1) 1/2 * 1/2 = 1/4

2) 43/100 of mine were heads, and (.43)^2 = .1849

3) 1/2 * 1/2 = 1/4

4)57/100 of mine were tails, and (.57)^2 = .3249

5) 1/2 * 1/2 * 2 (multiply by 2 because order doesn't matter) = 1/2

6) .43 *.57 = .2451

7) There is probably a difference becasue there wasn't enough data. The more times you flip the coin, the closer you'd get to 1/2 head 1/2 tails (theoretically), but you can't flip a coin an infinite amount of times, so it (usually) will not give you an exact 1:1 ratio between heads and tails

chubhunter [2.5K]

Answer:

It will take \frac{45W}{P} weeks to recycle a total of 45 kg of paper

Step-by-step explanation:

W represents the number of weeks the office has been on the new recycling plan

P represents the total kilograms of paper recycled.

It took weeks to recycle P kilograms of paper = W

It took weeks to recycle 1 kilogram of paper =\frac{W}{P}

It took weeks to recycle 45 kilograms of paper =\frac{W}{P} \times 45

Hence It will take \frac{45W}{P} weeks to recycle a total of 45 kg of paper

Papessa [141]

Answer:

Y= -12x + 150

Step-by-step explanation:

1. You do the change in y over the change in x to get the slope.

y1 - y2 / x1 - x2 and you get the slope of -12

2. Making a point-slope form equation

y-y1=m(x-x1)

y-138= -12(x-1)

3. Turning point-slope form equation to slope-intercept

y-138= -12(x-1)

distributive property

y-138=-12x+12

add 138 on both sides

<h2><u> y= -12x+150</u></h2>
