In a chess club the probability that Shaun will beat Mike is 3/8 .

romanna [79]

Answer:

$\frac{10}{56} = 0.1786$ probability that Shaun loses both games

Step-by-step explanation:

Games are independent, so we find each separate probability, and multiply them.

In a chess club the probability that Shaun will beat Mike is 3/8.

So $1 - \frac{3}{8} = \frac{8}{8} - \frac{3}{8} = \frac{5}{8}$ probability that Shaun loses.

The probability that Shaun will beat Tim is 5/7 .

So $1 - \frac{5}{7} = \frac{2}{7}$ probability that Shaun loses.

What is the probability that Shaun loses both games?

This is:

$p = \frac{5}{8} \times \frac{2}{7} = \frac{5*2}{8*7} = \frac{10}{56} = 0.1786$

$\frac{10}{56} = 0.1786$ probability that Shaun loses both games

The slope-intercept equation is y=mx+b.

The slope formula is $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Our three points are (5,5), (-5,-7) and (0,-1)

Using our slope formula our slope becomes $\frac{-7-5}{-5-5} =\frac{12}{10} =\frac{6}{5}$

Then, if we use one of our points (pick whichever you want, although (0,1) is the easiest) to solve the equation. So, $y=\frac{6}{5}x-1$ . When we solve for x and y, we get -1=0+b, or b=-1.

When we plug that back into the equation, we get $y=\frac{6}{5}x-1$ .
