In the market for labor, demand describes

A sporting goods store is having a large sale event. Baseball bats are marked down by 42%, and hockey sticks are marked down by

Rina8888 [55]

The correct statement is "Hockey sticks had their prices reduced by $0. 41 more than baseball bats."

Mark down refers to a reduction in price of an item or good. The reduction is generally done as a percentage of price of the item. The purpose behind mark down is to increase sales volume.

<h3>Calculation of reduction in price:</h3>

Given:

Markdown in price of baseball bats is 42%

Cost of baseball bats after markdown is $21.46

Markdown in price of hockey sticks is 29%

Cost of hockey sticks after markdown is $39.05

For calculating the amount of markdown, we need to find the original cost of baseball bats and hockey sticks.

Calculation of cost of baseball bats before markdown:

$\begin{aligned} \rm Cost \:before\:markdown &= \dfrac{\rm Cost \:after \:Markdown}{100- \rm Markdown\%} \\
\\
&=\dfrac{21.46}{100-42\%}\\
\\
&=\dfrac{21.46}{58\%}\\
\\
&=\$37\end$

Hence the markdown in price of baseball bats is $\$37-\$21.46=\$15.54$

Similarly, for hockey sticks:

$\begin{aligned} \rm Cost \:before\:markdown &= \dfrac{\rm Cost \:after \:Markdown}{100- \rm Markdown\%} \\\\&=\dfrac{39.05}{100-29\%}\\\\&=\dfrac{39.05}{71\%}\\\\&=\$55\end$

Markdown in the cost of hockey sticks is $\$55-\$39.05=\$15.95$ .

Difference in markdown is:

$\$15.95-\$15.54=\$0.41$

Therefore it can be concluded that markdown in cost of hockey sticks is more as compared to baseball bats by $0.41

Hence the correct statement is "Hockey sticks had their prices reduced by $0. 41 more than baseball bats."

Let $S$ be the set of complex numbers of the form $a + bi,$ where $a$ and $b$ are integers. We say that $z \in S$ is a unit if t

lakkis [162]

Answer:

Number of units possible in S are 4.

Explanation:

Given <em>S</em> is a set of complex number of the form $a+bi$ where <em>a</em> and <em>b</em> are integers.

$z\in S$ is a unit if $w\in z$ exists such that $zw=1$ .

To find:

Number of units possible = ?

Solution:

Given that:

$zw = 1$

Taking modulus both sides:

$|zw| = |1|$

Using the property that modulus of product of two complex numbers is equal to their individual modulus multiplied.

i.e.

$|z_1z_2|=|z_1|.|z_2|$

So,

$|zw| = |1|\\\Rightarrow |zw| =|z|.|w| =1\\\Rightarrow |z|=\dfrac{1}{|w|}$ ......... (1)

Let $z=a+bi$

Then modulus of z is $|z| = \sqrt{a^2+b^2}$

Given that a and b are <em>integers</em>, so the equation (1) can be true only when $|z| = |w| =1$ (Reciprocal of 1 is 1). Modulus can be equal only when one of the following is satisfied:
