Question 15: Marcus earns $12 per hour plus a $25 bonus per day. Which equation shows his daily earnings E for h hours worked?

E = 25(h + 12)
E = 25h + 12
E = 12(h + 25)

{(1,2),(1,3),(2,4)}
x = 4
{(2,5),(3,5),(4,5)} (Correct answer)

8.5 ft (Correct answer)
8 ft
7 ft
7.5 ft

Correct answer: 8.5 ft

The man's height, his shadow, and the line from the top of his head to the end of his shadow form a right-angled triangle. We can use the Pythagorean theorem (a² + b² = c²) to find the length of the hypotenuse, which represents the length of his shadow from top to bottom. Plugging in the values, 5.8² + 6.2² = c², which calculates to 33.64 + 38.44 = 72.08. Taking the square root of 72.08 gives approximately 8.49 feet, which rounds to 8.5 feet.

Question 86: Keeping Tropical Fish Keeping tropical fish at home or in your office used to be very popular. Today, interest has declined, but it remains as rewarding and relaxing a hobby as ever. Ask any tropical fish hobbyist, and you will hear how soothing and relaxing watching colorful fish live their lives in the aquarium. If you are considering keeping tropical fish as pets, here is a list of the basic equipment you will need. A filter is essential for keeping your aquarium clean and your fish alive and healthy. There are different types and sizes of filters and the right size for you depends on the size of the aquarium and the level of stocking. Generally, you need a filter with a 3 to 5 times turnover rate per hour. This means that the water in the tank should go through the filter about 3 to 5 times per hour. Most tropical fish do well in water temperatures ranging between 240 C and 260 C, though each has its own ideal water temperature. A heater with a thermostat is necessary to regulate the water temperature. Some heaters are submersible and others are not, so check carefully before you buy. Lights are also necessary and come in a large variety of types, strengths, and sizes. A light source is necessary for plants in the tank to photosynthesize and give the tank a more attractive appearance. Even if you plan to use plastic plants, the fish still require light, although here you can use a lower-strength light source. A hood is necessary to keep dust, dirt, and unwanted materials out of the tank. Sometimes the hood can also help prevent evaporation. Another requirement is aquarium gravel. This will improve the aesthetics of the aquarium and is necessary if you plan to have real plants. What proof does the author offer to back up their assertion that aquarium lights are required?

Plants require light.
Aquarium lights make the aquarium more attractive.
The author does not provide evidence for this statement.
Fish and plants require light. (Correct answer)

Correct answer: Fish and plants require light.

The author provides two main reasons for the necessity of aquarium lights. First, they state, 'A light source is necessary for plants in the tank to photosynthesize.' Second, they add, 'Even if you plan to use plastic plants, the fish still require light.' Therefore, the author asserts that both fish and plants require light as proof of its necessity.

Question 87: In California High School Proficiency Exam test preparation, what is the best approach to estimation problems?

Always calculate exact answers
Round to manageable numbers and calculate approximate answers (Correct answer)
Skip estimation entirely
Use only mental math

95
91 (Correct answer)

93

Correct answer: 91

Target total = 85 × 5 = 425; current total = 334; 425 − 334 = 91.

Question 91: A triangle has angles measuring 45° and 75°. What is the measure of the third angle?

50°
55°
60° (Correct answer)
80°

Correct answer: 60°

The angles of a triangle sum to 180°, so 180 − 45 − 75 = 60°.

Question 92: Which sentence is written in passive voice?

An elaborate meal was prepared by the chef. (Correct answer)
The chef prepares elaborate meals every night.
The chef prepared an elaborate meal.
The chef has been preparing an elaborate meal.

Passive voice occurs when the subject receives the action rather than performs it; 'an elaborate meal' receives the action of being prepared.

Question 93: Identify the sentence with correct pronoun-antecedent agreement.

Each student must bring their own pencil.
Someone left their jacket in the room.
Everyone finished their test on time.
The team celebrated its championship win. (Correct answer)

'Team' is treated as a singular collective noun here, so 'its' correctly agrees with it.

Question 94: Which word best replaces 'said' to show that a character spoke angrily?

Whispered
Snapped (Correct answer)
Murmured

'Snapped' conveys speaking in a sharp, irritated manner, indicating anger.

64 cm²
16 cm²
48 cm²
96 cm² (Correct answer)

Correct answer: 96 cm²

Question 97: A square has a diagonal of length 10 cm. What is the side length?

7.07 cm
10√2 cm
5√2 cm (Correct answer)
5 cm

Correct answer: 5√2 cm

For a square with side s, diagonal = s√2, so s = 10 / √2 = 5√2 ≈ 7.07 cm.

Question 98: Which sentence contains a misplaced modifier?

Maria, walking to school, saw a rainbow.
Maria saw a rainbow walking to school. (Correct answer)
Walking to school, Maria saw a rainbow.

'Oblique' means not direct or straightforward; it refers to something that is slanting or diverging from a straight line or course.

IQR = 15; outlier below 0 or above 50
IQR = 15; outlier below 5 or above 57.5 (Correct answer)
IQR = 15; outlier below −2.5 or above 57.5
IQR = 55; outlier above 90

Correct answer: IQR = 15; outlier below 5 or above 57.5

IQR = 35 − 20 = 15; outlier boundaries are Q1 − 1.5×IQR = 20 − 22.5 = −2.5 and Q3 + 1.5×IQR = 35 + 22.5 = 57.5.

Circumference = π × d = 3.14 × 10 = 31.4 cm.

Question 131: A passage argues that teenagers who work part-time during school earn better grades because they learn time management. A reader who thinks critically would first ask:

Does working cause better grades, or do motivated students do both? (Correct answer)
How old are the teenagers in the study?
What kinds of jobs do teenagers work?
What state do the teenagers live in?

Correct answer: Does working cause better grades, or do motivated students do both?

Critical readers question whether correlation implies causation—motivated students may both work and earn good grades without one causing the other.

Question 132: The perimeter of a regular pentagon is 45 cm. What is the length of one side?

5 cm
11 cm
9 cm (Correct answer)

9.42 cm (Correct answer)
4.71 cm
18.84 cm

CHSPE (California High School Proficiency) Exam

The California High School Proficiency Examination (CHSPE) was administered by the California Department of Education for students seeking early high school completion. The exam had a 3.5-hour time limit and covered two sections: English-Language Arts (84 multiple-choice reading questions + essay) and Mathematics (50 multiple-choice questions). A scaled passing score of 350 out of 450 was required on each section. Note: The CHSPE was replaced by the California Proficiency Program (CPP)/HiSET in 2023; this content reflects historical CHSPE format.
