Yes y=3.6 is a direct variation
Step-by-step explanation:
f(x) = x² − 6x + 9
f(½) = (½)² − 6(½) + 9
f(½) = ¼ − 3 + 9
f(½) = 6¼
The value is 6¼, or as an improper fraction, 25/4.
Answer:
y + 6 = 5/2(x+2)
Step-by-step explanation:
y plus 6 equals StartFraction 5 Over 2 EndFraction left-parenthesis x plus 2 right parenthesis.
Answer:
It must be integer because all the - number (negative number) include in integer.
Answer:
The critical t-value for such a test given an alpha level of 0.05 is 2.26
Step-by-step explanation:
Null hypothesis :
Alternate hypothesis :
Population mean =
Data : 10, 9, 6, 11, 13, 14, 9, 9, 9, and 10
Mean =
Mean =
Mean =10
Standard deviation :
Standard deviation :
Standard deviation s :2.144
Df = n-1 = 10-1 = 9
T critical =
T calculated > T critical
So, We failed to accept null hypothesis
Hence the critical t-value for such a test given an alpha level of 0.05 is 2.26
