Answer:
D. 1.25
Step-by-step explanation:
The values of the correlation coefficient must be between -1 and 1 (they can include -1 and 1)
The only value outside that range is 1.25
1.25 is not a possible correlation coefficient
Answer: A transformation will <u><em>Sometimes</em></u> have a number
Step-by-step explanation:
The x value is greater than 6.4, and the y value is less than 1.8. (6 2/5,9/5)
Answer:
Domain: (-∞, ∞)
Range: [0, ∞)
Step-by-step explanation:
The domain represents what x can be. In this scenario, we do not have x as a denominator, and there is nothing limiting x, so its domain is (-∞, ∞)
The range represents what f(x) can be, Because |x-4| is in absolute value, the lowest |x-4| can be is 0, and as a result, the lowest value of 2|x-4| is 2*0=0. The maximum value of f(x) is ∞ as an absolute value does not limit the maximum, making the range [0, ∞)
