Answer:

see below

Step-by-step explanation:

6, 2, 7, 12, 6, 1, 7, 1, 9, 7, 8

First put the numbers in order from smallest to largest

1,1, 2,6,6, 7, 7, 7, 8, 9, 12

The mean is adding all the numbers and dividing by the number of numbers

( 1+1+ 2+6+6+ 7+ 7+ 7+ 8+ 9+ 12 )/11

66/1 =6

The mean is 6

The median is the middle

There are 11 terms

11/5 = 5.5 so 6 is the middle number

1,1, 2,6,6, 7, 7, 7, 8, 9, 12

7 is the median

Mode is the most often

7 appears three times so it is the mode

How do you solve this equation?

Travka [436]

Exponentail thingies

easy, look at all them them, see that they have 5 in common?
rremember how esay it was to factor
ax^2+bx+c=0

now we have
5^(2x)-6(5^x)+5=0
remember that 5^(2x)=(5^2)^x or (5^x)^2
in other words, we can rewrite it as
1(5^x)^2-6(5^x)+5=0
if yo want, replace 5^x with a and factor
1a^2-6a+5=0
(a-1)(a-5)=0
a=5^x
(5^x-1)(5^x-5)=0
set each to zero

5^x-1=0
5^x=1
take the log₅ of both sides
x=log₅1

5^x-4=0
5^x=4
take the log₅ of both sides
x=log₅4

x=log₅1 and/or log₅4

second quesiton

same thing

1(2^x)-10(2^x)+16=0
factor
(2^x-8)(2^x-2)=0
set each to zero

2^x-8=9
2^x=8
x=3

2^x-2=0
2^x=2
x=1

x=3 or 1

first one
x=log₅1 and/or log₅4
second one
x=1 and/or 3
