Answer:
a. The degree of the function is odd, so the ends of the graph continue in opposite directions. Because the leading coefficient is positive, the left side of the graph continues down the coordinate plane and the right side continues upward.
Step-by-step explanation:
The given cubic polynomial function is
The degree of this function is odd because 3 is an odd number.
Therefore the ends of the graph, continue in opposite direction.
As x-values gets bigger and bigger negatively, the graph continues down on the Left.
As x-values gets bigger and bigger positively, the graph continues up on the right.
Therefore the correct option is A.
Answer:
UCL (X-bar) = X mean+ (A2 x R-bar)
LCL (X-bar) = X mean -(A2 x R-bar)
Center line = Mean
A2 for sample size of 10 = 0.308
X mean = 45.343019
R bar = Average of range = 0.0076382
UCL (X-bar) =45.343019+(0.308*0.0076382) = 45.3453715656 grams
LCL (X-bar) = 45.343019-(0.308*0.0076382) = 45.3406664344 grams
Center line = Mean = 45.343019
Answer: 4
Step-by-step explanation:
All you have to do is multiply each number 14 * 4 = 56 : 16 * 4 = 64 : and 7 * 4 = 28
