Answers:

1a: I can predict that Flower Garden and Butterlfies and Ladybugs are the two more likely to be chosen, over April Showers.

1b: These percentages I got can prove my theory of that the probability of choosing April Flowers is much lower than the two other options.

Flower Garden: 35/78 ≈ 45%

April Showers: 16/78 ≈ 21%

Butterflies and Ladybugs: 27/78 ≈ 34%

2a: What you should NOT do is conclude which two will be picked.

2b: Although you can predict, based on percentages or other things. You cannot make such a conclusion with the choice being random.

Which statement describes if there is an extraneous solution to the equation √x-3 = x-5? A. there are no solutions to the equati

Brrunno [24]

Remember that an extraneous solution of an equation, is the solution that emerges from solving the equation but is not a valid solution.

Lets solve our equation to find out what is the extraneous solution:
 $\sqrt{x-3} =x-5$
$(\sqrt{x-3})^2 =(x-5)^2$
$x-3=x^2-10x+25$
$x^2-11x+28=0$
$(x-4)(x-7)=0$
$x-4=0$ and $x-7=0$
$x=4$ and $x=7$

So, the solutions of our equation are $x=4$ and $x=7$ . Lets replace each solution in our original equation to check if they are valid solutions:
- For $x=7$
$\sqrt{x-3} =x-5$
$\sqrt{7-3} =7-5$
$\sqrt{4} =2$
$2=2$
We can conclude that 7 is a valid solution of the equation.

- For $x=4$
$\sqrt{x-3} =x-5$
$\sqrt{4-3} =4-5$
$\sqrt{1} =1$
$1 \neq 1$
We can conclude that 4 is not a valid solution of the equation; therefore, 4 is a extraneous solution.

We can conclude that the correct answer is: D. the extraneous solution is x = 4

If 2500 amounted to 3500 in 4 years as simple interest .find the rates at wish the interest was charged

Bad White [126]

Answer:

The interest rate per year is 0.1

Step-by-step explanation:

The equation is A = P(1+rt)

Substitute the numbers

3500 = 2500 (1+4r)

solve for r:

$3500/2500 = 1+4r$
