A Data Scientist of a Fortune 500 banking firm is looking at the relationships between various age groups of adults and types of investments portfolios. He is looking at a Chi Square distribution in his statistical software. What is the probability that x is larger than 12 when df = 19?
Answers
Answer:
The probability that x is larger than 12 when df = 19 = 0.100
Step-by-step explanation:
We are supposed to find the probability value at x>12 at degree of freedom equals to 19.
P(x>12)
By looking at the chi square table we can see, at df = 19 and x>12, P(x>12) is equal to 0.100
because at df = 19, the least x values is 27.2036 for which (Px=27.2036) or (Px>12) = 0.100

Reduce the ratio to its lowest form. 72:8
Answers
Answer:
9:1
Step-by-step explanation:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 72 and 8 is 8
Divide both terms by the GCF, 8:
72 ÷ 8 = 9
8 ÷ 8 = 1
The ratio 72 : 8 can be reduced to lowest terms by dividing both terms by the GCF = 8 :
72 : 8 = 9 : 1
Therefore:
72 : 8 = 9 : 1

the equations are in y = a(x-h)²+k format.
So, that means that since the vtx is (3, 1), the answers could only be c or d
The difference between the two is one parabola is reflected (negative) and the other is facing up. Since (1, 9) is above the vtx, only D is the one that passes through (1, 9) because it is the only one facing upward to touch that point.
