Answer:
C
Step-by-step explanation:
First we distribute (-2,3) into the equations so 2x+4y becomes 2(-2)+4(3) so that's -4+12 which is 8 making equation 1 correct.
Then x+2y becomes (-2)+2(3) which is 4 so the second equation is correct as well therefore the answer has to be C because of process of elimination
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
The perimeter of the triangle is 13.56 units.
The perimeter of a shape on a coordinate plane is found by finding the distance between all points, and then adding them together. It's easier to write it out than to type so I'll attach a photo of my work.
In this question , it is given that, Perimeter of a rectangular room is 270 yards. Longer side of the room is 15 yards longer than the shorter side.
So if we let shorter side be x, then longer side is

And perimeter is equal to sum of all sides, that is

So the smaller side is 60 yards , and longer side is 15 more then 60 that is 75 yards .
