Answer: In math, especially when learning algebra and geometry, you are more likely to a lot of deductive reasoning. That is the process of using theorems, properties of numbers and other recognized rules and procedures to solve equations, to prove geometrical constructions, congruence of angles, etc. Deductive reasoning is the foundation of most of that kind of math, so it is more important when learning and applying the principles and theorems.

Inductive reasoning involves taking specific observations and known facts and using them to make predictions and generalizations. You are more likely to use inductive reasoning when working with statistics and probability.

So both are important at some point, but it may be more important to learn deductive reasoning at first.

Find two numbers whose difference is 176 and whose product is a minimum.
Zanzabum
Let the two required numbers be x and y, then x - y = 176, thus y = x - 176.

Let the product of the two numbers be represented by

P = xy x(x - 176) = x^2 - 176x

For the product to be minimum, \frac{dP}{dx} =0

\frac{dP}{dx} =2x - 176=0 \\  \\ \Rightarrow2x=176 \\  \\ \Rightarrow x=88

Thus, y = 88 - 176 = -88

Therefore, the two numbers are 88 and -88.

"x is an exponential random variable with mean equal to 100. what is the probability that x equals 90?"
Svetradugi [14.3K]

Since mean is 100 so Λ=1/100,

But since exponential distribution is continuous distribution so probability at a particular points  

Is zero. That probability  

That X is equal to 90 degree is 0.
