The situation above is an arithmetic sequence with the third term (a3) equal to $285 and sixth term (a6) equal to $510. To determine the nth term of the arithmetic sequence, use the equation,
an = a1 + (n - 1)d
where a1 is the first term and d is the common difference. To solve for these, use the given values,
285 = a1 + (3-1)(d)
510 = a1 + (5 -1)(d)
Solving for the unknowns gives an answer of a1 = 60 and d = 112.5.Thus, the equation is,
y = 60 + 112.5x
Answer:
0.67449
Step-by-step explanation:
Let be the 3rd quartile of normal distribution .
-z-score corresponding to the upper quartile can be calculated in excel as:
- In Excel, click on any empty cell'
- Type the function NORMINV
- Enter the probability as 0.75, mean= 0 and standard deviation=1
- Click the enter button.
-The output is 0.67449. Hence, the z-score corresponding to the upper quartile (Q3) of a normal distribution is 0.67499
