Answer:

The equivalent expression will be 1,215 Superscript one-fifth x

Step-by-step explanation:

The given expression is Root Index 5 Start Root 1,215 End Root Superscript x i.e. (\sqrt[5]{1215} )^{x} and we have to find the equivalent expression from options.

Now, (\sqrt[5]{1215} )^{x} can be written as (1215)^{\frac{x}{5} }.

Since we know that \sqrt[n]{x} can be written using the properties of exponent as x^{\frac{1}{n}}

So, the equivalent expression will be 1,215 Superscript one-fifth x i.e. (1215)^{\frac{x}{5} }. (Answer)

H0 : the treatment has no effect

against the claim

FinnZ [79.3K]

Answer:

a + b ≥ 40

a + 5 ≤ b

2.50a + 1.50b ≤ 105

Step-by-step explanation:

We are told she would like to have at least 40 cupcakes and cookies combined.

If a is number of cupcakes and b is number of cookies, then this inequality is;

a + b ≥ 40

Secondly, we are told she would like to have at most 5 more cupcakes than cookies.

Thus, the inequality is;

a + 5 ≤ b

Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50

Thus, the inequality is;

2.50a + 1.50b ≤ 105

Finally, the 3 inequalities are;

a + b ≥ 40

a + 5 ≤ b

2.50a + 1.50b ≤ 105
