(08.04 mc) christina bought a yoyo from a company that claims that, with each retraction, the string rolls up by 70% of the original length. she sets up a tape measure and throws the yoyo 3 times. her data are charted below. throw length of string (feet)
1 3
2 2.1
3 1.47

answers:

9.99
9.72
3.24
0.12

9.72

Step-by-step explanation: We can use the equation, a1 - a1(r^n)/1 - r

a1 = first term of sequence (3)

r = common ratio (0.70)

n = position of term in sequence (10)

1. 3 - 3(0.70)^10/1 - 0.70

2. 3 - 3(0.0282475)/0.30

3. 3 - 0.0847426/0.30

4. 2.91526/0.30

5. 9.72 is the sum of the lengths.

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

! < 3

have a splendid day < 3 : )

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
