NEW QUESTION # 151
Which fraction is equal to 0.04?
Answer: D
Explanation:
This question tests your ability to convert between decimals and fractions, a very common skill on the NEX Math Section. Start by understanding the decimal value. The decimal 0.04 means four hundredths, which can be written as the fraction 4/100. The next step is to simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2. Doing so gives 2/50. That fraction exactly matches option C, making it the correct answer. To verify, you can also convert 2/50 back into a decimal by dividing 2 by 50, which equals 0.04. The other options are incorrect because they represent much larger values. For example, 1/4 equals 0.25, 2/5 equals 0.4, and 2/500 equals 0.004. On the NEX exam, remembering that two decimal places correspond to hundredths can help you quickly form the correct fraction before simplifying.

NEW QUESTION # 152
Five samples were taken of a population of four-year-old children.
The table shows the sample sizes and mean heights (cm):
Based on these samples, what is the mean height of the population of four-year-old children?
Answer: D
Explanation:
This question tests weighted averages. Because the sample sizes are different, you cannot simply average the mean heights. Instead, multiply each sample mean by its sample size, add the results, and divide by the total number of children.
Total children = 20 + 20 + 25 + 70 + 20 = 155
Total height = (20×95) + (20×100) + (25×100) + (70×110) + (20×105)
= 1,900 + 2,000 + 2,500 + 7,700 + 2,100
= 16,200
Mean height = 16,200 ÷ 155 # 104.5 cm
Therefore, option A is correct. The NEX exam frequently tests understanding that larger samples should carry more weight when calculating population estimates.

NEW QUESTION # 153
Reading Comprehension
Passage:
Sleep deprivation can impair immune function, making individuals more susceptible to illness. Over time, chronic lack of sleep may increase the risk of serious health conditions.
Which statement is best supported by the passage?
Answer: C
Explanation:
The passage states that lack of sleep weakens immune function and increases susceptibility to illness. This supports the conclusion that adequate sleep supports immune health. Option C accurately reflects this relationship. Options A and D contradict the passage, while option B exaggerates the effect. NEX questions often test the ability to infer logical conclusions without overgeneralizing.

NEW QUESTION # 154
A healthcare provider recommends that a patient take 200 milligrams (mg) of a pain reliever every 4 hours.
How many grams of the pain reliever should the patient have taken after 8 hours if the recommendation was followed?
(Given 1,000 mg = 1 gram.)
Answer: B
Explanation:
This is a medication dosage problem, a critical area on the NEX exam. First determine how many doses are taken in 8 hours. Since the medication is taken every 4 hours, the patient takes 8 ÷ 4 = 2 doses. Each dose is
200 mg, so the total amount taken is 200 × 2 = 400 mg. Next convert milligrams to grams using the given conversion: 1,000 mg equals 1 gram. Divide 400 ÷ 1,000 = 0.4 grams. Therefore, the correct answer is D.
Option B represents only one dose. Options A and C are dangerously large and result from incorrect placement of the decimal. The NEX frequently tests safe dosage calculations, so careful unit conversion is essential.
NEW QUESTION # 155
#3 # 7 =
Answer: B
Explanation:
This problem tests understanding of integer subtraction, especially with negative numbers. On the number line, #3 is already below zero. Subtracting 7 means moving seven more units to the left. Starting at #3 and moving left seven spaces results in #10. Another way to think about this is to rewrite the problem as adding a negative number: #3 # 7 is the same as #3 + (#7). When adding two negative numbers, you add their absolute values and keep the negative sign. The absolute values of #3 and #7 are 3 and 7, and 3 + 7 = 10, so the result is #10. Option A is therefore correct. Option B is a common mistake when students subtract absolute values incorrectly. Options C and D are positive and would only occur if the signs were misunderstood. The NEX Math Section frequently includes integer operations to assess number sense and sign awareness.
