Answer:
6
Step-by-step explanation:
There are only 6 significant digits because in total there are 9 digits. We do not need the first 2 0's, so now we only have 7 digits. But the question is do we really need the last 0? The answer is no. No, you do not need the last 0 because we already know that it's .0049, and the 0 is just an extra.
So without all the insignificant 0's, the number would look like this:
13.0049
Answer:
The approximate sample proportion is 0.59, which means that 41% of the subscribers surveyed most often listen to music somewhere other than in a vehicle.

Answer:
b = 80
Step-by-step explanation:
Given that,
x² + bx - 81
To find,
value of b
What is factorable?
A polynomial equation with highest degree 2 is if factorable when
- we can find two terms which when multiples = -81x², <em> ( x² * - 81 = -81x² ) </em>
- and when add = bx
possible factors:
- -1x * 81x = -81x² (Accepted)
- 1x * -81x= -81x² (rejected)
- 9x * -9x = -81x² (rejected)
- -9x * 9x = -81x² (rejected)
Only when -1x , 81x is added -1x + 81x = 80x
so, bx = 80x
b = 80
<h3>The equation is x² + 80x - 81</h3>
3 * N = 1
The multiplicative inverse is just the reciprocal of the number. The reciprocal is just " flipping " the number. So the reciprocal of 3 (or 3/1) is 1/3. And any time u multiply a number by its multiplicative inverse (reciprocal), the result is 1
3 * 1/3 = 3/3 = 1.....so N is ur multiplicative inverse
