Answer:
a. median 1.5
Step-by-step explanation:
If you sort the numbers from least to greatest, the middle numbers are 1 and 2, so the median is the middle of those, 1.5. And the mean is 2.75, so it can't be the others.

Is (-3-2c)/(-3) the same as (2c+3)/(3)??
(I believe they are the same, but just checking.)
Answer:
Yes, they're the same.
Step-by-step explanation:
-3-2c can be re-written as -1(2c+3) and -3 can be re-written as -1(3). So you can rewrite the fraction as -1(2c+3)/-1(3). The -1's go away and the new fraction is (2c+3)/3.
11. An astronaut travels 32 million miles to Mars, turns around and comes back the same way, ending up exactly where he started his trip. What is his displacement?
Answer:
0
Step-by-step explanation:
Since displacement is the distance between the journey starting point and the final point if they both are the same the difference becomes zero and hence the displacement.
Displacement = final point - initial point
(both are same)
= same - same
= 0
Use the distributive property to remove the parentheses.

A tray of cake samples contains a variety of flavors.
vanilla 25
strawberry 1
lemon 2
red velvet 3
chocolate 2
What is the probability that a randomly selected piece of cake will be red velvet?
Write your answer as a fraction or whole number.
Answer: 1/11
Step-by-step explanation:
The probability that the selected piece will be red velvet is equal to the amount of red velvet cake divided by the total amount of cake.
Therefore, it would be 3/(25+1+2+3+2)
= 3/33
= 1/11 when simplified

Answer:
x^2y−7xy+10xy^2
Step-by-step explanation:
(the first y isn't up but I tried)
anyways, hope this helped! :)
Answer:
[tex]4x^2y-7xy+10xy^2[/tex]
Step-by-step explanation:
We have [tex]\left(6x^2y-8xy+7xy^2\right)+\left(3xy^2-2x^2y+xy\right)[/tex] and need to add them together.
Though complicated at first, we can simplify by taking out the parenthesis and making this whole question into one equation.
[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]
Now combine like terms, meaning you can only add the terms that have the same ending, in math, you cannot add numbers that have different exponents or variables.
Therefore:
[tex]\left6x^2y-8xy+7xy^2\right+\left3xy^2-2x^2y+xy\right[/tex]
[tex]6x^2y-2x^2y-8xy+xy+7xy^2+3xy^2[/tex]

A person standing in the ground throws a ball onto a flat rooftop. The ball rolls around for several seconds. Then the ball falls off the roof, into a puddle of mud. (Please help asap) it’s due shortly!
Answer:
Graph DStep-by-step explanation:
According to the question, the correct graph is D.
It's not A because, the ball is thrown after some pause and the ball doesn't roll on the roof, falls immediately.
It's not B or C because the ball goes up after reaching the roof but should fall down.

what is the slope of the line???
Answer:
slope: 2 as we see, with every increase in x, y increase twice the more.
Step-by-step explanation:
we can can see the y-intercept at 1.so equation: y = 2x + 1The slope of the linear graph in the question obtained using the ratio of the rise and run of the line is 2.
Recall :
Slope = Rise / Run
From the graph :
Rise = y2 - y1 = 5 - (-1) = 5 + 1 = 6
Run = x2 - x1 = 2 - (-1) = 2 + 1 = 3
The slope of the graph can be expressed thus :
Slope = Rise / Run = 6 /3 = 2
Therefore, the slope of the line in the graph attached is 2

help me with angle sum theorem please
Answer:
y = 55°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
100° is an exterior angle of the triangle , then
y + 45° = 100° ( subtract 45° from both sides )
y = 55°

What are the coordinates of A'?
Answer :
A. (0,-2)
B. (-5,-1)
C. (-5,1)
D (5,0)
Answer:
C
Step-by-step explanation:
(-4, 3) 3 units right = +3x = -1
(-1, 3) 2 units up = +2y = 5
(1, 5) A rotation of 90° counterclockwise around the origin can be described in mathematical terms as (x, y) → (−y, x).
(1, 5) → (-5, 1), or C
Answer:
B. (-5, -1)
Step-by-step explanation:
Since we're solving for A :
A (-4, 3) translated 3 units to the right and 2 units up would be A (-4 + 3, 3 + 2), which is A' (-1, 5). Then, we have to rotate it 90 degrees clockwise. This would be (-5, -1), as the formula states (x, y) -> (-y, x), which means the x stays the same but goes to the 'y' position, and the y sign changes and goes to the 'x' position.
So, it would be (-5, -1) :)
