Fill in the blanks when a die thrown the, the probability of getting a number less then 7 is.... |
|
Answer» Answer: 1 Step-by-step EXPLANATION: Given that, A die is thrown. To find the Probability. We KNOW that, Probability is the ratio of the number of favourable outcomes to the total possible Outcomes. Here, when a die is thrown. Possible Outcomes = 1, 2, 3, 4, 5, 6 Therefore, we get, No. of possible outcomes = 6 Now, to find the Probability that the number comes is less than 7. We have favourable Outcomes = 1,2,3,4,5,6 Therefore,we get, No. of favourable outcomes = 6 Therefore, we will get, => Probability=6/6 = 1 Hence, required probability is 1. |

Find the S.D of first 21 natural number |
|
Answer» Answer: The standard deviation of first 21 NATURAL number is √36.66 Step-by-step Explanation: We know that б = √ [Σxi²/n - (Σxi/n)²] Σxi = [n * (n + 1)] / 2 .........(i) Σxi² = [n * (n + 1) * (2n + 1)] / 6 .........(II) here, n = 21 now we have to put the value of n in EQUATION (i) and (ii) Σxi = ( 21 * 22 ) / 2 = 231 Σxi² = ( 21 * 22 * 43 ) / 6 = 3311 now , б = √ [ (3311 / 21) - (231/21)² ] б = √ [ 157.66 - 11² ] б = √ [ 157.66 - 121 ] = √36.66 So the standard deviation of first 21 natural number is √36.66. ---------------------------------------------------------------------- Hope it helps U and please follow me, I will be thankful to u...

Answer» Answer: Step-by-step explanation: In multiplication of surds we will learn how to find the product of two or more surds. Follow the following steps to find the multiplication of two or more surds. Step I: Express each surd in its simplest MIXED form. Step II: OBSERVE WHETHER the given surds are of the same order or not. Step III: If they are of the same order then the required product is obtained by multiplying the product of the RATIONAL co-efficient by the product of surd-factors. If they are of different orders then the product is obtained by the above method after reducing them to surds of the same order. If different order surds have the same base then their product can easily be obtained using the laws of indices. |

If x-1/x=5, find the value of x4+ 1/x4 |
|
Answer» Answer: 727 Step-by-step explanation: ⇒ X - 1 / x = 5 Square on both sides: ⇒ ( x - 1 / x )^2 = 5^2 USING ( a - B )^2 = a^2 + b^2 - 2ab ⇒ ( x )^2 + ( 1 / x )^2 - 2( x * 1 / x ) = 25 ⇒ x^2 + 1 / x^2 - 2( 1 ) = 25 ⇒ x^2 + x^2 = 25 + 2 ⇒ x^2 + 1 / x^2 = 27 Again, square on both sides: ⇒ ( x² + 1 / x² )² = 27² ⇒ x⁴ + 1 / x⁴ + 2( x² * 1 / x² ) = 729 ⇒ x⁴ + 1 / x⁴ + 2 = 729 ⇒ x⁴ + 1 / x⁴ = 729 - 2 ⇒ x⁴ + 1 / x⁴ = 727 |

Answer» Answer: - 4√5 or 3√5 Step-by-step explanation: Using Splitting middle term which says split the middle( with x ) in two parts such that their product is the product of constant term and term with x^2. Here, we found a satisfying PAIR is 4√5 - 3√5 ⇒ x^2 + √5 x - 60 = 0 ⇒ x^2 +( 4√5 - 3√5 )x - 60 = 0 ⇒ x^2 + 4√5 x - 3√5 x - 60 = 0 ⇒ x( x + 4√5 ) - 3√5( x + 4√5 ) = 0 ⇒ ( x + 4√5 )( x - 3√5 ) = 0 ⇒ x = - 4√5 or x = 3√5

4) A father’s age is three times the sum of the ages of his two children. After 5 years, his age will be two times the sum of their ages. Find the present age of father. |
Answer» ANSWER :Let the AGE of the sons be x and y. Given that Father’s age is three times the age of his two sons. Therefore, present age of father is 3(x+y) Now, it is also given, after 5 YEARS, his age will be twice the sum of the ages of his son. Therfore, after 5 years age of father will be 3(x+y)+5 and age of the sons will be x+5 and y+5. 3(x+y)+5 = 2(x+5+y+5) 3x+3y+5 = 2x+10+2y+10 3x+3y+5 = 2x+2y+20 3x-2x+3y-2y = 20–5 x+y = 15 Now the age of father was 3(x+y)=3(15)=45 (PUTTING the value of x+y) Thus the age of the father is 45.
