Answer: I not super sure, but I think you are supposed to put the equations on each side of the table. Your end result should be 2x to the second -5x-3.
Step-by-step explanation:
The answer is 1,000 4 or below you round down and 5 or higher you round up
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
Answer:
The Answer is 12
Step-by-step explanation:
Use Pythagorean theorem. AB=8 and BO=5 We still need to find AO
AO=AB+BO
8+5
AO=13
Now solve for AC
AC^2 + OC^2= AO^2
AC^2+5^2=13^2
AC^2+ 25=169
AC^2=144
AC= 12
