We must first solve the number of fiction and nonfiction books
if x is the number of fiction books and
y is the number of nonfinction books
Then,
x + y = 400
x = y + 40
Solving the system of equations:
x = 220
y = 180
Therefore, the probability that Audrey and Ryan will get both nonfiction books is
P = 180/400 + 179/399
P = 0.8986
Answer:
The strong linear relationships are:
r = 0.95
r=-0.83
Step-by-step explanation:
When we have points whit apparent linear tents, we can fit the curve to a line and when the correlation coefficient (r) is equal to 1, we have perfect correlation and when r is equal to 0 we do not have a correlation.
Therefore r = 0.95 suggest strong linear relationships.
Now, we can use the same analysis with a negative value of r, so r = -0.83 is strong too.
I hope it helps you!
We''ll use $100 and $200 for the investment amounts.
Using the attached formula,
Years = natural log (200 / 100) / .12
Years = natural log (200 / 100) / .12
Years = 0.69314718056 / .12
Years =

Just divide 67.5 by 1.5.Your answer is 45.
Well, then you have to add t, so the final answer is 45t.
Hope this Helps :)
