Find the z score for each price range:
Z score for 37 = 37-45/5 = -1.6 from z table -1.6 = 0.0548
Z score for 59.35 = 59.35-45/5 = 2.87
From the z table 2.87 = 0.9979
Now to find the proportion between the two prices subtract:
0.9979 - 0.0548 = 0.9431
Answer:
A. an = -3 + 4(n - 1)
Step-by-step explanation:
The sequence given follows an arithmetic progression. This means the following term can be gotten by simply adding a factor to the previous term (or even the first term).
They are represented by the equation:
y(n) = a + r(n - 1)
Where y(n) is the nth term
a = first term
r = factor
Let us compare this with the sequence given:
The first term, a, is -3
We can get the factor, r, by using the second term, which is 1. This means n = 2.
=> 1 = -3 + r (2 - 1)
1 = -3 + r
=> r = 1 + 3 = 4
Therefore, putting a = -3 and r = 4, the sequence can be written as:
y(n) = -3 + 4(n - 1)
I think is is (-6,1.5) correct me if i am wrong
