Answer:
50%, 68.26%, 95.54%
Step-by-step explanation:
Let X be the day care costs
X is N(10000, 2000)
Since normal distribution is symmetrical about the mean we get
above 10000, exactly 50% of day care cost would be .
Between 8000 and 12000,
=
Between 6000 and 14000
%
Parallel means the slopes are the same
Perpendicular means they have opposite reciprocal slopes.
We can apply these concepts to this question. Although they are opposites of each other, they are not reciprocals.
So, the answer is neither

It's not compounded interest, you just get $3.20 every year.
$100 * 0.032 = $3.20
$3.20 * 3 years = $9.60
8 and .25 are rational numbers because integers are negative and whole numbers don't include decimals and rational numbers can include whole number like 8 or 8/1 and .25.
