Answer:
D
Step-by-step explanation:
Firstly,you must divide (6,2) to (x¹y¹).After that,you must divide (10,3) to (x²y²).Then you must substract (y²-y¹,x²-x¹).It will be like this (3-2,10-6).So the correct answer is 1,4 (D).Hope you will understand!
Answer :
That’s it, the probability of getting tail on a single coin toss times the number of observations.
In this case, 1/2 * 72 = 36
However, there’s something called chance error. How much do you expect the result to differ from the expected value? It can be calculated as follows:
The Standard Deviation of this experiment is √(0.5)(0.5) =0.5
The Standard Error is √72 (0.5) ≈ 4.18330 round to the nearst tenth is 4
So, the expected value is 36, give or take 4.
And since the number of tails in a toss coin experiment is normally distributed, then you can expect the number of tails to be between -2 and +2 SEs from the expected value 95% of the time.
In other words, if you repeat this experiment a large number of times, you can expect to obtain between 27 and 43 tails 95% of the time.
Hope this helps
I don’t have time for a specific answer right now but basically it would be in the same spot except flipped so it’s on the right now.
180(n-2)
N is number of sides
Nonagon has 9 sides.
9-2=7
7x180=1260
1.If the slopes of each equation are the same, they are parallel. If the slopes are the opposite reciprocal of each other, they are perpendicular.
2. The equations are parallel, here’s my work:
