A student performs the following estimations. 24+190≈210 151+319≈470 974+1022≈1990 Based on these estimations, which of the following is the student’s estimate of 452+5017?

A. 5470

B. 5500

C. 5400

D. 5450

Answer Explanation:

from the given estimations, we can find the actual addition of the numbers and see a trend the student utilizes to find their estimates. The exact sum is as follows

24+190=214

151+319=470

974+1022=1996

From the above evaluation, we can clearly see the students approximates the value in the ones values. So, in the problem we need to approximate 452+5017.

452+5017=5469

We can approximate 5469 based on the provided choices to 5470.

Therefore, the Correct Answer is A.

Q #1: As a person cycling increases speed, the rate of calories burned, distance traveled, and energy expended also increase. Which of the following is the independent variable?

A. Energy

B. Calories

C. Speed

D. Distance

Answer Explanation

an independent variable is one that when changed, causes the other variable(s) to change. In our case, calories burned, distance traveled, energy used increase when cycling speed increases.

Therefore, speed is the independent variable while other variables are dependent.
Q #2: The data below represents students’ test scores. Which of the following is the median of the set data? 11, 12, 18, 14, 22, 17, 17, 12, 26, 12, 13

A. 15

B. 12

C. 14

D. 15.8

Answer Explanation

the median of a data set is the element that is found on the middle position. It is found by organizing the elements from the smallest to largest.

The data set above arranged from the smallest to largest is:

11, 12, 12, 12, 13, 14, 17, 17, 18, 22, 26

The number of elements is odd and the median is found in the (N+1)/2 th position. Here N=11, and the median falls in (11+1)/2=12/2=6 th position.

The element 14 falls in the 6th position, which is our median of the given data set.
Q #3: The graph below represents the amount of rainfall in a particular state by month. Which of the following is the total rainfall for the first 3 months of the year?  

A. 4 inches

B. 5 inches

C. 4.5 inches

D. 3.5 inches

Answer Explanation

The first three months of the year are January, February, and March. We need to find the total rainfall for these three months from the provided graph.

In the month of January, rainfall is between o and 1, which is halfway. Therefore, rainfall in January is 0.5 inches

On February, rainfall was 1 inch and on March the rainfall was 2 inches. Thus,

Total rainfall = 0.5 inches + 1 inches + 2 inches = 3.5 inches
