Probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
Probability that Sara wins a raffle is given by the expression
P(win) = [tex]\frac{n}{n+3}[/tex]
Probability that Sara does not wins a raffle is given by
P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]
= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]
= [tex]\frac{n+3-n}{n+3}[/tex]
= [tex]\frac{3}{n+3}[/tex]
Thus, probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].

Answer:
sin(θ) = -√2/2
tan(θ) = -1
Step-by-step explanation:
The reference angle is arccos(√2/2) = 45°. The sine has the same magnitude, so the tangent (ratio of sine to cosine) has a magnitude of 1.
The angle is given as a 4th-quadrant angle. Both the sine and tangent are negative in the 4th quadrant.
sin(θ) = -√2/2
tan(θ) = -1
__
In the attachment, the angle of interest is 315° (7π/4). The given unit-circle coordinates are ...
(x, y) = (cos(θ), sin(θ))
tan(θ) = y/x
Answer:
sin(θ) = -√2/2
tan(θ) = -1

Answer:
The value of a = 5.
the value of b = 6.
Step-by-step explanation:
Given the points on the line
(6, 10)(a, 8)(4, b)(2, 2)Given that all of the points are on the same line and the line represents a linear function.
Thus, the slope between any two points must be the same.
First, determine the slope between (6, 10) and (2, 2)
(x₁, y₁) = (6, 10)
(x₂, y₂) = (2, 2)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 10] / [2 - 6]
= -8 / -4
= 2
Thus, the slope of the line = m = 2
Determine the value 'a'
(x₁, y₁) = (6, 10)
(x₂, y₂) = (a, 8)
Using the slope formula to determine the value of 'a'
Slope = [y₂ - y₁] / [x₂ - x₁]
As the slope between two points is 2.
now substitute slope = 2, (x₁, y₁) = (6, 10) and (x₂, y₂) = (a, 8) in the slope formula
Slope = [y₂ - y₁] / [x₂ - x₁]
2 = [8 - 10] / [a - 6]
2(a - 6) = 8 - 10
2a - 12 = -2
2a = -2 + 12
2a = 10
divide both sides by 2
a = 5
Therefore, the value of a = 5.
Determine the value 'b'
(x₁, y₁) = (2, 2)
(x₂, y₂) = (4, b)
Using the slope formula to determine the value of 'b'
Slope = [y₂ - y₁] / [x₂ - x₁]
As the slope between two points is 2.
now substitute slope = 2, (x₁, y₁) = (2, 2) and (x₂, y₂) = (4, b) in the slope formula
Slope = [y₂ - y₁] / [x₂ - x₁]
2 = [b - 2] / [4 - 2]
2(4 - 2) = b - 2
8 - 4 =b - 2
4 = b - 2
b = 6
Therefore, the value of b = 6

Answer:
Rhombus and angle 1 = 35
Step-by-step explanation:
The parallelogram has the same marking on each of its sides, indicating that all the sides are equal in length. It is, therefore, a rhombus.
It is given that one of the angles measures 110 degrees. The other angle is 70 degrees (because 180 - 110 = 70). Since it is bisected by a line, divide the angle by 2 (70/2). You get 35 degrees. Therefore, the measure of angle 1 is 35 degrees.
I hope this helps! :)

For each sequence, find the first 4 terms and the 10th term.
a) 3n + 4
b) 4n-5
Answer:
see explanation
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the formula, that is
(a)
a₁ = 3(1) + 4 = 3 + 4 = 7
a₂ = 3(2) + 4 = 6 + 4 = 10
a₃ = 3(3) + 4 = 9 + 4 = 13
a₄ = 3(4) + 4 = 12 + 4 = 16
Similarly substitute n = 10 for tenth term
a₁₀ = 3(10) + 4 = 30 + 4 = 34
(b)
a₁ = 4(1) - 5 = 4 - 5 = - 1
a₂ = 4(2) - 5 = 8 - 5 = 3
a₃ = 4(3) - 5 = 12 - 5 = 7
a₄ = 4(4) - 5 = 16 - 5 = 11, and
a₁₀ = 4(10) - 5 = 40 - 5 = 35
