14x is the sum or 5x and 9x
To complete the square, you can add (and subtract) the square of half the x coefficient.
... y = x² -10x + 30
... y = (x² -10x +25) + (30 -25)
... y = (x -5)² +5
Answer: There is sufficient evidence to support the claim that the bags are under-filled.
Step-by-step explanation:
Since we have given that
Sample mean = 411
Standard deviation = 20
n = 9
So, the test statistic value is given by
At 0.025 level of significance,
critical value z = -2.306
since -2.306<-1.05
so, we will reject the null hypothesis.
Yes, there is sufficient evidence to support the claim that the bags are underfilled.
X-8/5=2/4
4(x-8)=5(2)
4x-32=10
4x=10+32
4x=42
x=42÷4
x=10.5
Answer:
C = (4,4)
It is (4,4) because it means that it is twice as large as the original coordinates.
