Y=(1/2 x)-2
My Work:
Say that the slop is "a" and that the y-intercept is "b".
For the slope:
First coordinate equation: -3=-2a+b
Second coordinate equation: -1=2a+b
Combine the equations. -3-(-1)=-2a-(2a)+b-(b)
Break down the parenthesis. -3+1=-2a-2a+b-b
Simplify the equation. -2=-4a
Divide both sides by -4 to get the answer to the slope. a=1/2
For the y-intercept:
Use the second coordinate's equation and the now known slope. -3=-2*1/2+b
Multiply -2 by 1/2 (Order of Operations). -3=-1+b
Add +1 to both sides to cancel the -1. -3+1=b
Finally, solve the solve -3+1 to get the answer to the y-intercept. b=-2
Answer:
Step-by-step explanation:
In a coin toss the probability of tossing a head is 0.5 (50% head/50% tails)
If n is the number of rounds and 2n the number of coins tossed (one for each player), the probability of having m heads tossed is:
R is the number of cases (combination of coins tossed) that gives a m number of heads. Each case has a probability of 
so:
<u>For example, to toss 4 heads in 5 rounds: </u>
Wouldn’t be a,or d. I would honestly say B..
Answer:
Unit rate of oreos = 19.23 cents/oz
Unit rate of Chips Ahoy = 17.86 cents/oz
The cheapest and most affordable is the chips ahoy because it has a lower unit rate.
Step-by-step explanation:
Oreos 2.98 for 15.5.Oz or chips ahoy for 2.50 for 14.Oz I pick chips ahoy BUT ITS ASKING UNIT RATE CENTS PER OZ
We would be finding the Unit Rate of each product.
For Oreos
Oreos $2.98 for 15.5.Oz
We convert dollars to cents
1 dollars = 100 cents
2.98 dollars = x
x = 2.98 × 100 cents
= 298 cents
Hence, the unit rate in cents/oz
= 298 cents/15.5 oz
= 19.225806452 cents/oz
= 19.23 cents/oz
For Chips ahoy
$2.50 for 14.Oz
We convert dollars to cents
1 dollars = 100 cents
2.50 dollars = x
x = 2.50 × 100 cents
= 250 cents
Hence, the unit rate in cents/oz
= 250 cents/14 oz
= 17.857142857 cents/oz
= 17.86 cents/oz
Therefore, the cheapest and most affordable is the chips ahoy because it has a lower units rate.
