Answer: Yes, we have.
Step-by-step explanation:
Going by the details provided, Probability of success of choosing a citizen with a fitness band 27%
The probability function for expected value shows the Formula to know with sufficient dependence what proportion of the sampled people will have the fitness band.
Since 27% of 500 = 135.
and 135 is more than a quarter of 500(125), then we have enough Evidence that more than a quarter of this age group own a fitness band.
1 Simplify 7x+16+47x+16+4 to 7x+207x+20<span> 7x+20=x<span>7x+20=x</span></span>
2 Subtract 7x from both sides<span> 20=x-7x<span>20=x−7x</span></span>
3 Simplify <span>x-7x<span>x−7x</span></span> to <span>-6x<span>−6x</span></span>
<span>20=-6x<span>20=−6x</span></span>
4 Divide both sides by −6 -20/6=x
5 Simplify 20/6 to 10/3 -10/3=x
6 Switch sides
x=-10/3<span><span><span> </span></span></span>
