Bihar STET Paper 1 Mathematics Mock Test - 7 - Bihar PGT/TGT/PRT MCQ

 Central tendency is the central value for a probability distribution. Mean,media,mode and range are the measures of central tendeny. Amongst them, median can be determined graphically.

clearly first term is 4/3
for common difference 1/3-4/3=-1

When 245 and 1029 are divided by the required number then there is left 5 as remainder. It means that 245 - 5 = 240 and 1029 - 5 = 1024 will be completely divisible by the required number.
Now we determine the HCF of 240 and 1024 by Euclid's Algorithm.
1024 = 240 x 4 + 64
240 = 64 x 3 + 48
64 = 48 x 1 + 16
48 = 16 x 3 + 0
Since remainder comes zero with last divisor 16,
required number = 16

⇒ x² + 3x + 1 = x² - 4x + 4

⇒ 7x - 3 = 0 ,

it is not of the form ax² + 6x + c = 0

So, A is incorrect but R is correct.

The altitudes of a triangle are the line segments drawn from each side of the triangle to the angle opposite that side, such that the line segment is perpendicular to the side it is drawn from. In an isosceles triangle, only the altitudes of the legs of equal length in the triangle are congruent. 

⇒ p(x) = x²−3x−10
But we know that, if we multiply or divide any polynomial by any arbitrary constant. Then, the zeroes of the polynomial never change.
Therefore,

p(x)=kx²−3kx−10

 Where,k is a real number

Hence, the required number of polynomials having zeros −2 and 5 are infinite i.e. more than 3.

Let ABCD is a square circumscribing a circle of radius a cm.
The side of square ABCD = Diameter of circle
⇒AB=2a
Therefore, perimeter of square AB=4×AB=4×2a=8 cm

Clarification: The graph of the polynomial 2x²-8x+5 cuts the y-axis.
Hence, the value of x will be 0.
y(0)=2(0)²-8(0)+5
y=5
The graph cuts the y-axis at (0,5)

3p + 6p + 8p + 13p = 30p = 360° ⇒ p

= 12° Largest angle is 13p = 13 × 12°

= 156°

3 cot θ = 2 ⇒ cot θ = 2/3 ⇒ tan θ = 3/2 

Common difference=¼-0=½-¼=¼
Next term =¾+¼=1
Next term =1+¼=5/4

Thus, it can be expressed as product of linear factors.

Special schools are schools that cater to children with special needs. Students with special needs can be classified into five categories-

• Physical impairment
• Visual impairment
• Hearing and speech impairment
• Low mental ability
• Learning disability 

Key Points

The backward child is also called a slow learner. The child is unable to cope with routine work normally expected of his/her age group. The rate of learning is the basis for identifying slow learners. Special schools are required for backward children when Backwardness is due to any serious physical handicap. He finds it difficult to keep pace with the normal child in his school work. The characteristics of backward learners are as given below: 

1. They have limited cognitive capacity.
2. For them rational thinking is impossible.
3. They have the capacity for rote learning and can retain memory whatever is learned only with a lot of practice and revision in comparison with the normal child.
4. They have poor memory.
5. They are distractive and lack concentration in the classroom.
6. They have an Inability to express through language. The slow learner has cognitive problems, language-related problems, auditory perceptual problems, visual-motor problems, and social-emotional problems.

Note:  Lower achievers don't come under students with special needs.

From the above, we can say that special schools are required for backward children when backwardness is due to any serious physical handicap as special schools are for students with special needs.

The main aim of CCE is to evaluate every aspect of the child during their presence at the school. This is believed to help reduce the pressure on the child during/before examinations as the student has to sit for multiple tests throughout the year, of which no test or the syllabus covered is repeated at the end of the year, whatsoever. The CCE method is claimed to bring enormous changes from the traditional chalk and talk method of teaching, provided it is implemented accurately. As a part of this new system, student's marks have been replaced by grades which are evaluated through a series of curricular and extra-curricular evaluations along with academics. The aim is to reduce the workload on students and to improve the overall skill and ability of the students by means of evaluation of other activities.

Essay type questions do not provide scope to assess the students objectively. Mrs. Suman is using essay type questions. These questions are subjective in nature and their answers vary from subject to subject; whereas multiple choice questions, true/false type questions, or one word answer type questions are used to assess the students objectively.

The National Mission on Foundational Literacy and Numeracy in NEP 2020 aims to enhance early literacy and numeracy skills.

Assessment of learning refers to the process of evaluating a student's knowledge, skills, and understanding of a subject or topic. The primary goal of the assessment of learning is to determine the level of achievement of learning outcomes and provide feedback to both students and teachers. 

Some games, like some real situations, are intensely competitive, where an individual or a team has to compete against someone else. In case of a team, cooperation among members is of paramount importance to reach the objective or to deal with any issue effectively, So, both these skills are required to excel in different real life situations. A teacher must know what would bring out the best in the students and ensure the same.

Continuous Comprehensive Evaluation is a school-based evaluation system. It promotes orderly learning and development. It includes regularity in assessment, diagnosis of learning gaps, retesting, etc. So, CCE emphasizes how learning can be observed, recorded, and improved upon. It is a 'continuous' process after each course over the entire session. 'Comprehensive' means the scheme follows both scholastic and co-scholastic aspects of students.
Hence, the correct answer is, 'How learning can be observed, recorded and improved upon.'

Google has partnered with the Election Commission of India (ECI) to provide authoritative information on voting processes for the upcoming general elections. Through Google Search and YouTube videos, voters can access critical details on registration, voting, and candidate information, aiding in informed decision-making.

Peru has declared a health emergency in response to the surge in dengue fever cases, with over 31,000 reported cases and 32 fatalities in 2024. This declaration encompasses 20 out of Peru's 25 regions, highlighting the severity of the situation in the country.

∠DAC = ∠B + ∠C
(Exterior angle prop. of a Δ ABC)
According to question,
130° = 2A + 3A
5A = 130°
A = 26°
∴ ∠B = 52°; ∠C = 78°

10 men = 20 women
Man : Woman = 2 : 1

Hence, Option B is correct.

Hence, the person will be allowed to write a written test.
