<span>- - Star to simplify both sides of the equation.

</span>18-4x=-2&#10;

<span>- - Now you have top subtract 18 from both sides.
</span>
-4x+18-18=-2-18
- - Solve: 
-4x=-20&#10;

<span>- - And divide both sides by -4.

- - Solve: 
</span>\frac{-4x}{-4} =  \frac{-20}{-4}

x=5

First u would take the 18 and - it on both sides
18 - 18 - 4x = -2 - 18 
which would be 
-4x = -20 
then u would divide 4 on bothe sides 
-4x/4 = -20/4
which would give u 
- x = - 5
this is the answer for the negative x 
for positive u would flip the answer 
so 
x = 5 which then = 4
x=5 is ur answer 
hope this helps or u understand wat im sayin

What is the value of log279?<br> -3/2, -2/3, 2/3, 3/2
kaheart [24]

Answer:

2/3

Step-by-step explanation:

log27(9)

Factor the number: 27=3³

= log3³(9)

Apply log rule: loga^b(x) - 1/b loga(x).

log3³(9) =1/3 log3³(9)

=1/3 log3³(9)

Factor the number: 9=3²

=1/3 log3³(3²)

Apply log rule: loga(a^b) =b

log3 (3²) =2

1/3×2

=2/3

CitiBank recorded the number of customers to use a downtown ATM during the noon hour on 32 consecutive workdays. 39 41 25 17 48
zaharov [31]

Answer:

Mean = 31.22

Midrange = 28.50

Geometric mean = 28.74

Trimmed mean = 31.56

Step-by-step explanation:

Given the data :

39 41 25 17 48 29 31 17 24 36 17 24 40 38 42 11 43 47 27 25 17 23 43 20 32 48 26 26 9 46 44 44

Ordered data :

9, 11, 17, 17, 17, 17, 20, 23, 24, 24, 25, 25, 26, 26, 27, 29, 31, 32, 36, 38, 39, 40, 41, 42, 43, 43, 44, 44, 46, 47, 48, 48

The mean, xbar :

Xbar = Σx / n = 999 / 32 = 31.22

The midrange : (maximum - minimum) / 2

Midrange = (48 + 9) / 2 = 57 / 2 = 28.5

Geometric mean :

(x1*x2*.. xn)^1/n

Geometric mean = (x1*x2*.. xn)^1/32 = 28.74

24% trimmed mean :

24% of 32 = 0.24 * 32 = 7.68 ; this mean cutting off 8 values from the top and bottom and calculating the mean of the remaining values.

Data left :

24, 24, 25, 25, 26, 26, 27, 29, 31, 32, 36, 38, 39, 40, 41, 42

Σx / n = 505 / 16 = 31.5625

Trimmed mean = 31.56
