Explicaciones paso a paso:
Primero es necesario aclarar que el porcentaje en total es igual a 100%
Entonces si en total todos los ensayos dan un total de 50 ensayos lo único que se debería de hacer para conocer la probabilidad de cada número sería multiplicar por 2 el número de veces que ocurrió cada número.
Respuesta:
5 = 34%
6 = 16%

Which linear function has a y-intercept of -5?
2x+y=-10
x-y=-5
x-3y=15
-x+4y=20
Answer:
It could be =15 or =0
Step-by-step explanation:Multiplying each side of −3x+4y=20
by 2 gives −6x+8y=40
. Adding each side of −6x + 8y = 40 to the corresponding side of 6x+3y=15
gives 11y=55,ory=5
. Finally, substituting 5 for y in 6x+3y=15
gives 6x+3(5)=15,orx=0
.
Answer:
x-3y=15 has a y-intercept of -5
Step-by-step explanation:
A y-intercept occurs when x = 0. So, when x = 0, which function has a y-value of -5?
Plug in 0 for all the values of x and solve for y.
1. 2(0)+y=-10; y=-10
2. (0)-y=-5; y = 5
3. (0)-3y=15; y = -5
4. -(0)+4y=20; y= 5
What is the volume of this figure?
Answer:
1920
Step-by-step explanation:
I'm just doing it my way because it feels easier, but multiply 14 x 20 x 8 to get the volume of the entire figure.
Then we subtract that box of air which is 10 x 4 x 8.
So 14 x 20 = 280
280 x 8 = 2240
Then we find the volume of the missing part which is
10 x 4 = 40
40 x 8 = 320.
We get 2240 - 320 = 1920

Part A: The average rate of change between the 2nd and 3rd point is
Select a Value
(2,6,10,-6,-10)
Part A: The average rate of change between the 3rd and 4th point is
Select a Value
(2,6,10,-6,-10)
Part B: The average rate of change between the 2nd and 3rd point is
Select a Value
(2,6,10,-6,-10)
Part B: The average rate of change between the 4th and 5th point is
Select a Value (6,18,162,-54,-18)
Answer:
6 ; 10
18 ; 162
Step-by-step explanation:
Recall :
Rate of change = Slope = Rise / Run = (y2 - y1) / (x2-x1)
2nd point is (1, 7)
3rd point is (2, 13)
Rate of change = (13 - 7) /(2 - 1) = 6 /1 = 6
3rd and 4th point :
(2, 13)
(3, 23)
Rate of change = (23 - 13) / (3 - 2) = 10 /1 = 10
PART B:
(2, 11) ; (3, 29)
Rate of change = (29 - 11) / (3 - 1) = 18 /1 = 18
(4, 83)
(5, 245)
Rate of change = (245 - 83) / (5-4) = 162 / 1 = 162
!!!!NEED HELP ASAP!!!! NO LINKS OR REPORT
Answer:
Step-by-step explanation:
Infinitely many solutions means that one side of the equals sign is exactly the same as the other side. We can achieve that easily by multiplying through the parenthesis and then combining like terms.
2(6x + 4) - 5x is 12x + 8 - 5x which simplifies down to 7x + 8. That is what goes on the right side of your equation.

Answer:
38
Step-by-step explanation:
The area of a kite is equal to half the product of the diagonals
To find the area we must first find the measures of the diagonals
short diagonal = 2 + 2 = 4
longer diagonal = 8 + 11 = 19
We then calculate the area by multiplying the two diagonals together and then dividing that by 2
A = 19 * 4 = 76
76 / 2 = 38
Hence, the area of the kite is 38m²
38m².
Answer:
Solution given;
diagonal 1=8+11=19m
diagonal 2=2+2=4m
the area of a kite =½*diagonal 1*diagonal 2
=½*4*19=38m²
The area of kite is 38m².

What are the first three terms of the sequence defined by the recursive function an = an-1-(an-2-4), when a5 =-2 and a6 = 0?
-14, 14,- 4
6, 10,8
-2 0,2
2, 8, 10
Answer:
6, 10 and 8
Step-by-step explanation:
Given the recursive function an = an-1-(an-2 - 4), when a5 =-2 and a6 = 0?
a6 = a5 - (a4 - 4)
0 = -2 - (14 - 4)
2 = - (a4 - 4)
-2 = a4 - 4
a4 = -2 + 4
a4 = 2
a5 = a4 - (a3 - 4)
-2 = 2 - (a3 - 4)
-2-2 = - (a3 - 4)
-4 = -(a3 - 4)
4 = a3 - 4
a3 = 4+4
a3 = 8
Also
a4 = a3 - (a2 - 4)
2 = 8 - (a2 - 4)
2-8 = - (a2 - 4)
-6 = -(a2 - 4)
6 = a2 - 4
a2 = 6+4
a2 = 10
a3 = a2 - (a1 - 4)
8 = 10 - (a1 - 4)
8-10 = - (a1 - 4)
-2 = -(a1 - 4)
2 = a1 - 4
a1 = 2+4
a1 = 6
Hence the first 3 terms are 6, 10 and 8

A triangular pyramid has lateral faces with bases of 8 meters and heights of 10
meters. The area of the base of the pyramid is 27.7 square meters.
What is the surface area of the pyramid?
The surface area of the pyramid is
square meters.
Answer:
147.7 m²
Step-by-step explanation:
Area of the triangular faces = 1/2 × base × height
A triangular pyramid has lateral faces with bases of 8 meters and heights of 10 meters.
Hence: 1/2 × 8 × 10 = 40 m²
A triangle has 3 faces, hence, area of the 3 faces = 3 × 40 m²
= 120m²
The area of the base of the pyramid is 27.7 square meters.
Hence, the surface area of the pyramid is calculated as:
Area of the 3 lateral faces of the pyramid + Base area
= 120m² + 27.7 m²
= 147.7 m²
The surface area of the pyramid is 147.7 square meters.

If 2g - 4 = 6, then g =
Answer:
Then g = 5.
Step-by-step explanation:
The only number that fits in g is 5.
2*5 - 4 = 6
So 2 x 5 = 10.
Which the equation is now 10 - 4 = 6.
So the answer is 5.
Answer:
g = 5
Step-by-step explanation:
2g - 4 = 6
2g - 4 + 4 = 6 + 4
2g = 10
2g ÷ 2 = 10 ÷ 2
g = 5
