Answer:

<h2>D. 61% of the respondents were restaurant owners.</h2>

Step-by-step explanation:

If we read the problem, we can realize that the report is about eating out, about food, so the variables is towards that context. Among the options, D is the only one that relates to food, because it's about restaurant owners. Other options are not useful in this report, because they are about something else.

Basically, being Democrats, more than 6 feet tall or at certain age, all those variable are not relate with eating out. Therefore, the correct answer is D.

84. Use properties of exponents to rewrite each expression with only positive, rational exponents. Then find the numerical value
Yakvenalex [24]

Answer:

a) 1/27

b) 16

c) 1/8

Step-by-step explanation:

a) x^{-3/2}

One of the properties of the exponents tells us that when we have a negative exponent we can express it in terms of its positive exponent by turning it into the denominator (and changing its sign), so we would have:

x^{-3/2}=\frac{1}{x^{3/2} }

And now, solving for x = 9 we have:

\frac{1}{x^{3/2}}=\frac{1}{9^{3/2} }  =\frac{1}{27}

b) y^{4/3}

This is already a positive rational exponent so we are just going to substitute the value of y = 8 into the expression

y^{4/3}=8^{4/3}=16

c) z^{-3/4}

Using the same property we used in a) we have:

z^{-3/4}=\frac{1}{z^{3/4} }

And now, solving for z = 16 we have:

\frac{1}{z^3/4} } =\frac{1}{16^{3/4} } =\frac{1}{8}
