3) practice/review a little everyday; it’ll help even if it’s 5 min a day.
4) ask friends/fam/teacher for help if you’re really having a hard time

Which of the following is an equivalent form of the compound inequality −33 > −3x − 6 ≥ −6?

djyliett [7]

Answer:

$-3x-6 < -33$ and $-3x-6 \geq -6$

Step-by-step explanation:

we have

$-33 > -3x-6 \geq -6$

we know that

Compound inequality can be divided into two inequalities

$-33 > -3x-6$

rewrite

$-3x-6 < -33$

and

$-3x-6 \geq -6$

therefore

An equivalent form of the compound inequality is

$-3x-6 < -33$ and $-3x-6 \geq -6$

Romashka-Z-Leto [24]

Answer:

$\= x = 82$

$s = 9.64$

Step-by-step explanation:

From the question we are told that

The data is 87 91 86 82 72 91 60 77 80 79 83 96

Generally the point estimate for the mean is mathematically represented as

$\= x = \frac{\sum x_i }{n}$

=> $\= x = \frac{87 +91 + 86 + \cdots + 96}{12}$

=> $\= x = 82$

Generally the point estimate for the standard deviation is mathematically represented as

$s = \sqrt{\frac{ \sum ( x_i - \= x )^2 }{ n -1 } }$

=> $s = \sqrt{\frac{ ( 87 - 82 )^2 +( 91 - 82 )^2 + \cdots + ( 96 - 82 )^2 }{ 12 -1 } }$

=> $s = 9.64$

Answer:

I am truly sorry if any of these answers are incorrect, I am here to help and I will do my best!

Step-by-step explanation:

A clock that uses hands to tell time is less precise than a clock that uses numbers.

A signal stored on a vinyl record is less easily copied than a signal stored in a computer.

A signal that is continuously varying is less reliable than a signal with limited possible values.

A signal transmitted by the human voice loses more energy as it travels than a signal transmitted by a fiberoptic cable.

Hope this helps! :)

If so, Brainliest would be nice... But it is ok if not :)

Find Horizontal and Vertical asymptotes for y=(x^2 -9)/(4x^2 +1)

Gnom [1K]

Answer: Horizontal asymptote is $\dfrac{1}{4}$ and vertical asymptotes are $\pm \dfrac{1}{2i}$

Step-by-step explanation:

Since we have given that

$y=\dfrac{x^2-9}{4x^2+1}$

We need to find the horizontal and vertical asymptotes.

Since vertical asymptotes will occur where the denominator becomes zero.

So, here denominator is $4x^2+1$

Now,

$4x^2+1=0\\\\4x^2=-1\\\\x^2=\dfrac{-1}{4}\\\\x=\pm \dfrac{1}{2i}$

And the horizontal asympototes will occur when the coefficient of higher degree of numerator is divided by coefficient of higher degree of denominator.

$y=\dfrac{1}{4}$

Hence, horizontal asymptote is $\dfrac{1}{4}$ and vertical asymptotes are $\pm \dfrac{1}{2i}$
