there is a proportional relationship between your distance from a thunderstorm and the amount of time that elapses between the time you see lightning and the time you hear thunder. if there are 9 seconds between ligtning and thunder, the storm is about 3 kilometers away. if you double the amount of time between lightning and thunder, do you think the distance in kilometers also doubles?

Answers


Yes, I think so.  In fact, I'm convinced of it.
If it is a directly proportional relationship, than yes, it doubles.



But this is not true in terms of the science of physics since sound dissipates over distance and is refracted through different mediums :3

Suppose P(A) = 0.9, P(B) = 0.3, and P(B|A) = 0.2. What is P(A|B) ?

Answers

By definition of conditional probability,

P(B\mid A)=(P(B\cap A))/(P(A))\implies P(B\cap A)=0.2\cdot0.9=0.18

Similarly,

P(A\mid B)=(P(A\cap B))/(P(B))=(0.18)/(0.3)=0.6

What is the simplest form of the fraction
4/10

Answers

Both the numerator and the denominator are divisible by 2.

(4/2)/(10/2) so the simplest form would then be 2/5

Your answer is: 2/5

The simplest form of the fraction 4/10 is 2/5.

To simplify the fraction 4/10, you need to find the greatest common factor (GCF) of the numerator (4) and the denominator (10) and then divide both by that factor.

Step 1: Find the GCF of 4 and 10.

Factors of 4: 1, 2, 4

Factors of 10: 1, 2, 5, 10

The GCF of 4 and 10 is 2.

Step 2: Divide both the numerator and denominator by the GCF (2).

4 ÷ 2 = 2

10 ÷ 2 = 5

So, the simplest form of the fraction 4/10 is 2/5.

In conclusion, the fraction 4/10 can be simplified to 2/5 by dividing both the numerator and denominator by their greatest common factor, which is 2. This simplified form represents the same portion of a whole but is expressed in its most reduced form.
