Let x be the first number each pair and y is the second of each
As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y
Last 4x =3*3*3*3y= 81y
So y = 3^x
Answer:
it is a convenience sample
Step-by-step explanation:
easy 214.7 because if it was rounded it would be 214.700 an this is way bigger than 214.275
B) y = -2x
when x = a
y = -2a
when x= 2a
y = -2(2a) = -4a
8:15 or 8 to 15 would be the ratio because you compare 8 quarters to 15 coins.
