The standard error for the distribution of exam grades is 1.482.
Answer:
x < -3 or 2 < x < 7
Step-by-step explanation:
You could set up the equation as X^2=4X (3), and then simplify the equation to X^2 =12X, you can divide X from both sides, leaving you with X=12
First, we need to move the decimal point directly in front of the repeating part. To do this, we need to move it two places to the right, which we can do by multiplying by 100.
100 × 0.2045454545 = 20.45454545
Now we need to subtract our original number.
Now we put that over 99 (that's one less than our 100 from earlier)
Our fraction is shaping up, but we shouldn't have a decimal in there. Let's multiply the top and bottom by 100 to get rid of it.
We're going to have to do some simplifying. (the top and bottom are both clearly divisible by 5 and then some)
<em> done!</em>
8:24
4:12
100:300
All you have to do is multiply both sides by the same number to get an equivalent ratio.
