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%
It’s 3/12 you just need to find common multiples
First subtract the number that did, to find the number that didn't.
1300 - 520 = 780 customers did not order coffee.
Now divide the number who didn't order coffee by total number of customers:
780 / 1300 = 0.6
Multiply by 100 to get the percent:
0.6 x 100 = 60% did not order coffee.
Using proportions, it is found that both spaces have the same brightness, as both have 3 candles per m².
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
For Nayeli and Citlali, the rate of candles per m² is given by:
- N = 12/4 = 3 candles per m².
- C = 30/10 = 3 candles per m².
Hence both spaces have the same brightness, as both have 3 candles per m².
