Answer:
156 ≤ 5 (Which is wrong)
Step-by-step explanation:
You start with:
16(6)+20(3) ≤ 5
96+60 ≤5
156 ≤5
Which is wrong.
Answer:
52
Step-by-step explanation:
Given that :
Mean (m) = 78
Standard deviation (s) = 13
Score that is 2 standard deviations below the mean
Using the relation :
Zscore = (x - m) / s
2 standard deviations below the mean means a Zscore of - 2
Hence,
-2 = (x - 78) / 13
Cross multiply
-2 * 13 = x - 78
-26 = x - 78
x = - 26 + 78
x = 52
Score which is 2 standard deviations below the mean is 52
5/6 is equivalent to 20/24
3/4 is equivalent to 18/24
so 5/6 is bigger than 3/4 by 2/24
Answer:
