Janna is making a prediction of the frequency of a key that is 12 keys from middle c. which best describes her prediction? interpolation, because a key that is 12 keys from middle c is within the data set interpolation, because a key that is 12 keys from middle c is outside the data set extrapolation, because a key that is 12 keys from middle c is within the data set extrapolation, because a key that is 12 keys from middle c is outside the data set

Answers

The correct answer is:

Extrapolation, because a key that is 12 keys from middle c is outside the data set.

Explanation:

Interpolation is inserting an intermediate value into an existing series using estimation or calculations from nearby values. A key 12 keys from middle C is not in the data set involved, so this is not interpolation.

Extrapolation involves using a trend or pattern to estimate unknown values past the values we have. Since this key would be past our data set that we have, this would be extrapolation.
Among the choices the one that  best describes her prediction is "extrapolation, because a key that is 12 keys from middle C is outside the data set".

Which of the following intervals represents the set (1,4) u [2,6]?a. (1,6]
b. (4,6]
c. [2,4)
d. (2,6]

Please show work,

Thanks!

Answers

(1;\ 4)\ \cup\ [2;\ 6]=(1;\ 6]\n\nAnswer:A.
Set is a sum of two intervals :(1,4) u [2,6] 
In the first interval it is open on both sides so 1 and 4 don't belong to this interval, the second is closed so both 2 and 6 belong to interval and numbers between 2 and 6
We can write it as 1<x\leq 6
summing both sets we have one set: (1,6]
so
a) represent our set
b) also represent because all numbers between 4-6 and 6 are in our set
c)also represent, all numbers are in main set
d)also represent

If 2+xi=(x+1)+i, what is the value of xand can you please show me the breakdown?

Thanks!

Answers

2+xi=(x+1)+i\n\nxi-x=1+i-2\n\nx(i-1)=i-1\ \ \ \ /:(i-1)\n\nx=(i-1)/(i-1)\n\nx=1
2+xi=x+1+i\n xi-x=-1+i\n x(i-1)=-1+i\n x=(-1+i)/(i-1)=\nx =(i-1)/(i-1)\n x=1
