Heloo Mr. Don -u c that this a series of the type n^3,n+1^3,n+2^3....so the next two blanks are to be filled with the numbers 125 and 216...:)

Heloo ashu...the answer is v/4 bcoz :- let the first frequency be v1 and the second be v2.it is give that v2 is 25% of v1 i.e. V2

Solving 3 2/5 + 7 1/3 3 2/5 can be written as 17/5 and 7 1/3 can written as 22/3 So, adding 17/5 + 22/3 Multiply the denominator 5*3 will give as 15.. writing the two fractions where 15 is the denominator. 17/5*3/3 = 51/15 22/3*5/5 = 110/15 adding the two 51/15 + 110/15, will give us 161/15 or 10 11/15

if you do: x+2x=6 you get that x=2 and 2x=4 is the only possible combination of colors that fulfills "one of the colors appears twice as many times as the other",then you need to analyze: 2 BLUE & 4 WHITE (case 1) or 2 WHITE & 4 BLUE (case 2) We need to apply hypergeometric distribution here: p(k)=(K C k)(N−K C n−k)/(N C n) Where (I will put the numbers for case 1): K=Maximum number of successes (number of BLUE cards=8) k=number of expected successes (2 BLUE) N=Population size (13 cards=8 BLUE+5 WHITE) n=number of draws(6). Then you have for the first case:. p1(k=2)=(8 C 2)(5 C 4)/ (13 C 6)=0.0815 case "2 WHITE+4 BLUE" P(k2=2) = 0.4079 It is case 1 or case 2, then the total probability is 0.0815+0.4079=0.4895, that is a 48.95%

I hav qstion i need answer.. If the numerator of a fractionis multiplied by 4 and the denominatoris reduced by 2,the result is 2.if the numeratorof the fraction is increase by 15 and 2 subtracted from thedouble of the denominator the result is 9/7, find the fraction

I wanna solve...

a rectangle of board measures 21 m by 70 cm. Circular plates are to be cut from the board of diameter 14 cm. how many plates and board is left

1500/45×X/120 =X×45=1500×120 45x=1500×120 X=1500×120/45 X=180000/45 X=4000 Ans=4000 newspapers in 2hrs
