RMA Reviewer Post Test

Practice flashcards covering key concepts and questions from the RMA Reviewer Post Test notes.

What verification can be made for the expression 4 × 4 - 5 × 3?

It computes to 16 - 15 = 1, thus verifying the classmate's claim.

What is the next number expression after 5 × 5 - 6 × 4 in Box 1?

6 × 6 - 7 × 5.

Which algebraic expression best represents the set of number expressions in Box 1?

The correct option is (b) (n)(n)-[(n + 1)(n − 1)].

What does n represent in the chosen expression from item 3 if option b is selected?

n is the first number in the numerical expression.

Show that 1024 is a power of 2 according to Table 1.

1024 = 2^10, hence it is a power of 2.

What is the exponential form of 1024?

2^10.

Find a multiple of 16 that is between 50 and 200.

64 or 128.

Is there a number between 0.998 and 0.999? Provide an example.

Yes, for example, 0.99801.

How do you subtract 0.998 from 0.999?

0.999 - 0.998 = 0.001.

What is an example of a fraction that is greater than 0 but less than 1?

For example, 4/5.

How many students had an overall academic grade below 84 in the graph?

5 students.

What justifies that there are five points with y-coordinates below 84?

There are five points below the horizontal line at 84.

Interpret the graph's data regarding student absences and overall academic grades.

As the number of absences increases, the overall academic grade decreases.

Which purok shows more diversity in monthly family income according to Figure 2?

Purok 1 shows more diversity.

What explains the greater diversity in Purok 1's income?

The range of income in Purok 1 (32) is greater than that of Purok 2 (9).

How many students participated in the music activity according to Table 2?

49 students.

What is the probability of selecting a student who participated in both activities?

The probability is 18/110 or 0.163636.

What is the position of point F in Figure 3?

Point F is at -300.

What are the coordinates of Point C in Figure 4?

(4, 4).

Which ordered pairs represent points on the line drawn through points B and C?

Any of the combinations: b & d, b & f, d & f.

What is the method to find the area of triangle ABC from points A, B, and C in Figure 4?

Using the formula A = 1/2 bh results in 12 sq units.

In the triangular dog house, what are the lengths of the other two sides according to Figure 7?

The other two sides are 1.5 meters each.

Are the sides of the triangular dog house proportional to the triangular toy storage?

Yes, they are proportional by AA Similarity Theorem.

What is the area of the sidewalk around the pool in square meters?

The area of the sidewalk is 34.54 sq. m.

What is the total volume of water in the pool with given depths according to Figure 9?

Total volume can be represented as the sum of volumes for adult and children's sections.

How far did the wheel travel after 5 rolls according to Figure 10?

942 cm or 9.42 m.

How many degrees did the wheel's pin rotate after 5 rolls?

1800 degrees.

Explain or show why you think you have chosen the correct algebraic expressions for the set of number expression in Box 1

(n)(n)- [(n+1)(n-1)]= n² + (n²-1) = n² - n² + 1 = 1

What is the position of G

0

Which of the following can be a correct interpretation of the data presented in the graph in Figure 1?

c. As the number of absences increases, the overall academic grade decreases.

Based on the graph in Figure 2, which of the two puroks shows more diversity in monthly family income? Explain or justify your answer.

Purok 1 shows more diversity because it has a greater range of income (40 − 8 = 32) compared to Purok 2 (24 − 15 = 9). This means the incomes in Purok 1 are more spread out.

. The average monthly income of the families in Purok 1 and Purok 2 are equal. Should both purok be given the same amount of financial aid? What information in the graph in Figure 2 did you base your decision on?

No. Even if the averages are equal, Purok 1 has greater variability in income. The graph shows that Purok 1 has both the lowest and highest incomes, meaning income is less evenly distributed. Financial aid should be based on families with lower income rather than giving the same amount to both puroks.
