Answer:
y = 4 * x
y is the number of students that Lorenzo surveys,
x is the number of students that Nicole surveys.
Step-by-step explanation:
Lorenzo surveys 24 students, so we can use this value as the left side of our equation.
The number of students that Lorenzo surveys is 4 times as many as the number of students that Nicole surveys, that is 6. So, we use the value of 6 in the right side of the equation, and multiplied by 4 (the expression "4 times as many as" means that one value is the second one multiplied by 4)
The expression that represents this is:
24 = 4 * 6
If we use the variable y to express the number of students that Lorenzo surveys and x to express the number of students that Nicole surveys, we can write this equation:
y = 4 * x
Employment impacts your Social Security and Medicare benefits because a worker pays a percentage of their income into these 'retirement insurance' schemes. Payroll taxes for these programs are shared by the employer and employee, with economists pointing out that the employer's share often ends up being covered by the employee through lower wages. Independent contractors have to cover both sides of the payroll tax.
Your current or future employment affects your Social Security and Medicare benefits in a few key ways. Firstly, workers pay a percentage of their income into Social Security and Medicare, which are forms of retirement insurance that provide income and health care benefits when they become elderly or sick. These are not 'insurance' in the traditional sense, but they function similarly, in that regular payments are made into the programs today in exchange for future benefits.
In terms of payroll taxes, both the employer and the employee contribute. An employee sees a deduction of 6.2% from their paycheck for Social Security, and 1.45% from Medicare. However, the employer's half of the taxes is often passed along to the employees in the form of lower wages, so in reality, the worker pays all of the payroll taxes. If you are a member of the “gig economy” and considered an independent contractor, you must pay both the employee and employer side of the payroll tax.

Step-by-step explanation:
If Marian travels, by car, on the highway. At 10 and 35 minutes he is at kilometer 25. After a period of time, at 11 and 15 minutes, he is at kilometer 100.
Total distance covered = 25km + 100km
Total distance covered by Marian = 125km
Total time taken by marian = 10hr 35min + 11hr + 15min
Total time taken by marian = (10+11)hr + (35+15)min
Total time taken by marian = 21hr 50mins
Total time taken by marian = 21 * 50/60 hr
Total time taken by marian (Duration) = 21.833hr
Average speed = Total distance covered/Total time taken
Average speed = 125/21.833
Average speed = 5.725km/hr
Convert to m/s
5.725km/hr = 5.725*1000/3600
5.725km/hr = 5725/3600
5.725km/hr = 1.5903 m/s
Hence the average speed expressed in SI unit is 1.5903 m/s
