Answer:
0.0015 or 0.15%
Step-by-step explanation:
Data
- mean age of sea turtles, μ: 80 years
- standard deviation, σ: 17.3 years
Z score is defined as:
Z = (x - μ)/σ
To find the probability of finding a sea turtle that is over the age of 131.9 years, we have to replace x = 131.9, to get:
Z = (131.9 - 80)/17.3 = 3
The 68 - 95 - 99.7 rules stands that (see figure attached):
P(Z > 3) = 0.0015
Answer: Below
Step-by-step explanation:
Volume is based off of the formula (base × height/depth), with base being (width × length).
We know the three dimensions of the taller box, so:
7.75 × 2 × 12 = 186
The smaller box is 20% shorter. 12 × 0.8 gives us the 0% height, which is 9.6.
7.75 × 2 × 9.6 = 148.8
Since the problem is asking for the difference of the two volumes we do:
186 - 146.8 = 39.2
Our answer is 39.2
Answer:
-7/20
Step-by-step explanation:
8/20+-15/20=-7/20
