Answer:
0
Step-by-step explanation:
The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:
Already with the figure we can solve the question.
We have that the average exchange rate in this case would only take the normal slope between those 2 lines
. Furthermore we know that the slope (m) is given by:
m = (y2-y1) / (x2 - x1)
From the graph we have to:
y2 = 0
y1 = 0
x2 = 5
x1 = 3
we replace:
m = (0-0) / (5 - 3)
m = 0
Therefore the average rate is 0.
Answer:
1.25
Step-by-step explanation:
Give the data:
X : 1 1/2 ___ 0 _____ 4 ______ 2 1/2
Mean absolute deviation (MAD) :
Σ|x - xbar| ÷ n
xbar = Σx/ n
Σx = (1 1/2 + 0 + 4 + 2 1/2) = 8
xbar = 8/4 = 2
|x - xbar| :
|1 1/2 - 2|= 1/2
|0 - 2| = 2
|4 - 2| = 2
|2 1/2 - 2| = 1/2
Therefore,
MAD = (1/2 + 2 + 2 + 1/2) / n
MAD = 5/4
MAD = 1.25
Could you respond with the colors to the key at the bottom? I cannot tell with this picture.
If BD = 12x + 36
And BD = BC +CD = 3 + 1 = 4
BC = (12x + 36)/4 x 3
= 12(x+ 3) /4 x3
= 3(x+3) x 3
= 9x + 27
Likewise,
FE = 12(x + 3) /3 x 1
= 4x + 12
Area = 1/2 x (BC + FE) x DE
= 1/2 x (9x + 27 + 4x + 12)x (x+1)
= 1/2 x (13x + 39) x (x +1)
= 1/2 x 13x2 + 52x + 39
Hope this helps,

The speed is 64 miles per hour
Step-by-step explanation:
Lets define speed first.
"Speed is the distance per unit time"
Speed is denoted by s.
Given
Distance = d = 160 miles
Time = t = 2.5 hours

Hence,
The speed is 64 miles per hour
Keywords: Speed, distance
