Which expressions are equal to 6^3•2^6/ 2^3

Mathematics
1 answer:
True [87]3 years ago
3 0

Answer:

2^6 x 3^3 and 12^3

Step-by-step explanation:

First, solve

6^3 x 2^6/2^3

216 x 64/8

13824/8 = 1728

lets solve for the answers

6^3 = 216

Therefore, 6^3 is not an answer

2^6 x 3^3= 64 x 27 = 1728

because both expressions are equal to 1728, this is an answer. this answer can also eliminate 2^3 x 3^3 because it has a lower exponent than the answer that is equal to 1728. therefore, the value of it must be smaller than 1728

12^3 = 1728

This answer is correct, because both values are equal to each other, meaning that 12^6 is larger than 1728  

Therefore, your answers will be 2^6 x 3^3 and 12^3

Suppose that the mean time that visitors stay at a museum is 94.2 minutes with a standard deviation of 15.5 minutes. The standar
Maurinko [17]

Answer:

94.2 -0.994*3.1 = 91.1186

94.2 +0.994*3.1 = 97.2814

And the 68% confidence interval is given by (91.1186, 97.2814)

Step-by-step explanation:

For this case we know that mean time that visitors stay at a museum is given by:

\bar X = 94.2

The standard deviation is given by:

s= 15.5

And the standard error is given by:

SE = \frac{s}{\sqrt{n}} =3.1

And we want to interval captures 68% of the means for random samples of 25 scores and for this case the critical value can be founded like this using the normal standard distribution or excel:

z_{\alpha/2}= \pm 0.994

We can find the interval like this:

\bar X \pm ME

And replacing we got:

94.2 -0.994*3.1 = 91.1186

94.2 +0.994*3.1 = 97.2814

And the 68% confidence interval is given by (91.1186, 97.2814)

Answer:

a=14

b=6

c=5

Step-by-step explanation:

x-6\sqrt{x}  + 4 = 0

x +4 =6\sqrt{x}

x^2 + 8x + 16 = 36x

x^2 - 28x + 16 = 0

14 ±6\sqrt{5}

Tina is the top seller of the store. She earns a salary plus 2%. Tina's salary is $30,000 a year. This month her sales were $48,
Lilit [14]
I'm assuming she gets 2% commission on sales and that she gets paid monthly from her yearly salary.

If the above is true, her monthly pay is calculated as follows:

Commission: 48500 * 0.02 = $970
Monthly salary: 30000 ÷ 12 = $2500

So monthly pay is $2500 + $970 = $3470
