Question 2 of 10
2. Question
Do the physical properties change when volume changes but the mass are held constant?
Correct
Density is defined as mass over volume, so if the mass is held constant and volume is changed, the density will also change. It gets larger when the volume is decreased and smaller when the volume is increased.
Incorrect
Density is defined as mass over volume, so if the mass is held constant and volume is changed, the density will also change. It gets larger when the volume is decreased and smaller when the volume is increased.

Question 3 of 10
3. Question
Which of the following numbers have the highest value?
Correct
Compare each numeral after the decimal point to figure out which overall number is greatest. In answers A (1.43785) and C (1.43592), both have the same tenths (4) and hundredths (3). However, the thousandths are greater in answer A (7), so A has the greatest value overall.

Question 4 of 10
4. Question
What is the value of b in this equation?
7b – 4 = 2b + 16Correct
To solve for the value of b, both sides of the equation need to be equalized.
Start by cancelling out the lower value of 4 by adding 4 to both sides:
7b – 4 = 2b + 16
7b – 4 + 4 = 2b + 16 + 4
7b = 2b + 20
7b – 2b = 20
5b =20
b=20/5
b=4Incorrect
To solve for the value of b, both sides of the equation need to be equalized.
Start by cancelling out the lower value of 4 by adding 4 to both sides:
7b – 4 = 2b + 16
7b – 4 + 4 = 2b + 16 + 4
7b = 2b + 20
7b – 2b = 20
5b =20
b=20/5
b=4

5. Question
A student gets a 75% on a test with 20 questions. How many answers did the student solve correctly?
Correct

Question 6 of 10
6. Question
What is the overall median of Jac’s 78, 92, 83, 97?
Correct
For an even number of total values, the median is calculated by finding the mean or average of the two middle values once all values have been arranged in ascending order from least to greatest. In this case, would equal the median 87.5.
Incorrect
For an even number of total values, the median is calculated by finding the mean or average of the two middle values once all values have been arranged in ascending order from least to greatest. In this case, would equal the median 87.5.

Question 8 of 10
8. Question
What cellular organelle is used to digest food for recycling?
Correct
The cell structure responsible for cellular storage, digestion and waste removal is the lysosome. Lysosomes are like recycle bins. They are filled with digestive enzymes that facilitate catabolic reactions to regenerate monomers.

Question 9 of 10
9. Question
If the pressure in the arteries rises above normal, which heart chamber will be affected first?
Correct
Any increase in pressure in the artery will eventually affect the contractibility of the right ventricle. Blood enters the right atrium from the superior and inferior vena cava veins, and blood leaves the right atrium through the tricuspid valve to the right ventricle.
