The expression \rm \frac{(j^{-3})(f^5)}{(c^2)(g^{-1})} is equivalent to the expression \frac{(f^5)(g^{1})}{(c^2)(j^{3})}. Then the correct option is B.

<h3>What is an equivalent expression?</h3>

The equivalent is the expressions that are in different forms but are equal to the same value.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The expression is given below.

\rm \rightarrow \dfrac{(j^{-3})(f^5)}{(c^2)(g^{-1})}

We know that a⁻¹ = 1/a and 1/a⁻¹ = a.

Simplify the expression. Then the expression will be

\rm \rightarrow \dfrac{(j^{-3})(f^5)}{(c^2)(g^{-1})}\\\\\\\rm \rightarrow \dfrac{(f^5)(g^{1})}{(c^2)(j^{3})}

The expression \rm \frac{(j^{-3})(f^5)}{(c^2)(g^{-1})} is equivalent to the expression \frac{(f^5)(g^{1})}{(c^2)(j^{3})}.

Then the correct option is B.

More about the equivalent link is given below.

Stardust the unicorn, covered a distance of 50 miles on his first trip to the forest. On a later trip he travelled 300 miles whi
jok3333 [9.3K]

His new time compared with the old time was increased by factor of 2

<h3>Further explanation</h3>

Acceleration is rate of change of velocity.

\large {\boxed {a = \frac{v - u}{t} } }

\large {\boxed {d = \frac{v + u}{2}~t } }

<em>a = acceleration (m / s²)v = final velocity (m / s)</em>

<em>u = initial velocity (m / s)</em>

<em>t = time taken (s)</em>

<em>d = distance (m)</em>

Let us now tackle the problem!

This problem is about Kinematics.

In this problem we assume that the unicorn is moving at a constant speed so that the acceleration is zero.

<u>Given:</u>

first distance = d₁ = 50 miles

second distance = d₂ = 300 miles

v₂ = 3 v₁

<u>Unknown:</u>

t₂ : t₁ = ?

<u>Solution:</u>

To find his new time , we will use the following formula.

v_2 = 3 v_1

\frac{d_2}{t_2} = 3 \times \frac{d_1}{t_1}

\frac{300}{t_2} = 3 \times \frac{50}{t_1}

\frac{300}{t_2} = \frac{150}{t_1}

t_2 = \frac{300}{150} \times t_1

\large {\boxed {t_2 = 2 \times t_1} }

Andy randomly selects an outfit to go to school. He can choose from 4 shirts: blue stripes, red stripes, black or white stripes.
denpristay [2]

Answer:

B and D

Step-by-step explanation:

The probability that Andy chooses a striped shirt and a pair of blue shorts is:

\frac{3}{4} * \frac{1}{3} = \frac{3}{12} = \frac{1}{4}

The probability that Andy chooses a striped shirt and pair of tan or plaid shorts is:

\frac{3}{4} * (\frac{1}{3} + \frac{1}{3}) = \frac{6}{12} = \frac{1}{2}

Which is an outlier out of 45,47,71,50,49 and 52
Elis [28]

The outlier is 71.

An outlier in a set of data is the one that is significantly lower or higher than the average of the totals. Whichever number skews the average is the outlier.

In this case, it's 71.

pishuonlain [190]

Answer:

So, we conclude that the best estimate for the difference in the proportion of smokers is 4.4%.

Step-by-step explanation:

We know that 27 of the 193 males in the sample smoke while 16 of the 169 females in the sample smoke.  

We have the following proportion:

27:x=193:100\%\\\\193x=27\cdot 100\\\\193x=2700\\\\x=\frac{2700}{193}\\\\x=13.9\%

So we get that 13.9% of men smoke.

We have the following proportion:

16:x=169:100\%\\\\169x=16\cdot 100\\\\169x=1600\\\\x=\frac{1600}{169}\\\\x=9.5\%

So we get that 9.5% of women smoke.

We get: 13.9%-9.5%=4.4%.

So, we conclude that the best estimate for the difference in the proportion of smokers is 4.4%.
