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.
Angles in a triangle total 180°
180=128+5x+10+9x
180-128-10=5x+9x
42=14x
x=3
The answer is D. 877 + 228 + 34 + 104
D.
you do change in y divided by change in x
(5-1)/(1-0) = (4)/1=4
Answer:

Step-by-step explanation:

Take
& factorise it at first.

Now factorise the next set :
.

Now, multiply the two simplified results.
