Answer:

See below

Step-by-step explanation:

$x=-3 \\\\x^{-2}= 3^{-2}=\dfrac{1}{3^2}=\dfrac{1}{9} \\\\x^{-1}= 3^{-1}=\dfrac{1}{3^1}=\dfrac{1}{3} \\\\x^0=3^0=1 \\\\x^1=3^1=3 \\\\x^2=3^2=9$

Tresset [83]

Answer:

2.49

Step-by-step explanation:

Given X= 58

N = 175.

P = 25% = 0.25.

$P' = \frac{X}{N} = \frac{58}{175} = 0.3314\\Z = \frac{P'-P}{\sqrt{\frac{pq}{N} } }$

Now plugging the values we get

$= \frac{0.3314-0.25}{\sqrt{\frac{0.25\times0.75}{175} } }$

=2.49

lys-0071 [83]

By definition, the area of a circle is given by:
$A = \pi * r ^ 2
$
Where,
r: radius of the circle.
Substituting the values in the given expression, we have:
$A = 3.14 * (3) ^ 2

 A = 28.26 feet ^ 2$
Rounding to the nearest tenth we have:
$A=28.3feet^2$
Answer:
Approximately needed:
$A=28.3feet^2$
