example
if ab=6
and a=3
b=2

a. 6 must be factor of 3 or 2 FALSE
b. 3 must be a factor of 3 OR 2 TRUE

B is true

Which statement is true about the following system of equations?
3x-1/2y=1
x+2y=7

Answers

Many many true statements could be offered regarding those two equations.
Sadly, until you share the list of choices you're looking at, there's no way for
anyone to help you choose the best one.

$\begin{cases} 3x- (1)/(2)y=1 \ \ / \cdot 4\n x+2y=7 \end{cases}\n\n\begin{cases} 12x- 2y=4 \n x+2y=7 \end{cases}\n+ -------\n13x = 11\ \ / :13\n\nx=(11)/(13)$

$x+2y=7 \n \n (11)/(13)+2y=7\n \n2y=7-(11)/(13) \n \n2y=(91)/(13)-(11)/(13)\n \n2y =(80)/(13)\ \ / \cdot ((1)/(2))\n \ny=(40)/(13) \n\n\begin{cases} x=(11)/(13)\n y= (40)/(13) \end{cases}$

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

Answers

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 $(n!)/(r!\cdot(n-r)!)$

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

$(75!)/(2!(75-2)!)$

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

After simplification we will get $(75\cdot 74\cdot 73!)/(2!\cdot73!)$

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

after more simplification we will get $(75\cdot 74\cdot)/(2!)$

Finally, we will get $(75\cdot 74\cdot)/(2)=75\cdot37=2775$

I think the answer is 2774 but dont quote me on it
