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
I have the same problem. if i find the answer i will give it to you
She 56/92 6-5=1 and 567-1=566
Answer:
Coefficient
Explaination:
I just know
Answer: 36.6
Step-by-step explanation: 2x+1+3x-4=180
add 2 & 3 to get 5x
subtract 1 from 1 & 180
so u would have 5x-4=179
+4 to 179
then 5x=183
divide by 5
x=36.6
hope it helps
