Answer:
129°
Step-by-step explanation:
Given:
Interest = 4,275
interest rate = 2.5%
term = 18 years
Principal = ?
Interest = Principal * interest rate * term
4,275 = P * 2.5% * 18
4,275/ (2.5% * 18) = P
4,275 / 0.45 = P
9,500 = P
Your mom deposited 9,500 when you were born.
Answer:
The probability that a worker makes between $400 and $450 is .3413 using the calculator and .34 using the empirical rule.
Step-by-step explanation:
There are two ways to approach this problem.
The first way is to find the <u>z-score</u> corresponding to $400 and $450 weekly wage and find the p-value in between these values.
If you use the normalcdf function on your calculator and put 0 and 1 as the lower and upper bounds, respectively, you will get an area of .3413.
Another way of looking at this problem is to recognize that the weekly wages given are the mean and one standard deviation above the mean.
We can use the <u>Empirical Rule</u>, <em>68-95-99.7</em>, in order to see that going one standard deviation above the mean would be an area of 68/2 = .34.
I've attached an image that shows you what the normal curve looks like.
