Answer:

A. 35.69%

B. 62.77%

Step-by-step explanation:

In this case, what we must do is calculate the probability supported with the data in the table.

Part A.

What is the probability that a randomly selected student is a 7th grader?

Here the total is all the students that would be the sum of all the grades, which are 325 students.

the number of 7th graders is 116, so the probability is:

116/325 = 0.3569

that is, 35.69%

Part B: What percentage of the students interviewed play Video games?

The total number of students is the same 325 and of those 204 play video games, therefore:

204/325 = 0.6277

that is, 62.77%

A polygon is broken up into 4 non-overlapping triangles by drawing lines from one vertex to all other non-adjacent vertices. Wha
aliina [53]

Answer :

The Correct Option is B) Hexagon

Step-by-step explanation :

Let number of sides in a polygon be n

The triangles are created by drawing the diagonals from one vertex to all the others.

Since there is no overlapping of the triangles so no diagonal will be drawn back to itself, and the diagonals to each adjacent vertex would lie on top of the adjacent sides, therefore number of diagonals from a single vertex is three less the the number of sides, or n - 3 and the number of triangles is one more than that, so n - 2.

⇒ Number of triangles = number of sides in polygon - 2

⇒ Number of triangles = n - 2

⇒ n = 4 + 2

⇒ n = 6

And the polygon containing 6 sides is called Hexagon

Hence, the correct Option is B) Hexagon

euqation of the graph

(1) g(x)= x+3

We have

(2) g(x)=f(x)+k

(3) g(x)=x-1+k

(1) =(3)

x+3 =x -1 + k

-x      -x

3= -1+k

k= 4

Pls help this is major, ill mark u brainliest
Lera25 [3.4K]

Answer:

105

Step-by-step explanation:

A=lw   A=(.5)πr²

to get the area of the shaded parts you have to subtract the area of the semicircle from the area of the rectangle

A=(16)(9)

A=144

A=\frac{(3.14)(5)^2}{2} A=\frac{(3.14)(25)}{2} A=\frac{78.5}{2}

A=39.25

subtract the areas

144-39.25=104.75

104.75 ≅ 105
