8 is the answer

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

[tex]z=2^{3}[/tex]

This question is essentially asking what is two to the third power, or;

[tex]2 * 2 * 2[/tex]

[tex]= 8[/tex]

Answer: 1 5/7

Step-by-step explanation:

First lets simplify 2/5x1/4,

-> 8/20x5/20

-> 40/20

-> 4/2

Now lets calculate:

42÷−7−6=?

In the second fraction, the negative numerator and negative denominator cancel each other.

The equivalent equation is

42÷76=?

Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.

Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes

42×67=?

For fraction multiplication, multiply the numerators and then multiply the denominators to get

4×62×7=2414

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 14 using

GCF(24,14) = 2

24÷214÷2=127

The fraction

127

is the same as

12÷7

Convert to a mixed number using

long division for 12 ÷ 7 = 1R5, so

127=157

Therefore:

42÷−7−6=157

Solution by Formulas

Apply the fractions formula for division, to

42÷−7−6

and solve

4×−62×−7

=−24−14

A negative over a negative becomes positive

=2414

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(24,14) = 2

24÷214÷2=127

Convert to a mixed number using

long division for 12 ÷ 7 = 1R5, so

127=157

Therefore:

42÷−7−6=1 5/7

(Sorry for the 157s I meant 1 5/7)

Answer:

negative

35

Step-by-step explanation:

find the greatest common factor and multiply those 2 then divide whats left and then reduce or simplify and multiply those again

Answer:

Try your best! I know you can do it!

Answer:

a) The minimum sample size is 601.

b) The minimum sample size is 2401.

Step-by-step explanation:

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

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

For this problem, we have that:

We dont know the true proportion, so we use [tex]\pi = 0.5[/tex], which is when we are are going to need the largest sample size.

95% confidence level

So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

a. If a 95% confidence interval with a margin of error of no more than 0.04 is desired, give a close estimate of the minimum sample size that will guarantee that the desired margin of error is achieved. (Remember to round up any result, if necessary.)

This is n for which M = 0.04. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.04 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.04\sqrt{n} = 1.96*0.5[/tex]

[tex]\sqrt{n} = \frac{1.96*0.5}{0.04}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.04})^2[/tex]

[tex]n = 600.25[/tex]

Rounding up

The minimum sample size is 601.

b. If a 95% confidence interval with a margin of error of no more than 0.02 is desired, give a close estimate of the minimum sample size necessary to achieve the desired margin of error.

Now we want n for which M = 0.02. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.02 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.02\sqrt{n} = 1.96*0.5[/tex]

[tex]\sqrt{n} = \frac{1.96*0.5}{0.02}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.02})^2[/tex]

[tex]n = 2401[/tex]

The minimum sample size is 2401.

Step-by-step explanation:  54/6=9

-6-6-6-6-6-6-6-6-6=-54

Given:

The polynomial is

[tex]p(x)=x^3-2x^2+2x[/tex]

To find:

The real and complex zeros of the equation.

Solution:

We have,

[tex]p(x)=x^3-2x^2+2x[/tex]

For zeros, p(x)=0.

[tex]x^3-2x^2+2x=0[/tex]

[tex]x(x^2-2x+2)=0[/tex]

[tex]x(x^2-2x+2)=0[/tex]

[tex]x=0\text{ and }x^2-2x+2=0[/tex]

The real value of x is 0. The equation [tex]x^2-2x+2=0[/tex] will give complex roots. Here, a=1, b=-2 and c=2.

Using quadratic formula, we get

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]x=\dfrac{-(-2)\pm \sqrt{(-2)^2-4(1)(2)}}{2(1)}[/tex]

[tex]x=\dfrac{2\pm \sqrt{4-8}}{2}[/tex]

[tex]x=\dfrac{2\pm \sqrt{-4}}{2}[/tex]

On further simplification, we get

[tex]x=\dfrac{2\pm \sqrt{-1}\sqrt{4}}{2}[/tex]

[tex]x=\dfrac{2\pm 2i}{2}[/tex]

[tex]x=\dfrac{2(1\pm i)}{2}[/tex]

[tex]x=1\pm i[/tex]

Therefore, the real zero is 0 and the complex zeros are 1+i and 1-i.

Answer:

Step-by-step explanation:

Use the power rule for differentiation

[tex]f'(x)=nx^n^-^1[/tex]

[tex]f'(x)=(4\frac{d}{dx} 2x^2^-^1)-(8\frac{d}{dx} 1x^1^-^1)+\frac{d}{dx}2[/tex]

[tex]f'(x) =8x-8[/tex]

The derivative of a constant is always zero
