Answer:182 ways

Step-by-step explanation:

Given

there are total of 10 workers in office

No of ways to select 4 workers out of 10 workers =^{10}C_4

=\frac{10\times 9\times 8\times 7}{4\times 3\times 2\times 1}=210

(b)If hugo and Viviana refuse to work together then

then no of ways in which hugo anf Viviana work together

=^{8}C_2=28

Therefore total no of ways in which Hugo and Viviana do not work together is =210-28=182\ ways

A medical plan requires a patient to pay a $25.00 copay plus 20% of all charges incurred for a medical procedure. If the average
miss Akunina [59]
Let the original bill be x, then the final bill after the charges been added are 1.2x+25, where 1.2 is the increase in the bill by 0.2 (100%+20% = 120% = 1.2)

The range of the original bill is 
200 < 1.2x+25 < 800, subtract each term by 25
175 < 1.2x < 775, divide each term by 1.2
145.83 < x < 645.83

Hence, the range of the original bill is between $145.83 and $645.83
