Hello,
The relationship between the number of hours a plumber works and the total work fee she charges is proportional. Her fee for 5 hours of work is $350.
Which of the following could be combinations of values for the plumber's work hours and total work fee she charges?
Solution:
Find similar ratios to 5/350
Similar Ratios,
1/70
2/140
3/210
3.5/245
4/280
6/420
7.25/507.50
Answers:
B) 3.5 hours and $245
C) 6 hours and $420
D) 7.25 hours and $507.50
You can divide the whole expression by -3:
Recalling that
Let's compare the middle term:
So, we want to complete
Which differs from by 16. So, if we add 16 to both sides, we have
Answer: B 35/4
Step-by-step explanation:
We're going to solve each of the systems to determine the solution.

The central tendency researcher use to describe these data is "mode".
<h3>What is mode?</h3>
The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.
Calculation of mode is done by-
- The number that appears the most frequently in a piece of data is its mode.
- Put the numbers in ascending order by least to greatest, then count the occurrences of each number to quickly determine the mode.
- The most frequent number is the mode.
- Simply counting how many times each number appears in the data set can help you identify the mode, which is the number that appears the most frequently in the data set.
- The figure with the largest total is the mode.
- Example: Since it happens most frequently, the mode for the data set [5, 7, 8, 2, 1, 5, 6, 7, 5] is 5.
