100 students participate in sport or music.60 participate in sports and 50 participate in music. How many students participate in both activities?Using Venn-diagram,find the number of students who participate only in music.(help me)
Answer:
40 students participate only in music.
Step-by-step explanation:
When you add the two groups together, you get 50 + 60 = 110. But there are only 100 students, so 10 of them must have been counted twice (they do music AND sports. Put 10 in the middle part of the Venn diagram (image2).
Subtract 10 from each of the two groups to find the number of students taking only one of the two subjects. For example, there are 50 music students, but 10 of them also do sports, so 50 - 10 = 40 students do only music. (There are 60 - 10 = 50 students who participate only in sports.) (image3).

What is the equation of a circle that has a diameter of 10 units if its center is at (3,8)?
Answer:
Step-by-step explanation:
[tex](x-3)^2+(y-8)^2 = 25[/tex]
The equation of circle: (x - 3)² + (y - 8)² = 25
What is equation of circle?An equation of circle with center (h, k) and radius 'r' is,
(x - h)² + (y - k)² = r²
For given example,
a diameter of circle = 10 units
So, the radius would be (r) = 10/2
r = 5 units
And the center (h, k) = (3, 8)
So, the equation of the circle would be,
⇒ (x - 3)² + (y - 8)² = 5²
⇒ (x - 3)² + (y - 8)² = 25
Therefore, the equation of circle: (x - 3)² + (y - 8)² = 25

Step-by-step explanation:
u need to put that equations in the graph
Answer:
y = -(x + 3)^2 - 5 (this is Answer b)
Step-by-step explanation:
Identify the coordinates of the vertex (h, k) by looking at the graph: the x-coordinate, h, is -3 and the y-coordinate is -5. The graph opens down, so the function begins with a negative sign: y = -(x + 3)^2 - 5 (this is Answer b).

B.
The situation can be modeled by an exponential growth function with a percent change of 11%.
C.
The situation can be modeled by an exponential decay function with a percent change of -11%.
D.
The situation can be modeled by an exponential growth function with a percent change of 10%.
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

Solve the system of equations using subtraction. 2x-4y= -12 2x+y=8 plz help
Answer:
x=2, y= 4
Step-by-step explanation:
Equation 1 is 2x-4y = -12
Equation 2 is 2x+y = 8
Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).
Simplifying we get -5y = -20 and y =4
Substituting y =4 into original equation back we get 2x -4(4) =-12
This equals 2x -16 =-12 and 2x = 4 and x =2

Volume without holes = 3 x 6 x 11 = 198 cubic inches.
Calculate volume of one hole:
3.14 x 0.5^2 x 3 = 2.355 cubic inches
There are 3 holes: 3 x 2.355 = 7.065
Subtract volume of the holes from the brick:
198 - 7.065 = 190.935 cubic inches.
Rounded to the nearest tenth: 190.9 cubic inches.
Answer:
190.9 inches^3
Step-by-step explanation:
First of all we have to find the total volume:
V = dimension 1 x dimension 2 x dimension 3
V = 3 x 6 x 11 = 198 inches^3
now we have to find the volume of the cylinders:
V= radius^2 x pi x height = 0.5^2 x 3.14 x 3 = 2.355 inches^3
the cylinders are three so:
V = 2.355 x 3 = 7.065 inches^3
at least we have to subtract this value at the total volume:
V= 198 - 7.065 = 190.935 = 190.9 inches^3

Mark is going to an awards dinner and wants to dress appropriately. He had one blue shirt, one white dress shirt, one black dress shirt, one pair of black slacks, one pair of grey slacks, and one red tie. All six of marks possible outfits are listed below
Answer:
All the four statements are true , which are -
(A) The subset contains contains of all the outfits that have grey slacks .
(B) The subset contains contains of all the outfits that have grey slacks and red tie .
(C) The subset contains contains of all the outfits that have grey slacks and blue shirt .
(D) The subset contains contains of all the outfits that do not have black slacks .
Step-by-step explanation:
We are given with Outfit 2 , 4 and 6
Outfit 2 - Blue grey red
Outfit 4 - White grey red
Outfit 6 - Black grey red
(A) Since only 2,4, and 6 contain grey slacks, and no other outfit contains grey slacks, those are the subsets that contain grey slacks. Thus , this statement is true .
(B) Just outfits 2, 4, and 6 have grey slacks and a red tie, proving the statement. Other clothes do not include grey slacks and a red tie; they may include a red tie but not both grey slacks and a red tie. Hence , the statement is true .
(C) Since the outfit 2 has grey slacks and a blue shirt, the statement is correct; no other outfit has both grey slacks and a blue shirt. Therefore , this statement is also correct .
(D) The argument is correct since all of the subsets contain grey slacks and no black slacks.
Hence , all the options A , B , C , D are correct and describes the subset .
