<u><em>Answer:</em></u>
The factored form is: (x-2)(x-4) = 0

<u><em>Explanation:</em></u>
To factor an expression, we need to <u>get its solutions</u>.

<u>The standard form of the quadratic equation is:</u>
ax² + bx + c = 0

<u>The given equation is:</u>
x² - 6x + 8 = 0

<u>By comparison:</u>
a = 1
b = -6
c = 8

Now, to get the roots, we will substitute with the values of a, b and c in the quadratic formula shown in the attached image.

<u>This will give us:</u>
either x = \frac{6+ \sqrt{(-6)^2-4(1)(8)} }{2(1)} = 4
This means that the first factor is (x-4)

or x = \frac{6- \sqrt{(-6)^2-4(1)(8)} }{2(1)} = 2
This means that the second factor is (x-2)

Based on the above, the factored form would be:
(x-4)(x-2) = 0

Hope this helps :)

Answer:

(x-2)(x-4)

Step-by-step explanation:

x^2 -6x +8

We need to find numbers that add to -6 but multiply  8. We know that 4 and 2 multiply to 8 but they do not add to -6. -4 and -2 add to -6 and -4 times -2 equal 8. Therefore the factored form of x^2 -6x + 8 is (x-2)(x-4).

Hope this helps:))) Hva e a good day

The average temperature in Fairbanks, Alaska, was —4°F one day and
Oksanka [162]

Answer:

  • 20°

Step-by-step explanation:

<u>We know that:</u>

  • -4 + x = 16 [x = difference between two temperatures]

<u>Solution:</u>

  • -4 + x = 16
  • => x = 16 + 4
  • => x = 20

Hence, the difference between the two temperatures is 20°.

I think it would be y plus 3 times 2 equals 5x. I'm not sure if that is what they are asking for.

A clinical trial tests a method designed to increase the probability of conceiving a girl. In the study 340 babies were​ born, a
Bas_tet [7]

Answer:

The 99% confidence interval estimate of the percentage of girls born is (0.8, 0.9).

b)Yes, the proportion of girls is significantly different from 0.5.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence interval 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

Z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

In the study 340 babies were​ born, and 289 of them were girls. This means that n = 340, \pi = \frac{289}{340} = 0.85

Use the sample data to construct a 99​% confidence interval estimate of the percentage of girls born.

So \alpha = 0.01, z is the value of Z that has a pvalue of 1 - \frac{0.01}{2} = 0.995, so z = 2.575.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{340}} = 0.85 - 2.575\sqrt{\frac{0.85*0.15}{400}} = 0.80

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{340}} = 0.85 + 2.575\sqrt{\frac{0.85*0.15}{400}} = 0.90

The 99% confidence interval estimate of the percentage of girls born is (0.8, 0.9).

Does the method appear to be ​effective?

b)Yes, the proportion of girls is significantly different from 0.5.
