Xelga [282]3 years ago
8 0

Answer:

15y-2

Step-by-step explanation:

Please use parentheses if needed, this has me confused but without them, I solved it.

(-2y)(3)+3y-3y+7y(3)+1+2+5

-6y+3y+-3y+21y+1+2+-5

Combine like terms

(-6y+3y+-3+21y) + (1+2+-5)

15y + -2

Answer again: 15y - 2.

Verdich [7]

Answer:

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

n_{75} = 0.75* 9= 6.75\approx 7

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

x_{75} = 18

Step-by-step explanation:

For this case we have the following data:

16 17 11 21 15 14 17 18 19

The first step on this case is order the dataset on increasing way, and after do this we got:

11 14 15 16 17 17 18 19 21

We have a sample size of n =9

And in order to find the 75th percentile we need to find the position for this percentile with this formula:

n_{75} = 0.75* 9= 6.75\approx 7

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

x_{75} = 18
