Which of the following is the difference between the mean and the median number of tickets sold at the 5 schools?

School	Number of Tickets Sold
Lincoln	200

Washington	300
Adams	150
Jackson	275

We can solve this using a proportion, since the dose is directly proportional to the child's weight.

Step 1: Set up the proportion

20 mg/50 lb=x/ mg35 lb

Step 2: Solve for xxx

x =

=700/50

=14 mg

Correct answer: C. 14 mg

To display how often students get up after 8 a.m. on each day of the week, we are dealing with categorical data (days) and their frequencies.

Best option:

• A. Scatterplot – Not suitable for categorical data
• B. Pie graph – Good for showing parts of a whole, but not ideal for comparing frequencies across categories
• C. Histogram – Used for continuous numerical data, not categories like days
• D. Bar graph – Best choice for showing frequencies across distinct categories (like days of the week)

Correct answer: D. Bar graph

Let's convert all the values to decimals for easy comparison:

• A. 4.4 → already in decimal
• B. 4.25 → already in decimal
• C. 10/3 = 3.33...
• D. 9/2 = 4.5

Compare all values:

• A: 4.4
• B: 4.25
• C: 3.33
• D: 4.5

Correct answer: D. 9/2 (which equals 4.5, the greatest value)

To find the area of the largest circle that can fit entirely inside a rectangle measuring 8 cm by 10 cm, we need to consider that:

• The largest possible circle that fits inside a rectangle is one where the diameter = the shorter side of the rectangle.

Step 1: Determine the diameter of the largest circle

The shorter side of the rectangle is 8 cm, so:

• Diameter = 8 cm
• Radius = 8 ÷ 2 = 4 cm

Step 2: Calculate the area of the circle

Area=πr2=π(4)2=16π cm2

Correct answer: A. 16π cm²

We are given:

• Daily charge: $23 per day
• Mileage charge: $0.42 per mile
• Rented for 3 days
• Driven 125 miles

Step 1: Calculate the daily rental cost

3days×23=69dollars

Step 2: Calculate the mileage cost

125miles×0.42=52.50dollars

Step 3: Total bill

69+52.50=121.50

Correct answer: C. $121.50

We are given:

• Each person drinks 3 boxes of juice
• 38 people at the picnic
• 6 boxes per package

Step 1: Total boxes needed

38people×3boxesperperson=114boxes

Step 2: Number of packages needed

114boxes/6boxesperpackage=19packages

Best estimate (rounding up to ensure enough juice):

20packages

Correct answer: A. 20 packages

We are asked to find the probability that a PN or an RN is a female.

Let’s break it down using the table:

Total staff:

• Male PN: 30
• Male RN: 50
• Female PN: 50
• Female RN: 70

Total staff = 30 + 50 + 50 + 70 = 200

Total female PNs and RNs:

• Female PN: 50
• Female RN: 70

Total females = 50 + 70 = 120

Now calculate the probability:

P(female)=1202/00=3/5P

Correct answer: A. 3/5

To find the average rate of change per year in the child’s height from birth to age 4, we use the formula:

AverageRateofChange =

=

= 22/4=5.5inchesperyear

Correct answer: A. 5.5 inches per year

We are given:

• Monthly income: $2,586.00
• Deductions:
  • Insurance: $517.20
  • Federal taxes: $299.33
  • Social security: $156.69
  • State taxes: $99.77

Step 1: Add all deductions

517.20+299.33+156.69+99.77=1,072.99

Step 2: Subtract from gross income

2,586.00−1,072.99=1,513.01

Correct answer: C. $1,513.01

An inverse relationship means that as one variable increases, the other decreases.

Let’s evaluate the options:

• A. As the number of credit hours increases, the cost per credit hour decreases.
  → This is an inverse relationship.
• B. As the number of credit hours decreases, the cost per credit hour decreases.
  → This is a direct relationship, not inverse.
• C. Cost remains the same regardless of credit hours.
  → This shows no relationship.
• D. Both increase together.
  → This is a direct relationship.

Correct answer: A.
