What is the Empireal equation? |
| Answer» Empirical probability is an objective probability. It is also known as relative frequency\xa0or experimental probability.By definition, Empirical Probability is the number of outcomes in which a specified event occurs to the total number of trials.Empirical probability is different from Theoretical probability on certain major aspects. That is, in theoretical probability, the probability is measured on the basis of the likeliness of an outcome. Whereas in the case of Empirical probability, the probability\xa0is based on how the event actually occurred during trials. The formula for Empirical probability is unlike a\xa0theoretical probability formula.P(E)= Number of times event occurs / Total number of times experiment performed\xa0 | |

X+y=102x-2y=2Solve the equation by cross multiplication method |
| Answer» x+y=10=>x+y-10=0..2x-2y=2=>x-y-1=0..From cross multiplication,x÷(1×(-1)-(-1)(-10)=y÷(-10×1-(-1)(1)=1÷(1(-1)-1(1).=>x÷(-11)=y÷(-9)=1÷(-2)A/q. -x/11=-1/2=>x/11=1/2=>x=11/2.and -y/9=-1/2=>y=9/2 | |

3x/2- 5y/3= -2, x/3+y/2=13/6 solve it by the substitution method ( pls help me).. |
|
Answer» ❤️❤️ use this emoji Thanks rashi and don\'t use this brokenheart word pls♥️??????? Thaks pranali ????❤️? Thanks pranali ?? 3x /2-5y/ 3= -2 ,.On taking LCM and simplification, we get9x - 10y = -12 ....(1 )On simplification, 2x + 3y = 13 ......... (2)Multiply the (1) by 3 and the equation (2) by 1027x - 30y = -3620x + 30y = 130Adding both equations, we get47x = 94x = 2Substitute x = 2 in equation (2) 2(2) + 3y = 133y = 9y = 34. |

The product of consecutive positiv integer is 306.we need to find the integer. |
|
Answer» Let the consecutive no. be x and (x+1) then,A/q, x(x+1)=306 => x²+x-306 => x²-17x+18x-306 => x(x-17)+18(x-17) => (x-17)(x+18) => x=17 or -18 Let two consecutive numbers are x and (x + 1) A/C to question,product of x and (x + 1) = 306 ⇒x(x + 1) = 306 ⇒x² + x - 306 = 0⇒ x² + 18x - 17x - 306 = 0⇒x(x + 18) - 17(x + 18) = 0⇒(x + 18)(x - 17) = 0⇒ x = 17 and -18Hence, numbers are x = 17 and (x +1) = 18 |
