To calculate percent change:
(difference between original and new)/original * 100
(19-15)/15 * 100 =
4/15 * 100 = 26.7 % increase
Answer:
The answer is D. Green; The experimental probability is 22.7%, and the theoretical probability is 15%.
For this case we have the following expression:
x ^ 2 + 15x + 56
We can factor this expression to find the possible dimensions of the rectangle.
Factoring we have:
(x + 7) (x + 8)
Answer:
the possible dimensions are:
(x + 7) * (x + 8)
Answer:
Abelito had the greater average speed
Step-by-step explanation:
Given
Bobby:


Abelito


Required:
Who had a greater average speed
Average speed (S) is calculated as:

We will make use of mph (miles per hour) as the unit of speed.
For Bobby:

Convert minute to hour


For Abelito

Convert minute to hour


By comparison: 12.5mph > 8mph
Hence: Abelito had the greater average speed
The answer is 3x^2 - 2.
x^2+3y-3+2x^2-3y+1
Add the like terms together, you get 3x^2 - 2
