Answer:

5:15; 5 cups of juice and 15 cups of lemonade

Step-by-step explanation:

when simplified, the ratio is 1:3; so the first number multiplied by 3 equals the 2nd number

other answers: 6:18, 7:21, 8:24

Answer:

Step-by-step explanation:

each ratio can be reduced to 1/3

1/3 = 2/6 = 3/9 = 4/12 = 5/15 = 6/18 = 7/21 = 8/24 = 9/27 = 10/30 ...

Megan:
x to the one third power = $x ^{1/3}$
<span>x to the one twelfth power = </span> $x ^{1/12}$

<span>The quantity of x to the one third power, over x to the one twelfth power is:
</span> $\frac{x ^{1/3}}{x ^{1/12}}$
<span>
Since </span> $\frac{ x^{a} }{ x^{b} } = x ^{a-b}$
then $\frac{x ^{1/3}}{x ^{1/12}} = x^{1/3-1/12}$

Now, just subtract exponents:
1/3 - 1/12 = 4/12 - 1/12 = 3/12 = 1/4

$\frac{x ^{1/3}}{x ^{1/12}} = x^{1/3-1/12} = x^{1/4}$

Julie:
x times x to the second times x to the fifth = x * x² * x⁵

<span>The thirty second root of the quantity of x times x to the second times x to the fifth is
</span> $\sqrt[32]{x* x^{2} * x^{5} }$
<span>
Since </span> $x^{a}* x^{b}= x^{a+b}$
Then $\sqrt[32]{x* x^{2} * x^{5} }= \sqrt[32]{ x^{1+2+5} } =\sqrt[32]{ x^{8} }$

Since $\sqrt[n]{x^{m}} = x^{m/n} }$
Then $\sqrt[32]{ x^{8} }= x^{8/32} = x^{1/4}$

Since both Megan and Julie got the same result, it can be concluded that their expressions are equivalent.

Answer:

13) $(5x)^{-\frac{5}{4}$ ⇒ $\frac{1}{\sqrt[4]{(5x)^5}}$

15) $(10n)^{\frac{3}{2}$ ⇒ $\sqrt{(10n)^3}$

Step-by-step explanation:

Given expression:

13) $(5x)^{-\frac{5}{4}$

15) $(10n)^{\frac{3}{2}$

Write the expressions in radical form.

Solution:

For an expression with exponents as fraction like

$(x)^{\frac{m}{n}$

the numerator $m$ represents the power it is raised to and the denominator $n$ represents the nth root of the expression.

For an expression with exponents as negative fraction like

$(x)^{-\frac{m}{n}$

We take the reciprocal of the term by rule for negative exponents.

So it is written as:

$\frac{1}{(x)^{\frac{m}{n}}}$

using the above properties we can write the given expressions in radical form.

13) $(5x)^{-\frac{5}{4}$

⇒ $\frac{1}{(5x)^{\frac{5}{4}}}$ [Using rule of negative exponents]

⇒ $\frac{1}{\sqrt[4]{(5x)^5}}$ [writing in radical form]

15) $(10n)^{\frac{3}{2}$

⇒ $\sqrt{(10n)^3}$ [Since 2nd root is given as $\sqrt{}$ in radical form]

The scores of a high school entrance exam are approximately normally distributed with a given mean mu = 82.4 and standard deviat

Slav-nsk [51]

The percentage of the scores that are between 75.8 and 89 is; 95%

<h3>How to find the percentage from z-score?</h3>

We are given;

Population mean; μ

Standard deviation; σ = 3.3

Thus;

z-score for a mean score of 75.8 is;

z = (75.8 - 82.4)/3.3

z = -2

z-score for a mean score of 89 is;

z = (89 - 82.4)/3.3

z = 2

From online p-value from z-score calculator, the p-value between both z-scores is;

p-value = 0.9545 = 95.45%

Approximating to the nearest percent = 95%
