The mean absolute deviation is 10.52.
<h3>What is the mean absolute deviation?</h3>
The mean absolute deviation of a dataset is the average distance between each data point and the mean. It is a measure of variation of a data set.
MAD =1/n ∑ l x - m(x) l
Where:
n = total numbers in the data set
x = number
m(x) - median
The first step is to determine the mean of the data set: (42 + 31 + 1 + 1 + 2 4+ 5 + 6 + 7 + 3) / 10 = 10.2
Find the absolute value of the difference between the number and the mean. Add the result | (42 - 10.2) + (31 - 10.2) + (1 _ 10.2) + (1 - 10.2) + (2 - 10.2) + (4 - 10.2) + (5 - 10.2) + (6 - 10.2) + (7 - 10.2) + (3 - 10.2) = 105.2
Divide the sum by the total number in the dataset = 105.2 / 10 = 10.52

Answer:
Step-by-step explanation:
hello :
the form : g(x)=a/(x+h)+k
1 ) <u>g(x)=7x+17/x+2 :</u>
you can write : 7x+17 = 7(x+2)+3
so : g(x) =(7(x+2)+3)/(x+2) = 7(x+2)/(x+2) +3/(x+2)
g(x) = 7+ 3/(x+2) or g(x) = 3/(x+2) +7 compare with g(x)=a/(x+h)+k
a=3 and k=7 and h=2
2) <u>g(x)=5x-7/x-3 :</u>
you can write same method for 1 ..... here is other method :
g(x)=a/(x-h)+k = (a+k(x-h))/(x-h)
g(x) = (kx+a-kh)/(x-h) h=3
so : k=5 and a-kh = -7
a-(5)(3)=-7 a = 8
g(x) =8/(x-3) +5
Answer:
-3/2, 1.25, |-9/4|, 2.5, 121
Step-by-step explanation:
Convert all numbers to a decimal
-3/2 = -1.5
|-9/4| = 2.25
2.5 = 2.5
121 = 121.0
1.25 = 1.25
Now put them in order from least to greatest.
-3/2, 1.25, |-9/4|, 2.5, 121
It is 9 truffles each day so eleven days
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r)
The sequence rule for a geometric sequence is:
a(n)=ar^(n-1)
Not sure what they mean by "graph the six terms"
The sum of the first six terms is in this case:
s(6)=5(1-1.25^6)/(1-1.25)
s(6)=56.2939453125
The first six terms in sequence is in this case:
a(n)=5(1.25)^(n-1) so
5, 6.25, 7.8125, 9.765625, 12.20703125, 15.2587890625
