Answer:
-2.5
Step-by-step explanation:
Here in this question, we are interested in calculating the z-score for a student that had a particular mark at the test
To calculate the z-score, we need to use a mathematical formula
Mathematically;
z-score = (x - mean)/SD
From the question;
x = 76
mean = 86
standard deviation SD = 4
Plugging these values in the equation, we have;
z-score = (76-86)/4 = -10/4 = -2.5
The answer to this question is D) 13.9 in.
Try using the Pythagorean theorem when solving to get the hypotenuse or other angles for a right triangle.
Answer:
The investment decreased by 16.5771% per share.
Step-by-step explanation:
Answer: ok so if you look at the difference it is 120 in 2 hours so to find 1 hour you divide it by 2, or split it in half and that means 60 and it is Decreasing so c is the answer. As for what y= it is y=-60x+480
60 cubic feet and you start out with 480
Step-by-step explanation:
120/2=60
decreasing
c
And y=-60x+480
