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

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
