Answer:
Step-by-step explanation:
[8/63] + [ 4/15 ]
= (120 + 652)/945
= 0.82
Answer:
B) Interquartile range
Step-by-step explanation:
Since there are some students that do not eat fast food at all, their amounts spent monthly would be $0. These are much different than the rest of the data, and thus are outliers.
Outliers can greatly affect the mean. This tells us the mean may not be the best measure.
Since the mean is affected by outliers, the standard deviation is not the best measure either.
Adding data points of 0 will also affect the range. This leaves the interquartile range as the better measure.
Answer:
Step-by-step explanation:
First of all, you add 1/3 and 4/5, so you get:
To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:
Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:
That's the sum of 1/3 + 4/5.
Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:
In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:
Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15.
Hope this Helps! :D
The statistical questions are:
- On average, how many books does each person in the United States read each year
- Which book was read most by students in the class, this summer
The non-statistical questions are:
- How many acts are there in the play Romeo and Juliet
- How many books are in the class right not
<h3>How to categorize the questions?</h3>
As a general rule, questions whose answers can be determined using a single data point are non-statistical questions.
Using the above rule, we have the non-statistical questions to be:
- How many acts are there in the play Romeo and Juliet
- How many books are in the class right not
As a general rule, questions whose answers cannot be determined using a single data point are statistical questions.
Using the above rule, we have the statistical questions to be:
- On average, how many books does each person in the United States read each year
- Which book was read most by students in the class, this summer
Also, both statistical questions are numerical
