<span>Z=15+2(x+y)
Use distributive property
Z= 15 + 2x + 2y
Subtract 2y from both sides
Z - 2y= 15 + 2x
Subtract 15 from both sides
Z - 2y - 15= 2x
Divide 2 on both sides
Final Answer: Z - 2y - 15(All over 2)= x</span>

Z=15+2x+2y
0=15+2x+2y-15
-2x=15+2y-15
$x= -\frac{15}{2} - y + \frac{15}{2}$

normal distributions:

a function that represents the distribution of many random variables as a symmetrical bell-shaped graph

It is a very common continuous probability distribution

Find the length of side x in simplest radical form with a rational denominator

REY [17]

Answer:

x = 2

Step-by-step explanation:

We can use the sine or cosine ratio to solve for x

Using the cosine ratio in the right triangle and the exact value

cos45° = $\frac{\sqrt{2} }{2}$ , then

cos45° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{\sqrt{8} }$ = $\frac{\sqrt{2} }{2}$ ( cross- multiply )

2x = $\sqrt{8}$ × $\sqrt{2}$ = $\sqrt{16}$ = 4 ( divide both sides by 2 )

x = 2

A deck of cards contains 30 cards with labels 1, 2, . . . , 30. Suppose that somebody is randomly dealt a set of 7 cards of thes

____ [38]

$\displaystyle |\Omega|=\binom{30}{7}=\dfrac{30!}{7!23!}=\dfrac{24\cdot25\cdot\ldots\cdot30}{2\cdot3\cdot\ldots\cdot 7}=2035800$

$\displaystyle\\|A|=\binom{15}{3}\cdot \binom{15}{4}=\dfrac{15!}{3!12!}\cdot\dfrac{15!}{4!11!}=\dfrac{13\cdot14\cdot15}{2\cdot3}\cdot\dfrac{12\cdot13\cdot14\cdot15}{2\cdot3\cdot4}=13\cdot7\cdot5\cdot13\cdot7\cdot15=621075\\\\P(A)=\dfrac{621075}{2035800}=\dfrac{637}{2088}\approx30.5\%$

$\displaystyle\\|A|=\binom{10}{7}\cdot 3^7=\dfrac{10!}{7!3!}\cdot2187=\dfrac{8\cdot9\cdot10}{2\cdot3}\cdot2187=4\cdot3\cdot10\cdot2187=262440\\\\P(A)=\dfrac{262440}{2035800}=\dfrac{243}{1885}\approx12.9\%$
