R+b=7 <br> 3.75r+2.75b=22.25
stiv31 [10]

Answer:

Step-by-step explanation:

hello :

r+b=7... (*)

3.75r+2.75b=22.25.... (**)

use (*) :  r = 7 - b

put this value in (**) :

3.75(7 - b)+2.75b =  22.25

26.25 -375b +2.75b = 22.5

-375b +2.75b = 22.5 - 26.25

- b = -3.75

so : b  = 3.75

but : r = 7 - b

r = 7 - 3.75

r = 3.25

Help quickly please!!!
sineoko [7]

Answer:

M= -2

B=1

Step-by-step explanation:

<u><em>Y-intercept</em></u><em> is the point where the line crosses through the y line, so you can clearly see that that point is (0,1) we only write the y value because for a y intercept the x value will always be zero</em>

<em><u>Slope</u></em> <em>is the rise over run, meaning how much the y value changes over how much the x value changes, so for the two points we use our formula:</em>

\frac{y1-y2}{x1-x2}

<em>So now input how much it changes by adding the numbers from each coordinate:</em>

\frac{(-3)-(1)}{(2)-(0)}

<u>Simplify:</u>

<u />\frac{-4}{2}<u />

<em>But we write it as:</em>

-4/2

<em>This is because this looks more like division</em>

<u>Divide:</u>

-4/2=-2

So, your slope is <em><u>-2</u></em> and the y- intercept is <em><u>1</u></em>

I hope this helps u pls give a brainliest and a thx ;)

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9
Zinaida [17]
The probability of profiting $5.2 million is 5% = 0.05

The probability of profiting $0.9 million is 50% = 0.5

The probability of breaking even, meaning no profit gain, is 45% = 0.45

Expected profit values of the CD is given by
(0.05×5.2) + (0.5×0.9) + (0.45×0) = 0.26+0.45+0 = 0.71 million
