The numbers are irrational, so they can't be written exactly.
Rounded to the nearest thousandth, they are

11.196
and
0.804 .

11.196 + 0.804 = 12
11.196 x 0.804 = 9.002...

BaLLatris [955]

<h2>Answer with explanation:</h2>

Let p be the population proportion of parents who had children in grades K-12 were satisfied with the quality of education the students receive.

Given : Several years ago, 39% of parents who had children in grades K-12 were satisfied with the quality of education the students receive.

Set hypothesis to test :

$H_0: p=0.39\\\\H_a :p\neq0.39$

Sample size : n= 1055

Sample proportion : $\hat{p}=\dfrac{466}{1055}=0.441706161137\approx0.44$

Critical value for 95% confidence : $z_{\alpha/2}=1.96$

Confidence interval : $\hat{p}\pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}$

$0.44\pm (1.96)\sqrt{\dfrac{0.39(1-0.39)}{1055}}\\\\0.44\pm0.0299536805135\\\\0.44\pm0.03\\\\=(0.44-0.03, 0.44+0.03)\\\\=(0.41,\ 0.47)$

Since , Confidence interval does not contain 0.39.

It means we reject the null hypothesis.

We conclude that 95% confidence interval represents evidence that parents' attitudes toward the quality of education have changed.

HELPPPPPPPPPPPPP and please don't put the "link" i really need answers!!!

Answer:

The first option is

A(x) = 10000(1.05)ˣ

The second option is:

B(0) = 1000
B(1) = 1100
The ratio is 1.1 and the zero term is 1000

The equation for this option is:

B(x) = 1000(1.1)ˣ

Now, which option is better?

It depends on the number of x. It is assumed the genie is offering money or similar reward.

For the values of x below 50 option A is better and option B is much better for x > 50.

See the graph in the attachment, where green line represents the option A and red line is option B.
