Answer:
A would be the line of best fit and B would be the oulier
Hey there!
To solve the first problem, I've found it easiest to solve the equation for, say, values –2 through +2 and create a table of values for you to begin graphing this function. You may need to do more depending on the equation itself.
Some points are: (–2, 0.75), (–1, 1.5), (0, 3), (1, 6) and (2, 12). You can check which graph matches up with these points the closest to get your answer of D.
To solve the second problem, you'll need to use the distance equation.
x1 = –4, y1 = 3
x2 = –1, y2 = 1
___________________
√ (x2–x1)^2 + (y2–y1)^2
_________________
√ (–1–(–4)^2 + (1–3)^2
_______________
√ (–1+4)^2 + (–2)^2
____________
√ (3)^2 + (–2)^2
_____
√ 9 + 4
___
√ 13, making your answer D
For your third question, I always just counted the number of units the point was from the line of reflection. You'll count twice diagonally towards the line from point C for this one, staying on the "crosshairs" of the graph. All you need to do then is count two diagonal units along the same line, then you'll get your answer of (2, 6), or D.
For your final question, A and B are immediately out, since they won't be parallel to the 4x equation. You'll need to solve both of your remaining equations for y with 2 plugged in for x; whichever one equals 7 will be your answer. In this case, it will be D.
Hope this helped you out! :-)
Answer:
5 is the median
Step-by-step explanation:
The "median" is the "middle" of the set of numbers. Considering there are 13 total numbers, making it un-even, there can be an equal amount of numbers taken off of each side with a middle number remaining. That middle number will be your median..
The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.
The area of a semi-circle is half the area of a full circle, so we can find it by using:
If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:
or about 39.25
The area of a triangle is:
So we can plug in the known values to find the area to be:
When we add the areas of the two sections together, we get an exact answer of:
(60 + 12.5pi) cm^2
or about
99.25 cm^2
