Answer:
A.
Step-by-step explanation:
Z-scores are expressed in terms of standard deviations from their means. <span>The standard score is simply the score, minus the mean score, divided by the standard deviation. It is calculated as follows:
z = X- mean / standard deviation
z = 2.7 - 2.4 / 1.5
z = 0.2</span>
Answer:
The range would be all real numbers
Step-by-step explanation:
In order to find (wor)(x), we need to start with the w(x) equation and then input the r(x) equation for every x in the w(x) equation.
w(x) = x - 2
(wor)(x) = (2 - x^2) - 2
(wor)(x) = -x^2
Given this equation, we know that x can be all real numbers
Answer:
if the perimeter is 75 units and the side lengths are x + 10 and x + 5 it would probably be plus 60 to make it 75
