The first one is correct.
Answer:
10 calories per minute
Step-by-step explanation:
We do not have much information to go on such as the speed that Tai is biking or his/her weight. Regardless we can use the data gathered by the University of Harvard which after a study came up with the following results. Their results showed that if an individual bikes at a speed of 13 mph and are around 155 pounds they will burn calories at a rate of 10 calories per minute. Therefore we can assume that Tai is burning roughly 10 calories per minute. This rate increases if the person bikes at a faster speed or weighs more as they are exerting more energy.
When dividing 250,000 by 100, the digits in the quotient move by 2 places to the right.
<u>Step-by-Step explanation:</u>
Here we have , to find out that When dividing 250,000 by 100, the digits in the quotient move how many places to the right . Let's find out:
⇒ dividing 250,000 by 100
⇒ 250,000 / 100
⇒ 
⇒ 
⇒ 
Initially we had 250,000 of 6 digits and now after dividing 250,000 by 100, we have 2500 of 4 digits ! So , Number of places quotient shift to right is:
⇒ 
⇒ 
Therefore, When dividing 250,000 by 100, the digits in the quotient move by 2 places to the right.
The distribution shape that tells us for which it is best to use the mean is the skewed.
<h3>What is the mean?</h3>
This is the term that is used to refer to the average score that exists in a data set.
In the question, these are the reasons why the other options are not correct
When we say Bimodal we are talking about the 2 modes that are in a symmetric distribution. This has nothing to do with the mean
The bell shape has to do with how the normal distribution is when it is drawn. It would create a bell shape hence the mean is not useful.
symmetric has to do with the fact that there are mirror images when the vertical line is drawn in the distribution.
Uniformed shapes tells us that the classes are made up of the same frequency all through.
The skewed shape is what tells us if the median is more or if it is less.
Hence we have the answer that the distribution shapes for which it is most often appropriate to use the mean is the skewed.

Answer: 243 people
Step-by-step explanation:
ration of 7 children to every 2 caretakers, and there are 189 children. So, since ratio of children is 7, divide 189 by 7 and get 54. Then multiply by 2 since that is the ratio for caretakers to get 54 caretakers. You can check these numbers by putting in the calculator 189/54, it simplifies to 7/2. Add 54 and 189 to get total number of people which is 243.
