The question is about work and efficiency and requires solving a system of equations to find the individual work rates of people from different nationalities. However, because we have insufficent data (two equations but three unknowns), we cannot find a unique solution and thus can't determine how long it would take for one Chinese, one Indian, and one Japanese to complete the work together.
The student's schoolwork question involves solving a problem related to work and efficiency, which is a part of mathematics, specifically related to rate and work problems.
First, let's find the rate of work done by individuals from each nationality. We can set up the equations based on the given information:
Let's denote the efficiency of one Indian as I, one Chinese as C, and one Japanese as J.According to the given information:We will need to solve this system of equations to find the individual efficiencies I, C, and J. However, we have two equations and three unknowns, so we cannot find unique solutions for I, C, and J unless we have one more equation or information.
Since we cannot determine the individual efficiencies with the given information, we cannot determine how long it would take one Chinese, one Indian, and one Japanese to complete the work.

What is the slope of the line represented by the equation y = – 2/3- 5x?
A. -5
B. -2/3
C.2/3
D. 5
PLS HELP TY
Answer:
Option A The slope of the line is [tex]-5[/tex]
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
[tex]y=mx+b[/tex]
where
m is the slope
b is the y-intercept
we have
[tex]y=-\frac{2}{3}-5x[/tex]
Rewrite
[tex]y=-5x-\frac{2}{3}[/tex]
therefore
[tex]b=-\frac{2}{3}[/tex] -----> the y-intercept
[tex]m=-5[/tex] ------> slope

a set of data can have no mode true or false
True, A set of data can indeed have no mode. In statistics, the mode represents the value(s) that appear most frequently in a dataset.
However, there are scenarios where no value occurs more frequently than others, resulting in a lack of a mode. This can happen in several situations. For example, in a uniform distribution where all values occur with equal frequency, or in a dataset with no repetition of values (each value occurs only once). Additionally, if the data is continuous and does not have distinct categories or intervals, it may not have a mode. In summary, while a mode is a common descriptive statistic, it's not a requirement for every dataset, and some datasets do indeed have no mode.
