Answer:

C: Either the mean or median; both are 5

Step-by-step explanation:

MEAN: 5+2+4+8+6= 25 = 25/5= MEAN IS 5

MEDIAN: put it in order: 2,4,5,6,8

              cross out 2,8,4,6

              left over number is 5

             So median is 5

PLEASE HELP ASAP

Answer:

5

Step-by-step explanation:

Since the difference in each term number is 5, we put 5 in the place of the star.

Formula for constant difference in a pattern: Tn= an+b

a is the difference while b is the number that comes before the 1st term. So, the equation to find the nth term is Tn=5n+4.

Hope this helps and please give a brainlist, thank you!

PLEASE HELP<br><br> Which of the following is the inverse of f(x)=3-x/5
BabaBlast [244]

Answer:

f^-1(x) = 3 - 5x, second option

Step-by-step explanation:

To determine the inverse simply interchange the variables and solve for y;

f(x) = 3 - x / 5 -> Interchange the variables

x = 3 - y/5 -> Multiply either side by 5

5x = 3 - y -> Subtract three from either side

- y = 5x - 3 -> Divide either side by - 1

y = - 5x + 3

Your solution is f^-1(x) = 3 - 5x

let
x-----> </span>Susan's age
y---->  Steven's age

we know that
y+x=33-----> equation 1
3y-x/2=36----> multiply by 2----> 6y-x=72----> equation 2
adds equation 1 and equation 2

y+x=33
6y-x=72
-------------+
7y=105--------> y=15
x=33-y----> x=33-15----> x=18

the answer is
Susan's age is 18
Steven's age is 15
