11.25 rounded to the nearest hundredth is 11.25
The 2 is in the tenths place, and the five is in the hundredths place. In order to round to the nearest hundredth, there must be a thousandths number to determine it, which there is not.
Consecutive odd integers. X
X+2
X+4
The largest is x+4. So it looks like this. X+4-2x =-13
-1x+4 = -13
Subtract 4 from both sides. -1x +4-4. = -13 -4
-x = -17
X=17. So the smallest number is 17. The largest is 17 +4. =21
The answer is 21
There are different kinds of curves. All density curves must satisfy the conditions that;
- The curve does not go below horizontal axis
- The total area under the curve is = 1.
<h3>What conditions must a density curve adhere to?</h3>
Note that a probability density curve must satisfy two key requirements: that is;
- F(x) have to be nonnegative for all value of the random variable.
- The integral that is over each values of the random variable have to be equal to one.
A density curve is regarded as a curve that is said to be always on or found above the horizontal axis, that is, it is always negative and its area is equal to 1 under it.
