What is the median of this set of data?
362, 187.211,298,331,250, 347, 199
Answer:
274
Step-by-step explanation:
187, 199, 211, 250, 298, 331, 347, 362 <<< First order least to greatest
187, 199, 211, 250, 298, 331, 347, 362 <<< Since there are an even amount of terms, take the middle TWO numbers
(250+298)/2 = 548/2 = 274 <<< Take the mean of the two numbers
Your final answer is 274!
Hope this helps!
Answer:
274
Step-by-step explanation:
1.Arrange your numbers in numerical order.
2.Count how many numbers you have.
3.If you have an odd number, divide by 2 and round up to get the position of the median number.
4.If you have an even number, divide by 2. Go to the number in that position and average it with the number in the next higher position to get the median.

Which equation represents circle C
options are in the picture
Answer: (x+4)^2 + (y-1)^2 = 162
Step-by-step explanation:
Equation of Circle : (x – h)^2 + (y – k)^2 = r^2
(h, k) is the center of the circle, r is the radius
The center is (-4, 1), plug it in to get:
(x+4)^2 + (y-1)^2 = r^2
To find the radius we can use the distance formula to find the distance between C and P:
Distance Formula: d = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
Plug in C: (-4, 1) and P:(5, -8) to get [tex]\sqrt{162}[/tex]
So, the equation is:
(x+4)^2 + (y-1)^2 = [tex]\sqrt{162} ^{2}[/tex]
(x+4)^2 + (y-1)^2 = 162

Hey! this is a hard one...but i could be wrong.....
Step-by-step explanation:
Ok so let's do this together...it can't be A nor B because it DOES NOT =81...... nor =9!!! it can't be D either! because where do we get the 81 from?????? and etc..............and now, B and A it could be both of the answers you are thinking and i am thinking too! but B and A has the same writing and problem but not the same answer....so let's see this together....B. is (x-4)2 = (y+1)2 = 81 and A. is (x-4)2 = (y+1)2 = 9...so...when we do that looks like it is not B. either!! Nor A! Nor D....it is *dun dun dun dunnnnnnn* C!!!!! The answer is C. (x-4)2 + (y +1)2 = 162!!
Hope this helped and sorry it took so long to type!!!!Jina sold t-shirts at a festival. She made $3 for each t-shirt she sold. Her expenses were $27. If she made a profit of $51, how many t-shirts did she sell?
Answer:3x+27=51
27-27=0
51-37=x
X=14
Step-by-step explanation:
Per shirt would be the “x” part of the equation. Meaning 3x would be the cost per shirt. And if her total 51, and it were to be a profit, you would add $27 to 3x.
The total cost of buying apples from a farm stand is shown in the table.
What is the cost per pound of apples?
A $1.50 per Sound
B. $2.00 per pound
C. $2.50 per pound
D. $3.00 per pound
Answer:
$1.50 per pound
Step-by-step explanation:
got same question and got it right.
The cost per pound of apples is given as $1.50 per pound.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
From the table,
Let the cost of the apples is directly proportional to the pound of x apples,
y = kx
Where k represents the cost of each pound of apply,
From the table consider an ordered pair,
x = 2, y = 3
Now,
3 = 2k
k = 3 / 2
k = 1.5
Thus, the cost per pound of apples is given as $1.50 per pound.

my answer was -27
Step-by-step explanation:
Answer:

Step-by-step explanation: -2 -17 +12- -4
-2 -17 is -19 since they are both negative. If you add 12 positive to that it becomes -7. Since you are subtracting or taking away -4, think of it as adding 4 instead. This leaves you with -3.

Tim tiene 39 pares de audífonos y 13 reproductores de música. Tim quiere vender todos los audífonos y los reproductores de música en paquetes idénticos. ¿Cuál es el mayor número de paquetes que Tim puede hacer?
Answer: 13 packages.
Step-by-step explanation:
This can be translated to:
Tim has 39 pairs of headphones and 13 music players. Tim wants to sell all the headphones and music players in identical packages. What is the largest number of packages that Tim can do?
To solve this we must find the largest common factor between 39 and 13.
to do this, we divide the smaller number by different integers, and see if the result also divides the larger number into an integer.
13/1 =13 and 39/13 = 3
So 13 is the largest common factor.
This means that we can make 13 packages, each with:
39/13= 3 headphones
13/13 = 1 music players

Which expression is equivalent to 5a+20?
Answer: 5(a+4)
Step-by-step explanation:
An expression that is equivalent to 5a + 20 is: 5 ( a + 4 ).
Since 5 times a equals 5a and 5 times 4 equals 20.
Therefore, 5 (a + 4) is equivalent to 5a + 20.
On a sine function y = Asin(Bx) +C , the maximum value is 19 and the minimum value is -5. Which of the following must be the value of |A| - C ?
Answer:
|A| - C = 5
Step-by-step explanation:
The maximum value that a sine function can have is 1, and the minimum value is -1.
With this information, to find the minimum value of y, we can use sin(Bx) = -1, and to find the maximum value, we can use sin(Bx) = 1. Then, we have that:
19 = A + C
-5 = -A + C
Summing both equations, we have:
14 = 2C
C = 7
Now, to find the value of A, we can use the first equation:
19 = A + C
19 = A + 7
A = 12
So the value of |A| - C is:
|12| - 7 = 12 - 7 = 5

Step 1) Divide the figure into shapes
Triangle: 9 x 10
Large rectangle: 8 x 17
Small rectangle: 5 x 9
Smaller rectangle (bottom): 4 x 6
Step 2) Find the area of each shape
Triangle: A = 1/2 x 9 x 10 = 45
Large rectangle: A = 8 x 17 = 136
Small rectangle: A = 5 x 9 = 45
Smaller rectangle (bottom): A = 4 x 6 = 24
Step 3) Add the areas together
A = 45 + 136 + 45 + 24 = 250 square kilometers
