Answer:

z= -24

Step-by-step explanation:

First, subtract 36 to both sides.

z/-3+36= 44

      -36  -36

z/-3= 8

Now, multiply both sides by -3 to isolate the variable.

<u />\frac{z}{-3} ×(-3)= 8(-3)

z= -24

Answer:

z = -24

Step-by-step explanation:

<h2><u>Solving for z</u></h2><h3>we have to make z the subject of formula :</h3>

\frac{z}{-3} + 36 = 44\\

we can move the 36 to the other side of the equal sign

<u><em>NOTE: </em></u>moving a number of one side of the equal sign to another , this changes the sign of the number ( eg +36 becomes -36 )

\frac{z}{-3}  = 44- 36

\frac{z}{-3} = 8

z = 8 * -3

<h3><u>z = -24 </u></h3>

Answer:

f(x) = 8(1/2)^x.

Step-by-step explanation:

According to the graph, there is a point at (0, 8) and (1, 4).

That means that when x = 0, y = 8.

8 = a(b)^0

1a = 8

a = 8

That means that a = 8, and when x = 1, y = 4.

4 = 8(b)^1

4 = 8b

8b = 4

b = 4/8

b = 1/2

So, f(x) = 8(1/2)^x.

Hope this helps!

Part a)

MAD = median of absolute deviations

MAD = median of the set formed by : |each value - Median|

Then, first you have to find the median of the original set

The original set is (<span>38, 43, 45, 50, 51, 56, 67)


The median is the value of the middle (when the set is sorte). This is 50.


Now calculate the absolute deviation of each data from the median of the data.

1) |38 - 50| = 12
2) |43 - 50| = 7
3) |45 - 50| = 5
4) |50 - 50| = 0
5) |51 - 50| = 1
6) |56 - 50| = 6
7) |67 - 50| = 17

Now arrange the asolute deviations in order

(0, 1, 5, 6, 7, 12, 17)

The median is the value of the middle: 6.

Then the MAD is 6.

Part b) MAD represents the median of the of the absolute deviations from the median of the data.
