The answer to the question :) 17/40=.425
By definition, a scatter plot is a diagram generally used to compare two setz of data. As you can see, in this exercise asked for the relationship between "Age (years)" at the x axis and "Lenght (in)" at the y axis. Therefore, to plot the data given in the problem, you should order the numbers in a table, as you can see in the figure attached. Then, you can plot the following points:
(3,13); (3,15); (2,10); (5,17); (4,17); (5,19); (7,23); (6,18); (8,21); (6,19)
You can see the completed scatter plot in the figure attached.
Answer:
Step-by-step explanation:
let a be the first term and r be common ratio.
![a_{3}=ar^2=-45\\a_{5}=ar^4=-405\\divide\\\frac{ar^4}{ar^2} =\frac{-405}{-45} =9\\r^2=9\\r=\pm3\\9a=-45\\a=-5\\a_{7}=ar^{7-1}=ar^6=ar^4 \times r^2=-405 \times 9=-3645](https://tex.z-dn.net/?f=a_%7B3%7D%3Dar%5E2%3D-45%5C%5Ca_%7B5%7D%3Dar%5E4%3D-405%5C%5Cdivide%5C%5C%5Cfrac%7Bar%5E4%7D%7Bar%5E2%7D%20%3D%5Cfrac%7B-405%7D%7B-45%7D%20%3D9%5C%5Cr%5E2%3D9%5C%5Cr%3D%5Cpm3%5C%5C9a%3D-45%5C%5Ca%3D-5%5C%5Ca_%7B7%7D%3Dar%5E%7B7-1%7D%3Dar%5E6%3Dar%5E4%20%5Ctimes%20r%5E2%3D-405%20%5Ctimes%209%3D-3645)
