If x is the first number in the sequence, you can represent the next consecutive number using (x+1), the one after with (x+2), etc. We can set up an equation like this:
x + (x+1) + (x+2) + (x+3) = 130
This can be simplified to:
4x + 6 = 130
Now subtract 6 from each side:
4x = 124
Next we divide each side by 4:
x = 31
We have the first number in the sequence, but we need the THIRD number. Since we've already established that (x+2) would be the third number, we can just plug in x.
31 + 2 = 33
The third number in this sequence is 33.
Answer:
150
Step-by-step explanation:
The question is unclear. Do they want an angle that is under 180 (to your left) or over 180 (to your right)? I'm guessing that it is just under 180.
Each hour on a clock takes up 30 degrees. Each 5 minutes hand sweep out out 5/60 * 360 = 30 degrees as well. This angle looks like it is 5 minutes to seven if it was on a clock.
So the large angle from 12 oclock would sweep out 210 degrees and that would mean that the left angle would be 150. But the time is not quite 7 o,clock.
My guess would be 150. Remember, this is an estimate. You can't use a protractor on the question.

Answer: it is called genetic drift
Step-by-step explanation:
To explain this it is important to know the meanings of some concepts like allelles which is one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. So in other words the concept that the paragraph is referring is about the descendancy that can be traced by these alleles.
In other words, the paragrapgh states that some individuals when having more children leave more genetic load in subsequent generations and this subsequent load is illustratin in part what is called genetic drift which is many times a random effect on biological populations. Its effect is to remove genetic variation from a population of living organisms. In natural populations there are a number of forces acting. There are forces which add heritable variation to the population, such as mutation and recombination.
