Answer:

-4/3

Step-by-step explanation:

let (13,-4) be (x1,y1) respectively

(1,12) be (x2,y2) respectively

From,

slope=(y2 -y1)/(x2-x1)

=(12+4) /(1-3)

=16/-12

=-4/3

Tristan records the number of customers who visit the store each hour on a Saturday. His data representing the first seven hours

Alona [7]

Answer:

Option C is correct.

Step-by-step explanation:

We have been given total 8 data

Data is : 12,15,18,20,23,23,28

Here, n=7

Median is $\frac{n+1}{2}=\frac{7+1}{2}=4th term$

Median is 20.

When one data is added n=8

The median of even number of data is

$median=\frac{\frac{n}{2}\text{th and}\frac{n}{2}+1\text{th}}{2}$

Median is $\frac{8}{2}\text{th and}\frac{8}{2}+1th$

Median is $4\text{th and}5th$

4th terms is 20

5th terms is 23

Since, median should not be change hence,

Median will be 20.

Therefore, option C is correct.

Which choice represents the expanded form of the expression (x- 2)3

Murljashka [212]

Answer:

(x−2)^3=x^3−6x^2+12x-8

Step-by-step explanation:

if you are talking about the binomial (x−2)^3 you must expand then simplify. (x-2)3 you would just remove the parenthesizes and multiply -2 with 3 to get x-6 but I think you meant (x-2)^3

There is 15 bars in each case.

Subtract 8 from 143 and you get 135.

Divide 135 by 9 and you get 15 :)
