Use the substitution method to solve the system of equations. Choose the
Hatshy [7]

Answer:

(3, 2) is the ordered pair for the given system of equations.

Step-by-step explanation:

Given:

2 x+ y = 8.......................(i)

y = - x + 5........................(ii)

<u>Put y = - x + 5 in equation (i)-</u>

<em>2 x + ( - x+ 5) = 8</em>

<em>2 x - x + 5 = 8</em>

<em>x = 8 - 5</em>

<em>x = 3</em>

<u>Now put x = 3 in equation (ii)-</u>

<em>y = - 3 + 5</em>

<em>y = 2</em>

Hence the (3, 2) is the correct ordered pair.

If a coin is flipped 75 times, in how many ways could there be exactly two tails?
Dimas [21]

Answer:

2775 ways

Step-by-step explanation:

We have been given the case to choose exactly two tails when flipped 75 times  means  ^{75}C_2

Since, ^nC_r is equal to \frac{n!}{r!\cdot(n-r)!}  

Here n =75, r=2 substituting the values we will get

\frac{75!}{2!(75-2)!}

n!=n\cdot (n-1)\cdot (n-2).....1

After simplification we will get  \frac{75\cdot 74\cdot 73!}{2!\cdot73!}

Cancel out the common term that is 73! we will get

after more simplification we will get \frac{75\cdot 74\cdot}{2!}

Finally, we will get \frac{75\cdot 74\cdot}{2}=75\cdot37=2775
