Answer:
a = 3
Step-by-step explanation:
9-3=6
6/2=3
Answer:
d
Step-by-step explanation:
A(n) = 1 - 0.1(n-1)
A(1) = 1- 0.1*(1-1) = 1 - 0.1*0 = 1
A(2) = 1- 0.1*(2-1) = 1 - 0.1*1 = 1- 0.1 = 0.9
A(3) = 1 - 0.1(3-1) = 1 - 0.1*2 = 1-0.2=0.8
Method:
A(1)=1
D = A(2)-A(1) = 0.9 - 1 = -0.1
A(n) = A(1)+(n-1)*d = 1 + (n-1)*(-0.1)
= 1 - 0.1(n -1)
To solve this problem, we should remember that the percentile rank of a single
value is the rank of that value in the series of data set when that data set is
arranged in ascending order.
Therefore arranging the data set, gives the sequence:
5581, 5700, 5700, 5896,
5972, 5993, 6075, 6274, 6283, 6381
<span>Since we are to find the
30th percentile (30 %) and there are a total of 10 values, therefore
the 30th percentile is:</span>
10 * 30% = 3
<span>This means we look for
the 3rd number in the ordered sequence.</span>

<span>Answer: 5700 is the 30th
percentile of the series</span>
Answer:
y=-5x-3
Step-by-step explanation:
Parallel means that it has the same slope (-5)
then, using the point slope formula,
y-(-2)=-5(x-(-1))
y+2=-5x-1
y=-5x-3
