Answer:

  • n = 10

Step-by-step explanation:

  • 4^8/(4^2)^-3 ÷ 4^4 = 4^n
  • 4^8/4^-6 ÷ 4^4 = 4^n
  • 4^(8 - (-6) - 4) = 4^n
  • 4^10 = 4^n
  • 10 = n
  • n = 10

To Find :

  • value of n

<h2>Solution :</h2>

\sf \dashrightarrow \:  \frac{4 {}^{8} }{(4 {}^{2} {)}^{ - 3}  }  \div  {4}^{4}  = 4 {}^{n}  \\  \\ \sf \dashrightarrow \:  \frac{4 {}^{8} }{ {4}^{ - 6} }  \div  {4}^{4}  = 4 {}^{n}  \\  \\ \sf \dashrightarrow \:  {4}^{8 - ( - 6)}  \div  {4}^{4}  =  {4}^{n}  \\  \\ \sf \dashrightarrow \:  {4}^{8 + 6} \div  {4}^{4}  =  {4}^{n}  \\  \\ \sf \dashrightarrow \: {4}^{14}  \div  {4}^{4}  =  {4}^{n}  \\  \\ \sf \dashrightarrow \: {4}^{14 - 4}  =  {4}^{n}  \\  \\ \sf \dashrightarrow \: {4}^{10}  = 4 {}^{n}  \\  \\   \red{\boxed{ \bf \: n = 10}}

Simplify g^1/2 * g^1/2 using the radical form.
guapka [62]

Answer:

√g *√g = g

Step-by-step explanation:

recall that any number or variable to the power of 1/2 can also be written as that variable or number under the radical.

So, we then have

√g * √g

Recall that when we multiply radicals, we multiply what is under our radicals together and then combine them under a new radical

√g * √g = √(g * g)

This gives us √(g²)

recall that the square root of a number or variable squared will merely result in the number or variable by itself (as these are reciprocate equations)

√(g²) = g

Reading proficiency: An educator wants to construct a 99.5% confidence interval for the proportion of elementary school children
Shkiper50 [21]

Answer:

A sample size of 345 is needed so that the confidence interval will have a margin of error of 0.07

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 level of 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}.

The margin of error of the interval is given by:

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

In this problem, we have that:

p = 0.69

99.5% confidence level

So \alpha = 0.005, z is the value of Z that has a pvalue of 1 - \frac{0.005}{2} = 0.9975, so Z = 2.81.

Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.07?

This is n when M = 0.07. So

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

0.07 = 2.81\sqrt{\frac{0.69*0.31}{n}}

0.07\sqrt{n} = 1.2996

\sqrt{n} = \frac{1.2996}{0.07}

\sqrt{n} = 18.5658

(\sqrt{n})^{2} = (18.5658)^{2}

n = 345

A sample size of 345 is needed so that the confidence interval will have a margin of error of 0.07

I need some help with this question
yarga [219]

Answer:

-7/15

Step-by-step explanation:

-4/5 translates to -12/15 and 1/3 translates to 5/15.

When you add -12/15+5/15 you get

-12+5/15 so you get -7/15
