Hi there!
1st question: answer: either AB, EF or FG
We were looking for a linear line that was decreasing. Therefore, we were looking for a straight line downwards in the graph. This can be AB, EF or FG.
2nd question: answer: EF.
The line EF is the line that decreases the fastest: the distance from home decreases in a short time, and therefore Miguel is travelling the fastest over there.
Answer:
X=20
Step-by-step explanation:
The 3 angles all add up to 180º because they are a straight line.
3x + 80 + 2x = 180
5x + 80 = 180
5x + (80-80) = 180-80
5x = 100
5x/5 = 100/5
X=20
Hope this helps!

Answer:
a) C. The random variable is discrete. The possible values are xequals0, 1, 2,....
b) B. The random variable is continuous. The possible values are x greater than or equals 0.
Step-by-step explanation:
Discrete variables are countable in a finite amount of time. Continuous variables can be infinitely many. They rather assume values in a range.
<u><em>(a) Is the number of hits to a Web site in a day discrete or continuous? </em></u>
C. The random variable is discrete. The possible values are x equals 0, 1, 2,....
<u><em>(b) Is the weight of a Upper T dash bone steak discrete or continuous?</em></u>
B. The random variable is continuous. The possible values are x greater than or equals 0.
Answer:
Step-by-step explanation:
In this problem we have a horizontal ellipse, because the major axis is the x-axis
The equation of a horizontal ellipse is equal to
where
(h,k) is the center of the ellipse
a and b are the respective vertices distances from center
we have
vertices at (7, 0) and (-7, 0)
co-vertices at (0, 1) and (0, -1)
so
The center is the origin (0.0) (The center is the midpoint of the vertices)
a=7
b=1
substitute
