Answer:
The -1 came from factoring.
The equation is multiplied by 8 because 8 could be pulled from 16x-8.
16 can be divided by 8 2 times and 8 can only divided by 8 once.
so factoring it makes the equation 8(2x-1)
Answer:
a) 376.66
b) Option 2: No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) 377
d) 40.77%
Step-by-step explanation:
a) 37% of 1018 is;
37/100 × 1018 = 376.66
b) Thus, the result in a above is not a whole number. Thus;
No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) from a above a, we got a value of 376.66.
Now the actual number would be preferably an integer. Thus, actual number is approximately 377.
d) percentage of respondents said that cellular phones are not at all harmful = 415/1018 × 100% = 40.77%
