How many terms are there in the AP 41,38,35,...,8? |
|
Answer» An= a + (n-1)dwhere, a= 41 and d = a2 -a1=38-41=-3now, 8 = 41 + (n-1)-38-41=-3n+3-33 = -3n+3-33-3 =-3n-36=-3nn =12Answer: 12 terms. An= a + (n-1)dwhere, a= 41 and d = a2 -a1=38-41=-3now, 8 = 41 + (n-1)-38-41=-3n+3-33 = -3n+3-33-3 =-3n-36=-3nn =12therefore there are 12 terms. |

Find the 20th term from the last term of the ap:3, 8,13.........,253 |
|
Answer» Given AP is 3,8,13........253 first term a=3 an=253 common difference =5According to Question Let d=-5 a=253 an=3 n=20a+(n-1)d =an =>253 +(n-1)-5 =3=>(n-1)-5=-230 =>(n-1)=-250 /-5=>n-1=50=>n=50+1=>n=51 Given series is 3, 8, 13, ...... 253here, first term , a = 3common difference , d = 5Let us find total number of terms at first.use\xa0=> 253 = 3 + (n - 1)5=> 250 = 5(n - 1)=> n - 1 = 50=> n = 51so, there are 51 terms in given series.now we know, mth term from last =last term - mth term + 1so, 20th term from last = 51 - 20 + 1 = 32hence, 20th from last = 32th term from firstuse ,\xa0T32= a+(32 -1)d= 3 + 31 × 5 = 3 + 155 = 158hence , 20th term from last = 158\xa0 |

What is the meaning of quadratic equations |
| Answer» A\xa0quadratic\xa0equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero. | |

How many three digit numbers are divisible by seven |
|
Answer» The first 3-digit number which is divisible by 7 is 105The last 3-digit number which is divisible by 7 is 994The list of 3-digit numbers divisible by 7 are105, 112, 119,…..994 which forms an A.PNow using the A. P Formula,T(n) = a + (n – 1)dWherea = 105d = 7T(n) = 994994 = 105 + (n – 1)7889 = 7n – 77n = 896n = 128∴ There are 128 3-digits number which are divisible by 7. 128 H |

What is the fundamental theorem of arithmetic with example |
| Answer» Fundamental Theorem of Arithmetic:Fundamental Theorem of Arithmetic states that every composite number greater than 1 can be expressed or factorised as a unique product of prime numbers except in the order of the prime factors.We can write the prime factorisation of a number in the form of powers of its prime factors.By expressing any two numbers as their prime factors, their highest common factor (HCF) and lowest common multiple (LCM) can be easily calculated.The HCF of two numbers is equal to the product of the terms containing the least powers of common prime factors of the two numbers.The LCM of two numbers is equal to the product of the terms containing the greatest powers of all prime factors of the two numbers. | |

what is equally likely outcomes |
|
Answer» For many experiements it is reasonable to assume that all possible outcomes are equally likely.For example:\tDraw a random sample of size n from a population. The assumption that the sample is drawn at random means that all samples of size n have an equal chance of being chosen (much of statistical analysis depends on the assumption that samples are chosen randomly).\tFlip a fair coin n times and observe the sequence of heads and tails that results.\tRoll n dice, die 1, die 2, die 3, . . . , die n, and observe the ordered sequence of numbers on the uppermost faces. The outcomes of a sample space are called equally likely if all of them have the same chance of occurring |

Prove that 3 is irrational |
| Answer» Let us assume that √3 is a rational number.then, as we know a rational number should be in the form of p/qwhere p and q are co- prime number.So,√3 = p/q { where p and q are co- prime}√3q = pNow, by squaring both the sidewe get,(√3q)² = p²3q² = p² ........ ( i )So,if 3 is the factor of p²then, 3 is also a factor of p ..... ( ii )=> Let p = 3m { where m is any integer }squaring both sidesp² = (3m)²p² = 9m²putting the value of p² in equation ( i )3q² = p²3q² = 9m²q² = 3m²So,if 3 is factor of q²then, 3 is also factor of qSince3 is factor of p & q bothSo, our assumption that p & q are co- prime is wronghence,. √3 is an irrational number | |
