<h2>the answer i thinkk is 2/20 because since there ae 20 children, then the brother and sister each have a 1% chance, hope this helped!</h2>
To solve this, we would need to figure out the values of
for which an absolute value is negative. From basics, you should know that an absolute value is always greater than or equal to 0.
If we rearrange this equation a little bit, we get,

So
<em>cannot </em>be negative. So,

For this to <em>have </em>a solution, k needs to be greater than or equal to
.
For <em>no solution</em>, k is less than -5. So, values of k which will make the equation to <em>not </em>have any solution is
.
ANSWER: 
Step-by-step explanation:
<u>Product property</u>
- If the bases are the same, you don't multiple them. However, if they are the same, you do multiple for example : (2³ * 2¹ = 2⁴.when the bases are the same) (2³ * 3¹ =6⁴. When the bases are not the same
- We add the index.
<u>Quotient</u><u> </u><u>property</u>
- Same here, if the bases are the same, they stay the way they were
- We subtract the index
<u>Power</u><u> </u><u>property</u>
- Here we multiple the index because of the bracket for example : (9²)²= 9⁴
<u>Negetive</u><u> </u><u>exponent</u><u> </u><u>property</u>
- When ever the index has a negative sign its convected to a fraction, for instance : 9¯² = 1 /9²
- Note, when it turns to a fraction th index becomes positive
Please consider the graph of the sphere.
We know that the volume of sphere is equal to
, where r represents radius of sphere.
We can see that diameter of sphere is 30 inches. We know that radius is half the diameter, so radius of the given sphere would be half of 30 inches that is
inches.





Therefore, the volume of the given sphere is
and option B is the correct choice.
