Answer:
20% of the class earned a D
Step-by-step Explanation:
Step 1: Determine the total number of students represented on the graph:
9 students => D
5 students => C
14 students => B
17 students => A
Total number of students = 45
Step 2: Express each category of students who scored a particular grade as a fraction and as percentage.
9 students => D => => as percentage, we have
5 students => C => => as percentage, we have
14 students => B => => as percentage, we have
17 students => A => => as percentage, we have
Step 3: Check each statement to see if they are true or not based on the calculations above.
Statement 1: "⅕ of the students earned a C."
This is NOT TRUE From our calculation, ⅑ of the students earned a C.
Statement 2: "3% more students earned an A than a B." This is also NOT TRUE.
37.8% earned A, while 31.1% earned a B. Thus, about 6.7% more students earned an A than a B.
Statement 3: "20% of the class earned a D". This is TRUE.
Check calculation in step 2.
Statement 4: "¼ of the class earned a B". This is NOT TRUE.
¼ is 25% of the class. Those who earned a B account for 31.1% not 25% (¼ of the class).
The correct statement is: "20% of the class earned a D"

Answer:
input is your hours
output is your money
domain is all numbers greater than/equal to 0
range is any number greater than/equal to the amount of money you make per hr
Andrew’s total wages are a function of the number of hours he works. The input of this function is the total number of hours worked. The output is the total wages earned.
The domain is the number of hours that Andrew can work in a week. A week has 168 hours. He works for 30 hours regularly. So, the domain is D = {30, 31, 32, … , 168}.
Of course, it is unrealistic to expect Andrew to work 24 hours a day for an entire week. 168 simply represents the total possible hours to work.
The range is the money Andrew can make working his usual 30 hours plus any extra hours at $5 per hour: R = {120, 125, 130, ... , 810}.

Answer:
504.999...
Step-by-step explanation:
505 rounds to 510, but a number that is infinitessimally smaller rounds to 500.
Unfortunately, for any number you can write that rounds to 500, there are an infinite number of numbers that are greater and still less than 505.
In short, there is no "greatest number" that is less than 505—unless you put additional restrictions on it, like the number of digits that can be used to express it, for example.
