Answer is: A. 0.50 [x + (x + 0.25x)], B. 0.50 (x + 1.25x), E.0.50 (2.25x)
You can conclude that X is smaller than Y. For example:
(2,5)
2 + 5 = 7
2 - 5 = -3
Hope this helped!
Answer:
a score of 105 is one standard deviation above the mean
the rule says that 68% of a normally distributed population lies within one standard deviation of the mean...half above the mean and half below
so 34% are within one standard deviation above the mean
this means that 16% are above that value
Step-by-step explanation:
Answer: D. 5 - x^4
Step-by-step explanation: We can see that the blue function is translated three units up, and inverted, so its leading coefficient is negative. The blue function can be rewritten as -x^4 + 3 to reflect these transformations. The only difference between the blue and the red function is that the red is two units higher, or five units total from the origin. Since they are the same shape, it will have a -x^4 in the formula, but since it is translated five units up its formula will be -x^4 + 5, which is also equal to 5 - x^4.
