Answer:
B and E
Step-by-step explanation:
To verify which are solutions, substitute the given values into the left side of the equation and if equal to the right side then they are solutions.
A
2(20)² + 18(20) = 800 + 360 = 1160 ≠ 20 ← not a solution
B
2(1)² + 18(1) = 2 + 18 = 20 ← solution
C
2(- 2)² + 18(- 2) = 2(4) - 36 = 8 - 36 = - 28 ≠ 20 ← not a solution
D
Is a repeat of C
E
2(- 10)² + 18(- 10) = 2(100) - 180 = 200 - 180 = 20 ← solution
F
2(- 1)² + 18(- 1) = 2(1) - 18 = 2 - 18 = - 16 ≈ 20 ← not a solution
Then B and E are solutions to the equation
Answer:
Associative property
Step-by-step explanation:
Answer:
Option D) The data are continuous because the data can take on any value in an interval
Step-by-step explanation:
We are given the following in the question:
Data: The heights (in feet) of different buildings
Discrete and continuous data:
- Discrete data is the data that cannot take values in decimals and continuous data can take values in decimals.
- Continuous data can take any value within an interval.
- Discrete data cannot take all the value within an interval.
- Discrete data is counted where as continuous data is measured.
Thus, height is a continuous data since it can take any values within an interval and is measured.
Thus, the correct answer is
Option D) The data are continuous because the data can take on any value in an interval
These are vertical angles so they are equal.
3x + 50 = 6x - 10
50 + 10 = 6x - 3x
3x = 60
x = 20 answer
Answer:
30 units
Step-by-step explanation:
In order to find the length of the 3rd side of the triangle, the hypotenuse, you can use the Pythagorean Theorem. Using this method, you get 5^2+12^2=169. The square root of 169 is 13.
5 + 12 + 13 = 30 units.
