According to the table above, which of the following is the relationship between the slices of a cake and number of calories?

Slices of cake	0	2	5	11	19
Calories	0	960	2,400	5,280	9,120

We are told:

• 3.2 inches of tape is needed per inch of diameter
• The tube has a diameter of 5 inches

Step: Multiply

3.2×5=16 inchesoftape

Correct answer: A. 16 inches

We’re given:

• F = 41°
• Formula: C=5/9(F−32)/

Now substitute:

C=5/9(41−32) =5/9(9) =5

Correct answer: C. 5°

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

We're told the relationship is proportional and that the point (7, 157.5) lies on the line, meaning:

7 hours → $157.50

To find the hourly rate, divide total earnings by hours:

157.5/7=22.5

So, the employee earns $22.50 per hour.

Correct answer: D. Manaf earns $22.50 per hour

Let's briefly rule out the others:

• A. 22.5 hours is not mentioned in the original data.
• B. $7/hour is incorrect.
• C. $157.50/hour is incorrect (it's the total, not the rate).

We're told the ordered pair (3, 24) lies on the line representing the relationship between:

• x = number of lunches,
• y = total cost in dollars.

So, (3, 24) means:

When 3 lunches are ordered, the total cost is $24.

Correct answer: C. 3 lunches cost a total of $24

Let’s quickly rule out the others:

• A. Says each lunch is $24 — wrong.
• B. Reverses the values.
• D. Says 24 lunches cost $3 each — not related to (3, 24).

We are given:

• Bill = $43.20
• Gratuity = 15%

Step 1: Calculate 15% of $43.20

0.15×43.20=6.48

Step 2: Add the gratuity to the bill

43.20+6.48=49.68

Correct answer: D. $49.68

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

To find the percent of the population that is left-handed, use the data from the table:

Left-Handed:

• Male: 3
• Female: 4
• Total left-handed = 3 + 4 = 7

Total population:

• Male: 3 + 29 = 32
• Female: 4 + 34 = 38
• Total population = 32 + 38 = 70

Percent left-handed:

7/70×100=10%

Correct answer: D. 10%

To find the mean of the data, add all the values and divide by the number of values.

Given values:

• 1.34
• 0.18
• 2.1
• 0.77
• 1.41

Step 1: Sum the values

1.34+0.18+2.1+0.77+1.41=5.8

Step 2: Divide by the number of values

There are 5 values:

5.8/5=1.16

Correct answer: C. 1.16

The dependent variable is the one that depends on or is determined by other variables.

In this case:

• Price is determined by the model, mileage, and age

Correct answer: A. Price

Because it depends on the other factors listed.
