Answer:
Step-by-step explanation:
"A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling. Mathematical models are used in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in the social sciences (such as economics, psychology, sociology, political science).
A model may help to explain a system and to study the effects of different components, and to make predictions about behavior."
Answer:
57.885
Step-by-step explanation:
For such calculations a probability calculator is very helpful. The one in the attachment shows the 87th percentile to be 57.885.
___
A table of the standard normal distribution will tell you the 87th percentile corresponds to a z-value of 1.12639. Then the X value is ...
X = Zσ +μ = 1.12639(7) +50 = 57.885
4: 25
l1=2
l2=5
surface area= 6*l^2
so for 1st =6*2^2
2nd= 6*5^2
ratio=6*2^2 /6*5^2
ratio= 4/25
or 4:25
Answer:
the selected answer/2
Step-by-step explanation:
not a function because the same y has 2 different x values
Answer:
500 cm³
Step-by-step explanation:
Using the given values in the given formula, we find the volume to be ...
The volume of the sphere is about 500 cubic centimeters.
_____
<em>Additional comment</em>
The actual value of pi would add about 4.72% to this figure, bringing the estimate to about 523.6 cm³.
