About 4 out of every 5 people are right-handed. If there are 30 students in a class, how many would you expect to be right-handed? How many to be left-handed?

Answer:

A: 20pi

Step-by-step explanation:

c=2(pi)r

c=2(pi)(10)

c=20(pi)

c=62.8

Answer:

D=[0, 64]

Step-by-step explanation:

The domain of a function is the interval of all possible values of the independent variable. In this situation, the independent variable is the number of people on the ferris wheel 'p'. Since the capacity is 64 people, the possible interval for 'p' is from 0 to 64 people. Therefore, the domain is;

D=[0, 64]

To calculate the cost per patient over the four-year period, we need to add up the costs for each year and then divide by the number of years.

The costs per patient for the four years are:

Year 1: $43

Year 2: $46.5

Year 3: $49.8

Year 4: $53.63

To find the total cost over the four years, we add up these costs:

$43 + $46.5 + $49.8 + $53.63 = $193.93

Now, we divide the total cost by the number of years (which is 4) to find the average cost per patient over the four-year period:

$193.93 / 4 = $48.48

Therefore, the cost per patient over the four-year period is approximately $48.48.

Final answer:

The cost per patient over the four-year period is $193.16.

Explanation:

To find the cost per patient over the four-year period, we need to calculate the percent increase for each year and then multiply the percent increase by the previous year's cost. Here are the steps:

1. Calculate the percent increase for each year:
   • From $43 to $46.5: ($46.5 - $43) / $43 * 100% = 8.14%
   • From $46.5 to $49.8: ($49.8 - $46.5) / $46.5 * 100% = 7.10%
   • From $49.8 to $53.63: ($53.63 - $49.8) / $49.8 * 100% = 7.70%
2. Multiply the percent increase by the previous year's cost for each year:
   • Year 1: $43 * (1 + 8.14%) = $46.57
   • Year 2: $46.5 * (1 + 7.10%) = $49.85
   • Year 3: $49.8 * (1 + 7.70%) = $53.74
3. Add the costs for each year: $43 + $46.57 + $49.85 + $53.74 = $193.16

Therefore, the cost per patient over the four-year period is $193.16.
