Answer:
No, I don't believe that percent of girls born in china is 46.7.
Step-by-step explanation:
Given
Natural ratio of girls to boy =100:105
In China , the birth ratio = 100:114
Number of girls=46.7%
In our study
Number of girls=60
Number of boys= 90
Total number of birth =150
To find the percentage of girls in our study
Percentage of girls=40%
Therefore, the percentage of girls in our study is 40% not 46.7%
Hence, I don't believe that percentage of girls born in China is 46.7%.

<span>The answer would be C because you are subtracting 3 by a number(x) because you are REMOVING garbage. And if you remove the x from 3x and replace it with the number of weeks, you'll get the number of loads dumped. For example -3(5)+60. Follow your order of operations. Multiply first to get -15. Then add that to 60. You will get 45, which is the correct answer because in the problem, the number of loads are 45. Or how about this, -3(10)+60. Multiply first to get -30, then add positive 60 to get 30 overall. Since 30 is the number of loads removed in the problem, your answer is correct, thus, making the correct equation C.</span>
Is (x^3 -1)/x odd or even?
I believe the answer is even if you divide them out.
