|
Answer» We know that 8 pencils + 16 erasers are equal to 68 rupees Now we will divide it by 4 And then 2 pencils + 4 erasers are equal to 17 rupees Now we will find the cost of 3 pens And for that we will use this formula Cost of 3 pens + 17 is equal to 92 rupees Cost of 3 pens is equal to 75 rupees Cost of 1 pen is equal to 25 rupees Now in order to find the price of 24 pens 25 x 24 = 600 So the final answer for this question is 600 |

A die is thrown twice. What is the prohability that () 5 will not come up either time (i) 5 will comeup at least once? |
|
Answer» dice will thrown twice so total 36 ppsaibilitynow probability of 5 will not comeso we have to eliminate (5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(1,5),(2,5),(3,5),(4,5),(6,5)so probability=25/36now 5 at least 1 time so probability=11/36 |

IZ+1ZSo panove thal the pointC1o |

Answer» it forms the general equation of circle let z = x+iy , then z+1 = (x+1)+iy and z-1 = (x-1)+iy so |z+1| = √[(x+1)²+y²] and |z-1| = √[(x-1)²+y²] now squaring both sides..we get (x+1)²+y² = 2*[(x-1)²-y²] = 2(x-1)²+2y²=> y²-2y² = 2x²+2-4x-x²-2x-1=> x²+y²-6x+1 = 0=> y² + x²-2*(x)*(3) +3³-3³ +1 = 0=> y² +(x-3)²-8 = 0so, y² +(x-3)² = 8... represents a circle.

Write at least two questions to find the mean, giving suitable data |
| Answer» | |

\operatorname { sin } ( A + B ) = 1 \text { and } \operatorname { cos } ( A - B ) = 1,0 ^ { \circ } \leq ( A + B ) \leq 90 ^ { \circ } \text { and } A > B |
|
Answer» Sin(a+b)=1 ——-[1]. Cos(a-b)=1———-[2] From 1 &2 Sin(a+b)=cos (a-b) Sin (a+b)= sin (90-a+b) Sin gets cancelled on both sides a+b=90-a+b 2a=90 a=45 since a and b are complementary to each other a+ b=90 B=90-45=45 |
