Answer: 80
Step-by-step explanation:
7824/10 = 782.4
The value represented by 8 is 80 or 8 tens.
Betina is 155 centimeters tall or 1 meter and 55 centimeters
1 meter = 100 centimeters
100 + 87 = 187 , Brian’s height in centimeters
Since Bonnie is 58 centimeters shorter we will subtract 187-58 which gives us 129 centimeters.
Betina is 26 centimeters taller than Bonnie so we add 26+129 =155
Therefore Betina is 155 centimeters tall or 1 meter and 55 centimeters.
Hope this helped! :)
Answer:
B) A random sample may represent the population <em>is your best answer.</em>
Step-by-step explanation:
Note that the answer choice says "may", which means that it doesn't <em>always</em> represent the population. Random samples means that they ask random people, and do not have a certain rule that they have to follow (such as recipients can only be a certain race, age, etc.) and that they can ask anybody they meet. This can give not only a higher chance of a general population's opinion, but also makes sure that there is not a high chance of obtaining misleading information.
For example, a random survey would not take place at a rally, in which most of the people would believe the same thing, and would answer fairly the same for the survey. Instead, a random survey may be taken at a busy intersection during the time when most people are out. You must note that though it has the best chance of getting a <em>more accurate</em> representation, it still isn't the most accurate. For the best accuracy, <em>everyone would have to answer the survey in which the survey question would affect</em>.
