Hey there!
It can be both. It's a multiple of 8 because 8 times 5 is 40, but it's also a factor of 120 because 80 times 3 is 120.
Hope this helps!
Apparently the first term is zero, and every
subsequent term is equal to the one before it.
In step 3, when you combine the two terms, square them, and square root them, the squaring and square rooting messes everything up. Lets see what the right side is equal to throughout.
Now, since the
isn't going to change value throughout the whole problem, lets simply look at the other two numbers on that side.
In this step, the process of squaring and square rooting takes the number from -0.5 and turns it into 0.5. Since square roots are either positive or negative, this proof squares and square roots the initial number, allowing the value to be changed from the value we started with. Thus, instead of picking the -0.5, which makes the statement true, the proof uses the number 1 larger, 0.5. This is a very sneakily hidden way to increase the value of the number by one.
This is actually one of the smartest and the second hardest false proofs I have ever attempted to disprove. Only one has been harder to solve, and I am yet to solve it. I enjoyed the challenge!
Hope this was the answer you were looking for!
Answer:
0.78
Step-by-step explanation:
We have the next probability distribution:
X P(X)
0 0.2
1 0.3
2 0.5
As we can see when we add all the probabilites the result is 1. Now calculating the mean we have:
The standard deviation is:
Then using the data that we have:
Then the standard deviation is 0.78
Answer:
Chart 2.
Step-by-step explanation:
In the figure Dan has constructed an angle at point Q.He wants to cinstruct an angle ar point R which is congruent to angle made at point Q.To construct the angle at point R Dan needs to draw an arc at point R .He will put the compass on point R and draw an arc .This is shown in the figure 2.
The figure is added below.
