The only correct answer is C.) 9
✓16 = 4
5+4= 9
x = 9
Step-by-step explanation:
y+3=x
or 0=x-y-3... ans
3x+4y=16
or, 3x+4y-16=0 answer.......
The answer is 21 because if you subtract 17 from 17 and 38 you get 21. Z=21.
Answer:
C. Probability is 0.90, which is inconsistent with the Empirical Rule.
Step-by-step explanation:
We have been given that on average, the parts from a supplier have a mean of 97.5 inches and a standard deviation of 6.1 inches.
First of all, we will find z-score corresponding to 87.5 and 107.5 respectively as:










Now, we need to find the probability
.
Using property
, we will get:

From normal distribution table, we will get:



Since the probability is 0.90, which is inconsistent with the Empirical Rule, therefore, option C is the correct choice.
