The outlier  is 20

it affect the mean because

1)32 +40+34+ 31 +20+ 36 +40+31=264

2) 264 divided by 8= 33

so it gives you an odd number

Write the equation of the line in slope intercept form that goes through points (1,8) and (5,20)
pantera1 [17]

Answer:

y=3x+5

Step-by-step explanation:

Point slope equation:

y=mx+b

m-slope, b- is y-intercept

equation given 2 points

y-y1 = m(x-x1)

For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3

y-8 =3(x-1)

arange it in point slope format

y-8=3x-3

y=3x-3+8

y=3x+5

If n is an​ integer, n times •180degrees° represents an integer multiple of 180degrees° and​ (2nplus+​1) times •90degrees° repre
NISA [10]
Solution: csc stands for cosecant 
csc (2n+1) x 180˚
= Csc (360n +180)
= csc (180) and the csc has a period of 360˚
= 1/ sin (180) 
As sin 180 = 0 so, 
csc ((2n+1) x 180 degrees) is undefined as 1/0 is undefined when you calculate it in the calculator.

A function is given: f (x) = 2x + 3<br> What is the value of f(-2)?
Nadusha1986 [10]

Answer:

f(-2) = -1

Step-by-step explanation:

-2 is x, so replace x as -2 into the equation

f (-2) = 2(-2) + 3

f (-2) = -4 + 3

f (-2) = -1

Write an recursive formula for An, the nth term of the sequence<br> 5, -2, -9,
oksian1 [2.3K]

Given:

The given sequence is:

5,-2,-9,...

To find:

The recursive formula for a_n, the nth term of the sequence.

Solution:

We have,

5,-2,-9,...

Here, the first term is 5.

-2-5=-7

-9-(-2)=-9+2

-9-(-2)=-7

The common difference is -7.

The recursive formula for the nth term of the sequence is

a_n=a_{n-1}+d

Where, d is the common difference.

Putting d=-7 in the above formula, we get

a_n=a_{n-1}+(-7)

a_n=a_{n-1}-7

Therefore, the recursive formula for the nth term of the sequence is a_n=a_{n-1}-7.
