Answer:

P(Male = 2) = 63.9%

Step-by-step explanation:

40000C2 / 50000C2

[(40000 * 39999) / (1*2)] / [(50000 * 49999 *) / (1*2)]

3,199,920,000 / 4,999,900,000

0.6399996799935999

P(Male = 2) = 63.9%

Answer:

<h2>A)t=6.7</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

quadratic equation
quadratic equation word problems
solving quadratic

<h3>given:</h3>

h(t) = -4t² + 12t + 100

<h3>to solve:</h3>

t

<h3>tips and formulas:</h3>

<u>the</u><u> </u><u>Ball</u><u> </u><u>will</u><u> </u><u>hit </u><u>the</u><u> ground</u><u> </u><u>when</u><u> </u><u>the</u><u> height</u><u> is</u><u> </u><u>0</u>
<u>solving</u><u> </u><u>quadratics </u><u>using</u><u> </u><u>quadratic</u><u> formula</u>
<u>PEMDAS</u>

<h3>let's solve: </h3>

$step - 1 : \: define$

$- 4 {t}^{2} + 12t + 100 = 0$

$step - 2 : \\ divide \: both \: sides \: by \: - 4$

${t}^{2} - 3t - 25 = 0$

$step - 3 : \\ solve \: the \: quadratic$

$formula : \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac } }{2a}$

$define \: a ,b \: and \: c \\ which \: are \: 1, - 3 \: and \: - 25 \: respectively$

$t = \frac{ - ( - 3)± \sqrt{ {( - 3)}^{2} - 4.1. - 25 } }{2.1}$

$t = \frac{ 3± \sqrt{ 9 + 100} }{2}$

$t = \frac{3 + \sqrt{ 109 } }{2}$

$t = \frac{3 - \sqrt{ 109 } }{2}$

$t = 6.7 \\ t = - 3.7$

$as \: we \: know \: time \: cannot \: be \: negative$

$\huge \therefore \: t = 6.7$

Part a - obtaining conversion factors from unit equality relationships in an experiment you are performing, your lab partner has

DanielleElmas [232]

Solution:

As we given that $1 inch=2.54 cm$

then using this conversion factor we can write $28.4 inch=28.4* (1 inch)$

and further it can be written as

$28.4* (1 inch)*(2.54 cm/1 inch)=28.4*2.54 cm= 72.136 cm$

Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.
