Which shows the unsimplified solution for x2 + 8x + 6 = 0?

Answers

Answer 1

Answer: $x^2 + 8x + 6 = 0 \n \n x^2 + 8x + 16 + 6 -16 =0\n \nx^2 + 8x + 16 -10=0\n \nx^2 + 8x + 16=10\n \n (x + 4)^2 = 10\n \nx + 4 = √( 10 ) \ \ or \ \ x + 4 = - √(10) \n \nx = √(10)-4 \ \ or \ \ x = -4 - √(10 )$

A set of face cards contains 4 Jacks, 4 Queens, and 4 Kings. Carlie chooses a card from the set, records the type of card, and then replaces the card. She repeats this procedure a total of 60 times. Her results are shown in the table.How does the experimental probability of choosing a Queen compare with the theoretical probability of choosing a Queen?

The experimental probability is 4 less than the theoretical probability.
The experimental probability is 1/15 less than the theoretical probability.
The experimental probability is 1/15 more than the theoretical probability.

Answers

The experimental probability is 1/15 less than the theoretical probability.

Given

A set of face cards contains 4 Jacks, 4 Queens, and 4 Kings.

Carlie chooses a card from the set, records the type of card, and then replaces the card.

She repeats this procedure a total of 60 times. Her results are shown in the table.

What is experimental probability?

Theoretical probability describes how likely an event is to occur.

The theoretical probability of choosing a Queen is;

$\rm Theoretical\ probability= (Observed \ frequency)/(Probability \ of \ selecting \ Queen)\n\n Theoretical\ probability= (16)/(4)\n\n Theoretical\ probability= (4)/(1)$

What is experimental probability?

Experimental probability describes how frequently an event actually occurred in an experiment.

The experimental probability of choosing a Queen is;

$\rm Experimental \ probability = Relative \ frequency\n\nExperimental \ probability = (4)/(15)$

For comparing the theoretical and experimental probability of both equations.

$\rm =(Experimental \ probability)/(Theoretical \ probability)\n\n= ((4)/(15))/((4)/(1))\n\n= (4)/(15)* (1)/(4)\n\n= (1)/(15)$

Hence, the experimental probability is 1/15 less than the theoretical probability.
