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.
Answer:
25 miles a day
Step-by-step explanation:
75 divided by 3 is 25
Answer:
77
Step-by-step explanation:
Plug in:
F(4) = (4)3 + 2(4)2 + 1
F(4) = 12 + (8)^2 + 1
F(4) = 12 + 64 + 1
F(4) = 77
(assuming 2x2 = 2x squared)
Answer:
1 / y^7
Step-by-step explanation:
Y^-9•y^-8•y^10
= y^10 / y^9•y^8
= y^10 / y^17
= 1 / y^7
