The fastest way to find the missing endpoint is to determine from the known endpoint to the midpoint and then performing the same transformation on the midpoint.

I'm going to try to let you answer this yourself so you can learn for yourself ok. :3

Making and Interpreting Correlations: Mastery Test

garri49 [273]

Answer:

Graph D > Graph A > Graph C > Graph B

Step-by-step explanation:

The closer the data points are to each other along the line of best fit, the greater the value of their correlation coefficient, and vice versa.

Therefore, the graphs can be arranged in descending other (from the highest to the lowest) based on the values of their correlation coefficients as follows:

Graph D > Graph A > Graph C > Graph B

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule. A(n)=-6+(n-1)(1/5) A)-6,-5 1/5,

scoundrel [369]

Step-by-step explanation:

An arithmetic sequence is given by relation as follows :

$A(n)=-6+(n-1)\dfrac{1}{5}$

For the first term, put n = 1. So,

$A(1)=-6+(1-1)\dfrac{1}{5}\\\\A(1)=-6$

For fourth term, put n = 4. So,

$A(4)=-6+(4-1)\dfrac{1}{5}\\\\A(4)=\dfrac{-27}{5}\\\\A(4)=-5\dfrac{2}{5}$

For tenth term, put n = 10. So,

$A(10)=-6+(10-1)\dfrac{1}{5}\\\\A(10)=-6+\dfrac{9}{5}\\\\A(10)=\dfrac{-21}{5}\\\\A(10)=-4\dfrac{1}{5}$

Hence, the correct option is (C).

-8, 1, 10...<br> n<br> What is a formula for the ninth term of the given sequence

krek1111 [17]

9514 1404 393

Answer:

a9 = -8 +9(9 -1)

Step-by-step explanation:

The given sequence has a common difference of 1-(-8) = 10-1 = 9, and a first term of -8. The formula for the n-th term of such an arithmetic sequence is ...

an = a1 +d(n -1) . . . . . first term a1, common difference d

For the parameter of this sequence, a1=-8 and d=9, the n-th term is ...

an = -8 +9(n -1) . . . . formula for the n-th term

Then the formula for the 9th term is ...

a9 = -8 +9(9 -1)

Solve for x and then part b) find JL. Have no clue how to go about this

Igoryamba

Answer:

x = 4
JL = 16

Step-by-step explanation:

a) You go about this by using the given equation.

Left + Right = Total

JK + KL = JL

(2x -3) + 11 = 4x

8 = 2x . . . . . simplify, subtract 2x

4 = x . . . . . . divide by 2

b) JL = 4x = 4·4

JL = 16
