope, we can use slope intercept form.
y-y1=m(x-x1)
y-8=-2(x-2)
y-8=-2x+4
y=-2x+12
Where, y=mx+b, b is the y intercept.
In this case, the intercept is 12.
Answer:
16.9%
Step-by-step explanation:
Given data
Initial populatation= 4164
Final population= 3460
Percent decrease= initial-final/initial*100
Percent decrease= 4164-3460/4164*100
Percent decrease= 704/4164*100
Percent decrease= 0.1690*100
Percent decrease= 16.9%
Hence the decrease is 16.9%
