Step-by-step explanation:

\bf a)~2\cdot2^{-3} =  2^{1-3} =2^{-2}=\dfrac{1}{2^{2}} =\blue{\dfrac{1}{4}}

\bf b)~~\bigg(\dfrac{1}{4}\bigg)^{-2} \cdot 4=  4^{2} \cdot 4=4^{1+2}=4^{3}=\purple{64}

\bf c)~~\dfrac{\big(3^{-2}\big)^{3}\cdot 27^{2}}{3} =\dfrac{3^{-2\cdot3}\cdot (3^{3})^{2}}{3}=

\bf \dfrac{3^{-6}\cdot 3^{3\cdot2}}{3}=\dfrac{3^{-6}\cdot 3^{6}}{3}=  \dfrac{\dfrac{1}{\not3^{6}}\cdot \not3^{6}}{3}=\red{\dfrac{1}{3}}

Response Question
Paha777 [63]

Answer:

The right solution is "3.29, 3.57".

Step-by-step explanation:

Seems that the given problem is incomplete. Below is the attachment of the complete and appropriate query.

<u>The given values are</u>:

Randomly selected adults,

n = 105

Mean,

\bar{x} = 3.42

Standard deviation,

s = 0.75

Now,

At 95% confidence level if given by,

=  \bar{x} \ \pm \ Z_{\frac{\alpha}{2} }\times \frac{s}{\sqrt{n} }

On putting the given values, we get

=  3.42 \ \pm \ Z_{\frac{0.05}{2} }\times \frac{0.75}{\sqrt{105} }

=  3.42 \ \pm \ 1.96\times 0.073

=  3.42 \ \pm \ 0.143

=  3.29, 3.57

abio and Carlos play on a basketball team together. In the last game, Fabio had 777 points less than 222 times as many points as
tankabanditka [31]

Answer:

The equation 31=2c-7 to determine the number of points Carlos scored in the last game.

Step-by-step explanation:

We are given with,(I think every number is repeating for 3 times. So, I took each number as once)

Fabio had 7 less than 2 times as many points as Carlos. And Fabio score 31 points.

Let Carlos scored in the last game as "C".

So, we can set up equation for Fabio had 7 less than 2 times Carlos as

Fabio= 2C-7

Like so for Fabio score 31 as

Fabio =31

So, substitute Fabio as 31 into the first equation, we get

31= 2c-7

So, the equation 31=2c-7 to determine the number of points Carlos scored in the last game.
