Question 1 of 5
A couple dining at a restaurant receives a bill for $38.40. They wish to leave a 15% gratuity. What is the estimated gratuity amount?
Correct Answer: A
Rationale: To calculate the 15% gratuity on a $38.40 bill, you multiply the bill amount by 0.15 (15%): $38.40 x 0.15 = $5.76. Since gratuity amounts are typically rounded up, the estimated gratuity would be $6.00, making choice A the correct answer. In this case, rounding up to the nearest whole dollar is common practice in gratuity calculations to simplify tipping and ensure a fair amount for the service provided.

Question 2 of 5
When the weights of newborn babies are graphed, the distribution of weights is symmetric with the majority of weights centered around a single peak. Which of the following describes the shape of this distribution?
Correct Answer: D
Rationale: The described distribution, where the majority of weights are centered around a single peak and symmetric, is referred to as bell-shaped. In a bell-shaped distribution, the data is symmetric around the mean, with most values clustering near the peak and tapering off towards the extremes. This pattern is commonly seen in normal distributions, such as the distribution of birth weights in newborns. The bell-shaped curve represents a typical symmetric distribution, indicating that most newborn weights fall close to the average weight with fewer extreme values. Therefore, the correct answer is 'Bell-shaped'.
Question 3 of 5
How many milliliters are in 0.5 liters?
Correct Answer: C
Rationale: To convert liters to milliliters, you need to know that 1 liter is equal to 1,000 milliliters. Therefore, to find out how many milliliters are in 0.5 liters, you multiply 0.5 by 1,000, which gives you 500 milliliters. Hence, the correct answer is 500 milliliters. Remember, when converting between units, you must use the correct conversion factor to ensure the accuracy of your calculations.
Question 4 of 5
2.50 � 0.25 Simplify the expression above. Which of the following is correct?
Correct Answer: D
Rationale: Multiplying 2.50 by 0.25 gives 0.625.
