When individuals in a sample of 150 were asked whether or not they supported capital punishment, the following information was o

Roman55 [17]

Answer:

Option C.

Step-by-step explanation:

Given information:

Sample size = 150

Number of Opinions = 3 (Yes, No, No Opinion)

Yes = 40

No = 60

No opinion = 50

We need to find the expected frequency for each group.

Expected frequency for each group is the quotient of sample size and number of opinions.

$\text{Expected frequency for each group}=\dfrac{\text{Sample size}}{\text{Number of Opinions}}$

$\text{Expected frequency for each group}=\dfrac{150}{3}$

$\text{Expected frequency for each group}=50$

Therefore, the correct option is C.

Which choice is equivalent to the product below when x > 0?

anastassius [24]

The product below is equivalent when x > 0 is <u>1/9</u>

<h3>Resolution - Explanation</h3>

Square root is a real number x multiplied by itself - which results in a perfect value, where it is possible to calculate the real proof (which is the square root).

Given the expression, $\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$ , first step: we will calculate the root of the numerator and denominator of this fraction:

<u />

<u /> $\\\large \sf \sqrt{\dfrac{1}{x^{2} } } \cdot \sqrt{\dfrac{x^{2} }{81} }$

$\large \sf \dfrac{\sqrt{1} }{\sqrt{x^{2} } } \rightarrow \dfrac{1}{x}$

$\large \sf \dfrac{\sqrt{x^{2} } }{\sqrt{81 } } \rightarrow \dfrac{x}{9}\\\\$

Step two: rearranging the expression and canceling the common factors x, we will have,:

$\\\large \sf \dfrac{1}{\not x} \cdot \dfrac{\not x}{9}$

$\pink{\boxed{\large \sf \dfrac{1}{9} }}\\$

Therefore, the final answer to this multiplication will be 1/9.
