Dimas is playing a game that uses a number cube.
The sides of the cube are labelled from 1 to 6
The total number of Exhaustive cases
n(S) = {1,2,3,4,5,6} = 6
Step(ii):-
Let E₁ be the event of roll a '2'
n(E₁) = 1
The probability that Dimas wants to roll a '2'
[tex]P(E_{1} ) = \frac{n(E_{1} )}{n(S)} = \frac{1}{6}[/tex]
Let E₂ be the event of roll a '3'
n(E₂) = 1
The probability that Dimas wants to roll a '3'
[tex]P(E_{2} ) = \frac{n(E_{2} )}{n(S)} = \frac{1}{6}[/tex]
But E₁ and E₂ are mutually exclusive events
P(E₁∩E₂) = 0
Step(iii):-
The probability that he will roll a 2 or a 3
we have P((E₁UE₂) = P(E₁)+P(E₂)
= [tex]= \frac{1}{6} + \frac{1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]
[tex]P((E_{1} UE_{2} ) = \frac{1}{3}[/tex]

solve for x
7(8-x) = 210
Answer:
x=266
Step-by-step explanation:
I'm sure if this is correct but this is how I did it seven times eight is 56 and you have to subtract that number by x so x would have to be bigger so it would be 56 minus 266
will give you 210
Answer:
x=-22
Step-by-step explanation:
7(8-x)=210
you would use the distributive property
56-7x=210
then subtract both sides by 56
-7x=154
then divide both sides by -7
x=-22

(-∞,-16)U(16/9,5)
Answer:
n = 3,4,5
Step-by-step explanation:
3n + 4 < 19
3n ≤ 15
n ≤ 5
10n/n+16 > 1
10n > n²+16
-n²+10n-16
(-n+2)(n-8)
n = 2 or n = 8
2 < n < 8
So 2<n≤5 = 3,4,5

The junior class sold 120 turkey dinner plates and 200 chicken dinner plates for a total of $2,150. The senior class sold 100 turkey plates and 300 chicken plates, raising $2,625. What was the cost of each turkey dinner plate? What is the cost of each chicken plate?
Answer:
Write the system of equations with 2 unknowns x and y denoting the prices of two types of chickens:
(1) 120x + 200y = 2150
(2) 100x + 300y = 2625
Solving the system of equations above we have 2 solutions:
x = 15/2 = $ 7.5 and y = 25/4 = $ 6.25

The measure of angle is
_________ degrees.
Answer:
65 degrees
Step-by-step explanation:
Triangle = 180 degrees
Straight line = 180 degrees
180 - 145 = 35
35 + 80 = 115
180 - 115 = 65 degrees
Find the angle of this sector.
6 cm
NEED ASAP
5 cm
Answer:
x ≈ 68.8°
Step-by-step explanation:
The length of the arc of a sector is calculated as
arc = circumference × fraction of circle , that is
6 = 2πr × [tex]\frac{x}{360}[/tex] = 2π × 5 × [tex]\frac{x}{360}[/tex] = 10π × [tex]\frac{x}{360}[/tex] ( multiply both sides by 360 )
2160 = 10πx ( divide both sides by 10π )
68.7549... = x , that is
x ≈ 68.8° ( to 1 dec. place )

The sketch of this crayon represents an irregular polygon. Find the area of the figure. 21.75 cm²
75 cm²
37.5 cm²
40.5 cm²
The total area of the sketch will be 40.5 cm².
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, The sketch of this crayon represents an irregular polygon.
Dimension of the polygon are given in the figure,
To calculate the area of the given figure first we need to break this into two parts:
The first one will be rectangular form with a length of 12.5 cm and a width of 3 cm
The second one will be in triangular form with a height of 2 cm and a base of 3 cm.
Area of rectangle = length * width
in our case,
Area of rectangle = 12.5*3
Area of rectangle = 37.5 square cm
Area of triangle = 1/2 base *height
In our case,
Area of triangle = 1/2* 3 * 2
Area of triangle = 3 square cm
So,
The total area of the sketch = area of rectangle +area of the triangle
The total area of the sketch = 37.5 + 3
The total area of the sketch = 40.5 Square cm
Therefore, the total area of the sketch will be 40.5 cm².

A(n+1)=A(n)+4 for n21 and A(1)=-6*
Helllllp
9514 1404 393
Answer:
74
Step-by-step explanation:
The recursive definition is for an arithmetic sequence with a first term of -6 and a common difference of 4.
The general term of such a sequence is ...
a(n) = a(1) +d(n -1)
This sequence is ...
a(n) = -6 +4(n -1) = 4n -10
Then for n = 21, the term is ...
a(21) = 4(21) -10 = 84 -10
a(21) = 74

Suppose a city with a population of 200,000 has been growing at a rate of 3% per year. If this rate continues, find the population of this city in 21 years. Round to the nearest whole number as needed (1 point)
Answer:
Growing at a rate of 3% per year : 200,000 x 3% = 6,000 population/ year
The population of this city in 21 years : 200,000 + ( 6,000 x 21 ) = 326,000 p
Step-by-step explanation:
The population of the city after 21 years is given by the exponential equation A = 372,059
What is exponential growth factor?The exponential growth rate is the value which increases exponentially over a period of time and
x ( t ) = x₀ ( 1 + r )ⁿ
x ( t ) is the growth at time t
x₀ is the initial value growth at time t = 0.
r is the growth rate expressed as percentage when r > 0
And , the decay rate when r < 0 , in percentage
t is the time in discrete intervals and selected time units
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Let the initial population of the city be x₀ = 200,000
Now , let the number of years be n = 21 years
Let the percentage of increase be r = 3 %
And , exponential growth formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( 21 ) = 200,000 ( 1 + 0.03 )²¹
On simplifying the equation , we get
x ( 21 ) = 200,00 ( 1.03 )²¹
x ( 21 ) = 200,000 ( 1.86029457 )
On further simplification , we get
x ( 21 ) = 3,72,058.914
On rounding the population , we get
x ( 21 ) = 372,059
Therefore , the value of A is 372,059
Hence , the exponential growth of the population after 21 years is 372,059
