The data set below gives the number of points Micah scored during each basketball game this season. (5, 12, 27, 44, 30, 9, 18, 21, 26, 21, 6) Is there an outlier? If so, what is it?
Answer:
Yes there is an outlier and it is 44
Step-by-step explanation:
Outliers are values that seems to be far greater and lower than the rest of the data
From the given data we can see that 44 is much greater than the rest of the data making it an outlier in the data set
The removal or addition of the value when calculating the mean will make a huge difference in the resulting mean of the data. That's why they are called an outlier

sarah lost her science book her school charges a lost book fee equal to 75% of the cost of the book sarah recieved a notice she owes the school $60 for the book how much did the school pay for the book
Answer: $80
Step-by-step explanation:
You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.
Therefore
$60 = 75%
Now we have to find out what amount of money would be equivalent to 100%:
To do this, find out what amount of money would be equivalent to 25% first.
You can do this by dividing both values by 3.
60 / 3 = 20
75 / 3 = 25
So now $20 = 25%
Now find 100% (which is the original amount) multiply each value by 4 :
$80 = 100%
So the school payed $80 for the book.
hope this helps :)

Question and answer choices are in the screenshot below
Please don't spam
Answer:
B I think
Step-by-step explanation:
Answer: Choice B
=========================================================
Explanation:
Let's say we had segment PQ. So the endpoints are P and Q. Let M be the midpoint of segment PQ.
Furthermore, let P have coordinates (x+6, y/3). Dividing by 3 is the same as multiplying by 1/3. So (1/3)y is the same as y/3.
Let Q have the coordinates (r,s). The goal is to express r and s in terms of x and y, as the answer choices indicate.
The midpoint M is located at (2,-5)
---------------------
For now, let's focus on the x coordinates of each point
x coordinate of P is x+6x coordinate of Q is rx coordinate of M is 2If we average the x coordinates of P and Q, we'll get the x coordinate of M
So we add up (x+6) and r, then divide by 2, and we should get 2 as a result
( (x coord of P) + (x coord of Q) )/2 = x coord of M
( (x+6) + (r) )/2 = 2
(x+6+r)/2 = 2
Let's solve for r
(x+6+r)/2 = 2
x+6+r = 2*2
x+6+r = 4
r = 4-x-6
r = -2-x
The x coordinate of point Q is -2-x
----------------------
We'll follow the same basic idea for the y coordinates
The y coordinate of P is y/3The y coordinate of Q is sThe y coordinate of M is -5We then get
( (y coord of P) + (y coord of Q) )/2 = y coord of M
( (y/3) + (s) )/2 = -5
(y/3) + s = -5*2
(y/3) + s = -10
Now solve for s
(y/3) + s = -10
s = -10-(y/3)
This is the y coordinate of point Q.
------------------------------
We found
x coordinate of Q is -2-xy coordinate of Q is -10-(y/3)Point Q is therefore located at (-2-x, -10-(y/3) )
This points to choice B as the final answer.

Amalie's second-hand car cost 3,50,000. She spent another 21,20,000 on repair. She was still not satisfied
with the condition of the car and sold it at a loss of 10%.
PER
At what price did Amalie sell the car?
9514 1404 393
Answer:
22,23,000
Step-by-step explanation:
The amount Amalie had invested in the car totaled ...
3,50,000 +21,20,000 = 24,70,000
If she sold it for 100% -10% = 90% of that value, its selling price was ...
24,70,000 × 0.90 = 22,23,000

Answer:
See Explanation
Step-by-step explanation:
The question could not be solved because you did not include the image of the prism.
However, from the options; it can be deduced that the prism is a rectangular prism
To calculate the volume of a rectangular prism, you consider the following parameters:
LengthWidthHeightAnd the Volume is then calculated by the products of the above parameters.
[tex]Volume = Length * Width * Height[/tex]
Take for instance, the attached image:
[tex]Length = 5[/tex]
[tex]Width = 8[/tex]
[tex]Height = 2[/tex]
[tex]Volume = 5 * 8 * 2\ units^3[/tex]
or
[tex]Volume = 80\ units^3[/tex]

The value for angle [tex]x[/tex] will be [tex]70^0[/tex] .
What is Angle ?Angle is when two rays meet together then the space between them is angle.
We have,
[tex]x=?[/tex]
A triangle with one of its angle equals to [tex]55^0[/tex] and two sides are equal .
So,
"When two sides are equal then the interior angles opposite to these lines are also equal".
So,
According to the above mentioned theorem the angle other than the angle [tex]x[/tex] will be [tex]55^0[/tex] .
Now, Using angle sum property,
[tex]x+55^0+55^0=180^0[/tex]
[tex]x=180^0-110^0[/tex]
[tex]x=70^0[/tex]
So, the value of [tex]x[/tex] is [tex]70^0[/tex] which is find out using the angle sum property.
Hence, we can say that the value for angle [tex]x[/tex] will be [tex]70^0[/tex] .

A number went into this machine and 57 came out.
What number went in?
Answer:
47.5
Step-by-step explanation:
47.5=100%
57=120%
The input value is 47.5 when the output is 57.
What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
When the output is 120%, the input is 100%.
And the output is 1.2 times the input.
So, we have the output 57.
To find the input number:
Use division process,
