2x²
quadratic and monomial
- 2
I'm guessing linear since x = - 2 and y = - 2 are both lines and it's a constant
3x - 9
linear and binomial
- 3x² - 6x + 9
quadratic and trinomial
Reinterpreting the question, it's asking us to find which coin has a closer probability to 50% of getting either heads or tails.
Coin A
205 / 500 = .41 = 41%
Coin B
120 / 250 = .48 = 48%
Since 48% is closer to 50% than 41% is, coin B is the fairest.
Well...
The difference between 7 and 4 is 3.
That difference cost $6.75.
Each box cost $6.75/3=$2.25
Good luck!

<u>Answer:</u>
<u>Distance:</u> 6x + 15.5y > 55.5
<u>Time:</u> x + y > 4.5
<u>Step-by-step explanation:</u>
We are given that Martha is training for a duathlon and she covered a total distance of over 55.5 miles in more than than 4.5 hours of training.
Also, she runs at a speed of 6 mph and bikes at a rate of 15.5 mph.
We are to write inequalities representing the distance she traveled and the total time she spent training.
<u>Distance:</u> 6x + 15.5y > 55.5
(formula for distance = speed x time so speeds for running and biking are multiplied by their number of hours)
<u>Time:</u> x + y > 4.5
(she trained for more than 4.5 hours, x hours for running and y hours for biking.
Answer:
A) Area of sector = 2.5 in².
Step-by-step explanation:
Given : If the area of the circle below is 10 in².
To find : What is the area of the shaded sector .
Solution : We have given that
Area of the circle = 10 in².
Formula of area of circle = .
= 10
=
Area of sector =
Plugging the values
Area of sector = * 10.
Area of sector = 2.5 in².
Therefore, A) Area of sector = 2.5 in².
