Average speed = (distance final - distance initial)/(time final - time initial)
Average speed = (30-0)km /(100 -0)min = 3/10 km/min
3/10 km/min *60 min/1 h = 180/10 km/h= 18 km/h
That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.
If you had 2a+3a, then it would simplify to 5a
Similarly, 2b+3b = 5b
Or you could have 2ab+3ab = 5ab
The key is that the variable portions must match up to be able to add them.
The probability of a car crash is 56.75
Approx probability of car crash = 227/400 = 0.5675 i.e. 56.75%
This probability is high enough to be of concern to those in the 16-18 age bracket because the probability is not unlikely.
Probability is the department of mathematics concerning numerical descriptions of the way in all likelihood an occasion is to occur, or how probable it's miles that a proposition is actual. The probability of an occasion is more than a few between zero and 1, in which, kind of talking, 0 indicates impossibility of the occasion and 1 shows actuality.
The probability of an occasion can be calculated through chance system via simply dividing the favorable range of results by using the overall number of possible results.

Answer:
<h3 />
Step-by-step explanation:
That looks hard
The answer is z=20 because 25-6 is 19 and rounded that is 20
